Answer:
The PV of products will be constant.
Explanation:
Ideal gas equation- PV = nRT
where P is pressure of gas, V is volume of gas, n is number of moles of gas, R is gas constant and T is temperature (in Kelvin) of gas.
Now, number of moles of a gas remain constant with change in state variables.
So, if T is constant then the term "nRT" remins constant.
As PV is equal to nRT therefore PV will be constant if temperature is held constant.
In another way we can say if P is increased then V will decrease or vice versa.

Which of the following is most likely true about water in chemical systems?
A) Water dissolves nonpolar ionic compounds.
B) Water dissociates ionic compounds.
C) Water dissociates covalent molecules.
D) Water dissolves nonpolar covalent substances.
The water plays role in B) dissociation of ionic compounds.
Explanation:The presence of positively charged end and negatively charged end in the molecule is referred as polarity. Increasingly significant, the extremity of water is in charge of successfully dissolving other polar particles, for example, sugars and ionic mixes, for example, salt. Ionic mixes break down in water to shape particles. This is critical to recall in light of the fact that for most natural responses to happen, the reactants must be disintegrated in water.
Since water can break down such huge numbers of basic substances, it is known as the all-inclusive dissolvable. Substances that can't be broken down by water, (for example, oils) are called fat dissolvable and are nonpolar, non-ionic exacerbates that are firmly covalently reinforced.
D) Water dissolves nonpolar covalent substances. Due to its curved form and an uneven distribution of oxygen and hydrogen atoms' electrons, water is a polar molecule. Because of this, it makes a great solvent for polar and ionic chemicals. Water is not a good solvent for nonpolar covalent compounds, though.
Because they lack stable electric dipoles, nonpolar covalent compounds like hydrocarbons (such as oil, gasoline) and certain gases (such as methane, oxygen) do not interact with water strongly. They do not dissolve well in water because they have a tendency to resist water molecules. Because oil is nonpolar and does not dissolve in the polar water, oil and water do not combine.
Therefore, the notion that water dissolves polar and ionic molecules but ineffectively dissolves nonpolar covalent chemicals is most likely accurate. The right response is D.

Answer:
The average atomic mass is 24.30 amu.
Explanation:
When there are at least 2 isotopes for an atom, each with its own atomic mass, we can calculate an average atomic mass (AAM), which considers the mass of each isotope and its relative abundance. The mathematical expression is:
[tex]AAM=\frac{\Sigma m_{i} \times ab_{i} }{\%100}[/tex]

c) 1/1840 the mass of a C-12 atom
d) 1/1840 the mass of a hydrogen atom
Answer:
1/1840 the mass of a C-12 atom
Choice C is correct
Explanation:
The relative mass of an electron is 1/1840 the mass of a C-12 atom . Atomic mass units are expressed relatively to the atomic mass unit of an unbound neutral carbon-12 atom.
d) 1/1840 of hydrogen atom mass is the relative electron mass.
Explanation:The hydrogen gas is the lightest element and its atomic mass is [tex]\bold{1.67 \times 10^{-27} \ kg}[/tex], same as the mass of proton because it has no neutron and contains one proton and one electron in its atom. But it loses an electron to gain stable electronic configuration leaving only a proton in its atomic structure.
We know, Mass of an electron = [tex]9.11 \times 10^{-31} \ kg[/tex]
[tex]\text{Relative mass of electron} = \frac{\text{Mass of proton}}{\text{Mass of electron}}[/tex]
Relative mass of electron = [tex]\frac{1}{1840}[/tex] the mass of proton
Relative mass of electron = [tex]\frac{1}{1840}[/tex] the mass of hydrogen atom.
In your own words, write a paragraph to compare and contrast endothermic and exothermique reactions. Give at least one example of each
Please answer ASAP!! Don’t google it
Explanation:
Endothermic vs. Exothermic Reactions. An endothermic reaction occurs when energy is absorbed from the surroundings in the form of heat. Conversely, an exothermic reaction is one in which energy is released from the system into the surroundings. The terms are commonly used in the physical sciences and chemistry.
Final answer:
Endothermic reactions absorb energy, causing environmental temperature to decrease, like in photosynthesis, while exothermic reactions release energy, increasing environmental temperature, as seen in the combustion of substances like paper. Energy changes in these reactions are due to bond forming and breaking, with endothermic reactions needing energy input and exothermic reactions releasing energy.
Explanation:
Chemical reactions can broadly be classified into two types: endothermic and exothermic reactions. Endothermic reactions absorb energy from the surroundings, often in the form of heat, leading to a temperature decrease in the environment. A classic example of an endothermic reaction is photosynthesis in plants, where solar energy is absorbed to convert carbon dioxide and water into glucose and oxygen. On the other hand, exothermic reactions release energy, usually causing a temperature increase.
Combustion of substances, such as burning paper, is an exothermic reaction because it releases heat into the surroundings. The energy difference between the reactants and products is what drives these endothermic and exothermic processes, with the former having higher potential energy in the products and the latter having higher potential energy in the reactants.
When considering the energy change during a chemical reaction, it's the formation and breaking of chemical bonds that result in energy being absorbed or released. Endothermic reactions require energy to break bonds within the reactants, leading to a higher potential energy in the products compared to the reactants.
Conversely, exothermic reactions release energy when new bonds are formed in the product molecules, which possess less energy than the reactants. If we were to draw energy graphs for these reactions, an endothermic reaction graph would depict an upward curve from reactants to products, reflecting an input of energy, whereas an exothermic reaction graph would show a downward curve, indicating that energy is released.

