What does it take to ne classified as a "rogue wave".

Answer:

Position D

Explanation:

One fourth of the Moon will be visible from Earth when the Moon is in position D. The reason why this is the right position is that the Moon will be in a position where the majority of its surface that is lighted by the Sun is facing the Sun. On the other hand, the angle is just right that about one quarter of the lighted part of the Moon is also facing the Earth. This will result in a perception from the Earth's view point that the Moon is lighted at one quarter of its surface.

rows organize the number of orbitals in an atom

Answer: The correct answer is Option d.

Explanation:

Elements in a periodic table are distributed in 7 Periods and 18 Groups. The elements are distributed on the basis of increasing atomic numbers.

Periods are known as horizontal rows and groups are known as vertical columns.

In a period, the number of shells around the nucleus remains the same but the valence electrons keep on increasing as we move from left to right.

For Example: In Period 2, the number of valence shells increases from 1 (for lithium) to 8 (for neon)

In a group, the number of shells around the nucleus keeps on increasing but the valence electrons remains the same as we move from top to bottom.

For Example: For Group 1, the number of valence electrons are 1

Hence, the correct answer is Option d.

Answer:

up quark

Explanation:

Answer:

up quark

Explanation:

Carbon–oxygen bond. A carbon–oxygen bond is a polar covalent bond between carbon and oxygen. Oxygen has 6 valence electrons and prefers to either share two electrons in bonding with carbon, leaving the 4 nonbonding electrons in 2 lone pairs :O: or to share two pairs of electrons to form the carbonyl functional group.

The type of bond that forms between carbon and oxygen is a covalent bond.

Covalent bonding involves the sharing of electrons between atoms. In the case of carbon and oxygen, both atoms can achieve a more stable electron configuration by sharing electrons.

Carbon has four valence electrons, and oxygen has six valence electrons. When carbon and oxygen atoms come together, they can share two electrons to form a double bond.

In this arrangement, carbon shares two electrons with oxygen, and oxygen shares two electrons with carbon. This sharing of electrons allows both atoms to achieve a full outer electron shell, satisfying the octet rule.

The rate of a chemical reaction refers to how fast the reaction proceeds. It can be expressed as the change in concentration of a reactant or product with time. For example, if a 1.00 M aqueous solution of substance A is converted to substance B, the reaction rate can be measured by tracking the decrease in the concentration of A or the increase in the concentration of B over a specific time interval.

Answer:

Glucose

Explanation:

There are two types of respiration:

1. Aerobic respiration  

2. Anaerobic respiration

Aerobic respiration

It is the breakdown of glucose molecule in the presence of oxygen to yield large amount of energy. Water and carbon dioxide are also produced as a byproduct.

Glucose + oxygen → carbon dioxide + water + 38ATP

Anaerobic Respiration

It is the breakdown of glucose molecule in the absence of oxygen and produce small amount of energy. Alcohol or lactic acid and carbon dioxide are also produced as byproducts.  

Glucose→ lactic acid/alcohol + 2ATP + carbon dioxide

This process use respiratory electron transport chain as electron acceptor instead of oxygen. It is mostly occur in prokaryotes. Its main advantage is that it produce energy (ATP) very quickly as compared to aerobic respiration.  

Steps involve in anaerobic respiration are:

Glycolysis

Glycolysis is the first step of both aerobic and anaerobic respiration. It involve the breakdown of one glucose molecule into pyruvate and 2ATP.

Fermentation

The second step of anaerobic respiration is fermentation. It involve the fermentation of pyruvate into lactic acid or alcohol depending upon the organism in which it is taking place. There is no ATP produced in this step, however carbon dioxide is released.

The orbital 1s is filled with two electrons and their spinning direction is opposite and also electrons of 2s.

3p contains (3 electrons) should fill the 3 orbitals firstly. Every orbital contains 1 electron and be in the same spin direction.

So, the right choice is c.

A is wrong because 2 electrons of 3p are paired in the first orbital before filling every orbital.

B is wrong because the 2 electrons of 1s and 2s are in the same direction and also 2 electrons of 3p are paired in the first orbital before filling every orbital.

D is also wrong the 2 electrons of 1s and 2s are in the same direction and the electron in the second orbital of 3p are in opposite direction of the other 2 electrons.

23.0g of Zn is equivalent to 0.35 moles. Given that CuCl2 is in excess, the reaction will result in an equal number of moles of ZnCl2, i.e., 0.35 moles.

This is a question about the stoichiometry of the reaction between zinc (Zn) and copper chloride (CuCl2). We are given 23.0g of Zn and asked how many moles of zinc chloride (ZnCl2) will be produced, assuming that copper chloride is present in excess.

