Answer:

Light is used by plants in a complex system that uses the light and several other resources to produce food. The more food= the more the plant grows, but too much food can be unhealthy for the plant. Some plants require more energy and others require less, this is because of the environment that they are in.

Explanation:

Plants' growth is significantly impacted by the quantity and quality of light they receive, a process called photomorphogenesis. Not all plants require identical light conditions, which is referred to as photoperiodism. Moreover, the ability of plants to use a variety of light wavelengths for photosynthesis allows them to adapt to different light conditions.

The amount of light can significantly impact the growth of plants. Different kinds of lights can foster varying developmental responses in the plants. This is known as Photomorphogenesis, growth and development of plants in response to light. Light influences many functions in a plant beyond photosynthesis, like the timing of flowering, the determination of whether the plant will produce fruit or seeds, and the plant's size.

Also, not all plants require the same amount of light for growth, nodding towards the concept of Photoperiodism. Some plants may flourish best under less-intensive light or might need different types of light to germinate or flower. For instance, fluorescent (cool white) light, high in blue wavelengths, encourages leafy growth. On the other hand, Incandescent lamps promote flowering in some plants due to high richness in red light.

Photosynthetic organisms, like plants, have a mixture of pigments that absorb energy from a wide range of wavelengths. This ability is especially useful for plants growing in competition for light, underwater, or on the rainforest floor because they have limited access to sunlight.

A covalent bond is formed by the attraction between the nuclei and the shared pairs of valence electrons between nonmetal atoms, and an atom's ability to form covalent bonds depends on the number of available valence electrons.

In a covalent bond, two atoms are held together by the attraction between the nuclei of a molecule's atoms and pairs of electrons between the atoms. The number of covalent bonds that an atom can form depends on the number of valence electrons in the atom.

Atoms typically form a characteristic number of covalent bonds in compounds. The shared electrons are attracted to the nuclei of both atoms, contributing to the formation of a molecule consisting of two or more atoms. Notably, covalent bonds form only between atoms of nonmetals.

The shared electrons come from the outermost shell of each atom, also known as the valence shell. When the valence electrons are shared, they create a mutual affinity that holds the atoms together, resulting in a covalent bond depicted as C:H or C-H in the simplest case.

Answer:

Explanation:

Parameter given:

Volume of gas in the container = 22.4L

Pressure on the gas = 1.0atm

Temperature of the gas = 0.0°C

Problem 1

Coverting 0.0°C to Kelvin:

In order to convert 0.0°C to Kelvin, we apply the formula:

              K = T(°C) + 273

Where T is the temperature in °C and K is the unknown temperature in Kelvin:

               K = 0.0 + 273 = 273K

Problem 2

The combined gas law is also known as the general gas law. It is expressed as:

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

The expression combines both Boyle's law and Charle's Law.

Problem 3

Parameters given:

Volume of gas in the container V₁ = 22.4L

Pressure on the gas P₁ = 1.0atm

Temperature = 273K

P₂ = 1.50atm

Unknown: The final volume, V₂ = ?

Solution

From the given problem, we know that the temperature is constant. We apply Boyle's law. Boyle's law states that "The volume of a fixed mass of gas varies inversely a the pressure changes if the temperature is constant".

It is expressed as P₁V₁ = P₂V₂

The unknown parameter is V₂, we make it the subject of the expression:

                    V₂ =[tex]\frac{P_{1}V_{1}  }{P_{2} }[/tex]

                     V₂ = [tex]\frac{1  x 22.4}{1.5}[/tex]

                     V₂ = 15L

Problem 4

The unknown here is the new volume V₂ at constant pressure.

Given parameters:

Volume of gas in the container V₁ = 22.4L

Pressure on the gas P is constant

Intial Temperature T₁ = 273K

Final Temperature T₂ = 100°C , converting to K gives, K = 100 + 273 = 373K

From the given parameters, the unknown and the conditions guiding the equation, we apply Charle's law. Charle's law states that "The volume of a fixed mass of gas is directly proportional to its absolute temperature provided pressure is constant".

                 it is expressed as: [tex]\frac{V_{1} }{T_{1} }  = \frac{V_{2} }{T_{2} }[/tex]

We then express the unknown V₂ as the subject of the formula:

                       V₂ = [tex]\frac{V_{1} T_{2} }{T_{1} }[/tex]

                       V₂ = [tex]\frac{22.4 x 373}{273}[/tex]

                        V₂ = 30.6L

Answer:

1.546 L.

Explanation:

where, P is the pressure of the gas in atm.

V is the volume of the gas in L.

n is the no. of moles of the gas in mol.

R is the general gas constant,

T is the temperature of the gas in K.

(P₁V₁T₂) = (P₂V₂T₁)

P₁ = 600.0 mmHg/760 = 0.789 atm, V₁ = 4.31 L, T₁ = 400 K.

P₂= 1.1 atm, V₂ = ??? L, T₂ = 200 K.