(Choice D)
D
There is more space between individual atoms at lower temperatures, which means colder water has a lower density.
Ice has a lower density than liquid water because hydrogen bonding causes water to crystallize with more empty space between molecules than in the liquid state.
Explanation:Hydrogen bonding is a strong intermolecular force that occurs when hydrogen atoms are covalently bonded to highly electronegative atoms (e.g., nitrogen, oxygen, or fluorine). These hydrogen bonds result in attractive forces between neighboring molecules, contributing to unique properties like high boiling points in substances such as water and the stability of biomolecules like DNA and proteins.
Hydrogen bonding causes water to crystallize with more empty space between molecules than in the liquid state. This is because ice has a unique crystal structure known as a hexagonal lattice, in which water molecules form open spaces or voids between them. The hydrogen bonds in ice are more stable and rigid, allowing the water molecules to arrange themselves in a way that maximizes the empty space between them.

an alloy contains 66 g of pure zinc. what is the percentage of zinc in the alloy? express your answer to two significant figures and include the appropriate units.
Due to lack of total mass information of the alloy, we cannot calculate the percentage of zinc directly. Instead, for a zinc-and-oxygen compound with a known mass, the percentage of zinc can be found by dividing the mass of zinc by the total mass of the compound and multiplying by 100, which in a given example, results in approximately 80.35% zinc by mass.
To calculate the percentage of zinc in the alloy, we need to know the total mass of the alloy. Since only the mass of pure zinc (66 g) is given and not the total mass of the alloy, we can't calculate the percentage directly. However, we can calculate the percentage composition of zinc in a compound using its mass before and after decomposition. In the given reference, a 20.00 g sample of a zinc-and-oxygen compound is decomposed and 16.07 g of zinc remains, which is used to determine the percent composition.
To calculate the percentage of zinc in the compound:
Divide the mass of zinc (16.07 g) by the total mass of the compound (20.00 g).
Multiply the result by 100 to get the percentage.
So the calculation will be (16.07 g \/ 20.00 g) \\times 100%, which gives about 80.35%. This means that by mass, the compound is mostly zinc.

Explanation:
Do Remember there are two states for an Electron Configuration.
Excited and Ground
For brevity
Ground State Electron Configuration:
Naturally, atoms use the lowest energy possible, and this state in which an atom is at the lowest energy level possible is the Ground State.
Final answer:
The ground state electron configuration for vanadium (V) is [Ar] 4s² 3d³, as V follows the 3d orbital filling sequence after Ca and before Cr with its half-filled 3d5-shell.
Explanation:
The ground state electron configuration for the element vanadium (V), which has the atomic number 23, is a topic related to the transition elements in chemistry. The electronic configuration for vanadium can be tricky due to the closeness in energy levels of the 4s and 3d orbitals. However, from the given reference information and understanding the sequence of orbital filling for transition elements, we can deduce that after potassium (K) and calcium (Ca), where the 4s orbital is filled, the 3d electrons begin to be filled for scandium (Sc), titanium (Ti), and then vanadium (V). Keeping in mind the discontinuity that occurs at chromium (Cr), vanadium's ground state configuration can be written using the knowledge that V comes just before Cr. Therefore, vanadium’s electron configuration is [Ar] 4s² 3d³, following the 3d orbital filling after Ca and before the half-filled 3d5-shell configuration of Cr.