The relevant reaction from the examples given is:
Zn(s) + 2HCl(aq) → ZnCl2(aq) + H2(g)

First, we need to calculate the moles of Zn. We do this using the molar mass of Zn, which is approximately 65.38 g/mol.

moles of Zn = 23.0 g / 65.38 g/mol = 0.35 mol

Because CuCl2 is in excess and the reaction stoichiometry is 1:1, we can assume all the zinc will react to form ZnCl2. Therefore, 0.35 moles of Zn will produce 0.35 moles of ZnCl2.

https://brainly.com/question/30218216

#SPJ12

0.351 moles of ZnCl2 will be produced from 23.0g of Zn with CuCl2 available in excess.

In order to determine the number of moles of ZnCl2 produced, we need to use the stoichiometry of the reaction. Based on the balanced equation: CuCl2 (aq) + Zn (s) → ZnCl2 (aq) + Cu (s)

We can see that the mole ratio between ZnCl2 and Zn is 1:1. Therefore, the number of moles of ZnCl2 produced will be the same as the number of moles of Zn used.

Since we have 23.0g of Zn, we can convert this mass into moles using the molar mass of Zn:

23.0g Zn x (1 mol Zn / 65.38g Zn) = 0.351 mol Zn

Therefore, 0.351 moles of ZnCl2 will be produced from 23.0g of Zn with CuCl2 available in excess.

Answer:

0.98 g of H₂

Explanation:

the balanced equation for the reaction is

Mg + 2HCl ---> MgCl₂ + H₂

molar ratio of Mg to H₂ is 1:1

number of Mg moles reacted = 12 g/ 24.3 g/mol = 0.49 mol

according to molar ratio

when 1 mol of Mg reacts 1 mol of H₂ is formed

therefore when 0.49 mol of Mg reacts - 0.49 mol of H₂ forms

therefore mass of H₂ formed = 0.49 mol x 2 g/mol = 0.98 g

mass of H₂ formed is 0.98 g

Approximately 0.988 grams of H2 will be produced from 12 grams of Mg according to the equation provided. This is calculated by first converting the mass of Mg to moles, then using the stoichiometric relationship to find the moles of H2, and finally converting moles of H2 back to grams.

To solve this problem, you need to know that in the balanced chemical equation, the coefficients of the reactants and the products represent the mole ratios in which they react and form. In the provided equation, 'Mg + 2HCl → MgCl2 + H2', there is a 1:1 ratio between Mg and H2. So, we first convert grams of Mg into moles using its molar mass. The molar mass of Mg is approximately 24.305 grams per mole. Therefore, the amount of moles of Mg we have is 12g (amount given) divided by 24.305g/mol (molar mass of Mg) which is approximately 0.494 moles of Mg.

Since Mg and H2 are in a 1:1 ratio, we also have approximately 0.494 moles of H2. To convert the moles of H2 to grams, we multiply by its molar mass (about 2 grams per mole). So, the mass of H2 produced is 0.494 moles times 2g/mol which equals approximately 0.988 grams of H2.

The reaction favor product formation

Explanation:

Equilibrium constant of a chemical reaction is the value of its reaction quotient at chemical equilibrium. Also it is defined as the ratio of the product of concentration of products to the product of concentration of reactants each term raised to power equal their stochiometric coefficients.  

so, for the reaction,

The equilibrium constant can be expressed as following:

[tex]K_{eq}=\frac{[H_2S]^2}{H_2]^2\times [S_2]}[/tex]

where  concentration of reactants and products is expressed in molarity Molarity=(no of moles/ Volume L)

So,

[H₂] = (0.50 mol / 1 L) = 0.50 M

[S₂] = (0.02 mol / 1 L) = 0.020 M

[H₂S] = (68.5 mol / 1 L) = 68.5 M

∴ K_{eq}=\frac{[68.5]^2}{0.50]^2\times [0.020]}=9.4*10^5

As the value of K is greater than 1, the reaction favor product formation.

Answer:continental drift

Explanation:

Answer:

Option (B)

Explanation:

The continental drift is defined as the shifting of the continents over the large water body with respect to the poles. These continents moved from one place to another across the line of different latitudes and longitudes, experiencing various types of climatic conditions, due to which the ocean water currents has been significantly affected. This presence and continuous motion of continents affects the direction of the ocean currents that moves from the equatorial to the polar region.

Thus, over the earth's geological history, the ocean currents are undergoing changes due to the continental drifting.

Hence, the correct answer is option (B).

Answer:

No, only the wiehgt, because the gravitational pull on the two, are diffrent. 3kg on the moon may be 6kg here on earth. but in the end, the rock still holds however much rock it held in the begining.

Explanation:

Final answer:

The mass of a moon rock remains unchanged when moved from the moon to Earth. However, its weight would increase due to the stronger gravitational pull of the Earth.