∴ V₂ =  (P₁V₁T₂)/(P₂T₁) = (0.789 atm)(4.31 L)(200 K)/(1.1 atm)(400 K) = 1.546 L.

Answer:

NaNO₃.

Explanation:

It is 90 g per 100 g water.

It is 110 g per 100 g water.

It is about 20 g per 100 g water.

It is about 40 g per 100 g water.

So, the most soluble salt at 50°C is NaNO₃.

The salt most soluble at 50°C is NaNO3 (sodium nitrate).

To determine the most soluble salt at 50°C, we need to consider the solubility data for each salt at this temperature. Generally, the solubility of salts increases with temperature, but the extent of this increase varies depending on the specific salt.

 The solubility of these salts at 50°C, in grams per 100 grams of water, is approximately as follows:

 - KNO3 (potassium nitrate): about 170 g/100 g H2O

- NaNO3 (sodium nitrate): about 220 g/100 g H2O

- KClO3 (potassium chlorate): about 24 g/100 g H2O

- NaCl (sodium chloride): about 360 g/100 g H2O

From these values, it is clear that NaNO3 has the highest solubility at 50°C, with a solubility of about 220 g/100 g H2O. This is higher than KNO3, KClO3, and even NaCl, which is known for its high solubility in water. Therefore, NaNO3 is the most soluble salt at 50°C among the options provided.

Answer:

504 J.

Explanation:

Q = m.c.ΔT,

where, Q is the amount of heat absorbed by ice (Q = ??? J).

m is the mass of the ice (m = 12.0 g).

c is the specific heat of the ice (c of steam = 2.1 J/g.°C).

ΔT is the difference between the initial and final temperature (ΔT = final T - initial T = 0.0°C - (-20.0°C) = 20.0°C).

∴ Q = m.c.ΔT = (12.0 g)(2.1 J/g.°C)(20.0°C) = 504 J.

Sorry if I'm wrong; please answer my last question I don't have much time; thank you

The statement is true. Stoichiometry is indeed the study of the quantitative relationship between the amounts of reactants used and products formed in a chemical reaction. It utilizes the coefficients from the balanced chemical equation to understand these relationships.

The statement is true. The study of the quantitative relationship between the amount of reactants used and the amounts of products formed by a chemical reaction is indeed called stoichiometry. This concept underlies the understanding of the classification of the reaction.

Chemical stoichiometry describes the quantitative relationships between reactants and products in chemical reactions. Coefficients from the balanced chemical equation provide the relative numbers of these chemical species, thus allowing a quantitative assessment of the relationships between the amounts of substances consumed and produced by the reaction.

For example, when calculating the amount of product generated from a given amount of reactant, any other reactants required are assumed to be available in stoichiometric amounts (or greater). These coefficients are used to derive stoichiometric factors that subsequently may be used for computations relating reactant and product masses, molar amounts, and other quantitative properties.

Answer:

1. [OH⁻] = 2.4 x 10⁻¹⁴ M.

2. [H₃O⁺] = 4.167 x 10⁻¹ M.

Explanation:

Firstly, we need to calculate the molarity of Mg(OH)₂:

M = (no. of moles of solute)/(V of the solution (L).

∴ M of MgCl₂ = (no. of moles of solute)/(V of the solution (L) = (1.2 x 10⁻¹⁴ mol)/(1.0 L) = 1.2 x 10⁻¹⁴ M.

1. [OH⁻]:

Mg(OH)₂ → Mg²⁺ + 2OH⁻.

∴ [OH⁻] = 2(1.2 x 10⁻¹⁴) = 2.4 x 10⁻¹⁴ M.

2. [H₃O⁺]:

∵ [H₃O⁺][OH⁻] = 10⁻¹⁴.

∴ [H₃O⁺] = 10⁻¹⁴/[OH⁻] = 10⁻¹⁴/(2.4 x 10⁻¹⁴ M) = 4.167 x 10⁻¹ M.

Solvent is the that part of solution which is present in large proportion and have ability to dissolve the solute.

Explanation:

Definition:

Solvent is the that part of solution which is present in large proportion and have ability to dissolve the solute. In simplest form it is something in which other substance get dissolve. The most widely used solvent is water, other examples are toluene, acetone, ethanol, chloroform etc.

Water is called universal solvent because of high polarity all polar substance are dissolve in it. Hydrogen is less electronegative while oxygen is more electronegative and because of difference in electronegativity hydrogen carry the partial positive charge while oxygen carry partial negative charge.

Water create electrostatic interaction with other polar molecules. The negative end of water attract the positive end of polar molecules and positive end of water attract negative end of polar substance and in this way polar substance get dissolve in it.

Example:

when we stir the sodium chloride into water the cation Na⁺ ions are surrounded by the negative end of water i.e oxygen and anion Cl⁻ is surrounded by the positive end of water i.e hydrogen and in this way all salt is get dissolved.