David has two containers of two different gases at the same temperature and pressure. David could assume all of following EXCEPT _________.
A. when the temperature is increased, the volume of both containers will increase
B. when the pressure is increased, the volume of both containers will decrease
C. both containers contain the same number of gas particles
D. when the pressure is decreased, the temperature of both containers will increase
Answer:
David could not assume that:when the pressure is decreased, the temperature of both containers will increase (option D).
Explanation:
Since this question has only one answer, you must assume that both containers are identical, i.e. have the same volume.
Using the ideal gas equation pV = nRT you can conclude that pressure and temperature are directly related, i.e. if the pressure is decreased, the temperature will decrease proportionally, which is opposite to the assumption that when the pressure is decreased, the temperature of both containers will increase.
On the other hand, from the same equation, you can tell the relationship between the other variables and conclude that the other choices are valid assumptions:
A. when the temperature is increased, the volume of both containers will increase:
Correct: pV = nRT shows that volume and temperature are directly related: when T increase, V increase)
B. when the pressure is increased, the volume of both containers will decrease
Correct: pV = nRT shows that p and V and inversely related, so when p is incrased, V will decrease.
C. both containers contain the same number of gas particles
Correct, only if the two containers are identical: since the two containers of the two different gases are at the same temperature and pressure, the equation pV = nRT, shows that if the volumes are equal the number of particles are the same.
David cannot assume option C, which states both containers contain the same number of gas particles since he only knows the temperature and pressure of both gases. Without knowledge of the volume, he cannot determine the number of particles via the Ideal Gas Law.
Explanation:In this question, David does not have enough information to assume that C. both containers contain the same number of gas particles. This is because simply having the same temperature and pressure for two different gases does not confirm they have the same number of particles.
In the units of Ideal Gas Law, which states PV = nRT, 'P' stands for pressure, 'V' is volume, 'n' indicates number of moles i.e., the number of particles, 'R' is the universal gas constant, and 'T' is Temperature.
From this, we can see that the number of gas particles is proportional to the pressure and volume, and inversely proportional to the temperature. Therefore, without information about volume, we can not determine if both containers have the same number of particles.
The other possibilities regarding pressure, temperature, and volume changes are governed by the principles of gas laws, such as Boyle's, Charles', and Gay-Lussac's laws.

Answer:
D. Freezing
Explanation:
Please mark brainliest and have a great day!
Answer:
A. Melting
Explanation:
In the above question we noticed that there is a passage from a regular and well compacted carbon dioxide molecules to molecules in a less compact and lower density pattern after a period of heating. According to this description we can conclude that a physical process called "Melting" occurred, which is the process, where a solid substance (which has very compacted molecules) when heated becomes a liquid substance, with less compacted molecules and lower density.
Melting explains the changeover from heating to solid state to liquid state. Heating causes the temperature of the substance to rise to its melting point. The temperature does not rise while fusion is taking place, that is, only after all the substance has gone into liquid state does the temperature rise again.
The melting point of a substance is the temperature at which that substance changes from solid to liquid state.

3*10^8 m/s * 10^9 nm/m / 7.26*10^14 s^-1= λ
=413.22 nm
λ=413 nm
Answer : The wavelength of violet light is, 413 nm
Explanation :
Formula used :
[tex]\nu=\frac{c}{\lambda}[/tex]
where,
[tex]\nu[/tex] = frequency of violet light = [tex]7.26\times 10^{14}Hz=7.26\times 10^{14}s^{-1}[/tex]
As we know that, [tex]Hz=s^{-1}[/tex]
[tex]\lambda[/tex] = wavelength of violet light
c = speed of light = [tex]3.00\times 10^8m/s[/tex]
Now put all the given values in the above formula, we get:
[tex]7.26\times 10^{14}s^{-1}=\frac{3.00\times 10^8m/s}{\lambda}[/tex]
[tex]\lambda=\frac{3.00\times 10^8m/s}{7.26\times 10^{14}s^{-1}}[/tex]
[tex]\lambda=4.13\times 10^{-7}m=4.13\times 10^{-7}\times 10^9nm=413nm[/tex]