Explanation:

When a 3 kg moon rock is moved from the moon to the earth, the mass of the rock does not change. Mass is a measure of the amount of matter in an object and is constant regardless of location. However, the weight of the rock, which depends on the gravitational pull it experiences, will change. On the Moon, where the acceleration due to gravity is only 1.67 m/s², the rock would weigh less than it does on Earth, where the acceleration due to gravity is 9.80 m/s². Thus, while the mass remains unchanged, the weight of the moon rock increases when it is moved to Earth because it is in a region with stronger gravity.

The answer is:

The new volume will be 1 L.

[tex]V_{2}=1L[/tex]

To solve the problem, since we are given the volume and the first and the second pressure, to calculate the new volume, we need to assume that the temperature is constant.

To solve this problem, we need to use Boyle's Law. Boyle's Law establishes when the temperature is kept constant, the pressure and the volume will be proportional.

Boyle's Law equation is:

[tex]P_{1}V_{1}=P_{2}V_{2}[/tex]

So, we are given the information:

[tex]V_{1}=2L\\P_{1}=50kPa\\P_{2}=100kPa[/tex]

Then, isolating the new volume and substituting into the equation, we have:

[tex]P_{1}V_{1}=P_{2}V_{2}[/tex]

[tex]V_{2}=\frac{P_{1}V_{1}}{P_{2}}[/tex]

[tex]V_{2}=\frac{50kPa*2L}{100kPa}=1L[/tex]

Hence, the new volume will be 1 L.

Answer:

1. Evaporation

2. Condensation

3. Precipitation

4. Runoff

Explanation:

The water cycle shows how water moves on the earth as it passes through different phases.

Water on land is stored in oceans, rivers and other water bodies. This water coupled with those in plants and animals are turned into vapor through EVAPORATION. Evaporation facilitates the movement of water on the surface into the atmosphere.

In the atmosphere, the vapor condenses on dust particles found up there. The vapors forms a nuclei around the dust particles and water condenses at the saturated vapor pressure. This forms cloud.

As the water collects more and more, gravity forces the water to fall in form of PRECIPITATION. The precipitation can be in form of snow or rainfall.

When precipitation occurs, they move on the surface as SURFACE RUNOFFS. Some of the runoff goes back into oceans and rivers. Others infiltrates into the ground and collects in the ground water pool under the subsurface. Subsurface water can also get into into other water bodies when the water table coincides with the steam level.

The water in these bodies can then go into the cycle again. The sun is the source of energy for this process.

The water cycle consists of four main steps including evaporation/sublimation, condensation/precipitation, subsurface water flow, and surface runoff/snowmelt, representing a continuous movement of water on, above, and below the surface of the Earth.

According to the water cycle diagram: 1 corresponds to evaporation/sublimation, where water from the oceans turns into water vapor, due to the sun's energy. 2 represents condensation or precipitation, which takes place when the water vapor cools down and forms clouds, eventually falling as rain or snow. 3 stands for subsurface water flow - the movement of water underground, within the soil, which occurs after the water infiltrates the soil. Lastly, 4 is related to surface runoff/snowmelt - when excess water from rain, meltwater, or other sources flows on the Earth's surface and returns to the oceans completing the cycle.

Explanation:

An aerosol is a suspension of fine solid particles or liquid droplets, in air or another gas.[1] Aerosols can be natural or anthropogenic. Examples of natural aerosols are fog, dust, forest exudates and geyser steam. Examples of anthropogenic aerosols are haze, particulate air pollutants and smoke.[dubious – discuss][1] The liquid or solid particles have diameters typically <1 μm; larger particles with a significant settling speed make the mixture a suspension, but the distinction is not clear-cut. In general conversation, aerosol usually refers to an aerosol spray that delivers a consumer product from a can or similar container. Other technological applications of aerosols include dispersal of pesticides, medical treatment of respiratory illnesses, and convincing technology.[2] Diseases can also spread by means of small droplets in the breath, also called aerosols (or sometimes bioaerosols).[3]

Aerosol science covers generation and removal of aerosols, technological application of aerosols, effects of aerosols on the environment and people, and other topics.

Aerosols, the atmospheric particles, consist of: D. Solid and liquid

Suspension is a heterogeneous mixture where the solute particles get suspended throughout the bulk of the solvent, then left floating around freely in the medium.

Aerosols are come from volcanoes, dust storms, fires, vegetation, sea spray, burning of fossil fuels and land use. Primary aerosols are those particles emitted directly into the atmosphere. It is because the different sources of aerosols mix on the earth's surface. Warming aerosols are include black carbon and dark soot. Cooling aerosols include dust, sulfate particles and sea spray.

Aerosols can influence the Earth's climate in two ways. When the sky is clear (devoid of clouds), aerosols can reflect incoming sunlight back to outer space
