A
Increase the temperature to 70∘^{\circ}
B
Increase the pH with the addition of a base
C
Decrease the temperature to 40∘C
D

The factor that will increase the rate of the function of the enzyme A is increasing the temperature to 70°C (option A).
What is an enzyme?Enzymes are biological catalysts meaning that they regulate the rate of biochemical reactions in living cells.
Enzymes lower the activation energy of a reaction, which is the required amount of energy needed for a reaction to occur. Enzymes do this by binding to a substrate and holding it in a way that allows the reaction to happen more efficiently.
The factors that affect the rate of function of na enzyme are as follows:

Calculate the mass of water of hydration lost and the mass of dehydrated salt remaining (CuSO4(s)).
According to the concept of molar mass, mass of water of hydration lost is 90 g/mole and mass of dehydrated salt is 159.68 g/mole as the mass of copper sulfate pentahydrate is 249.68 g/mole.
What is molar mass?Molar mass of a compound or a molecule is defined as the mass of the elements which are present in it.The molar mass is considered to be a bulk quantity not a molecular quantity. It is often an average of the of the masses at many instances.
The molecular mass and formula mass are used as synonym for the molar mass.It does not depend on the amount of substance which is present in the sample.It has units of gram/mole.
Molar masses of an element are given as relative atomic masses while that of compounds is the sum of relative atomic masses which are present in the compound.
Copper sulfate along with water of hydration has mass of 249.68 g/mole.On heating , the mass of water of hydration lost =90 g/mole

A sample consists of ethanol and water.
Ethanol has a density of 0.79 g/mL.
Which liquid will float on top of the sample
- the ethanol or the water?
Density of water is 1g/cc whereas ethanol is 0.79g/cc
So density of ethanol is less than water hence ethanol will float on water
What is density ?
density is the mass of a material substance per unit volume. d = M/V, where d is density, M is mass, and V is volume, is the formula for density. Grams per cubic centimeter are a typical unit of measurement for density. For instance, while Earth has a density of 5.51 grammes per cubic centimeter, water has a density of 1 grammes per cubic centimeter. Another way to state density is in kilograms per cubic meter (in meter-kilogram-second or SI units)

a sample of br2(g) takes 46.0 min to effuse through a membrane. how long would it take the same number of moles of ar(g) to effuse through the same membrane?
From the equation of Graham's law of diffusion of gases, it would take the same number of moles of Ar(g) 23 minutes to effuse through the same membrane.
What factors affect the rate of diffusion of gases?The rate of diffusion or effusion of gases is affected by temperature, concentration, pressure, and the molecular weight of the gas.
The gas law that describes how the molecular weight or vapor density of a gas affects the rate of diffusion is Graham's law of diffusion of gases.
Mathematically, Graha's law of diffusion of gases is given below as follows:
R₁ / R₂ = √(M₂ / M₁) or T₁ / T₂ = √(M₁ / M₂)
where;
R₁ is the rate of diffusion of gas 1
T₁ is the time of diffusion of gas 1
M₁ is the molecular weight of gas 1
R₂ is the rate of diffusion of gas 2
T₂ is the time of diffusion of gas 2
M₂ is the molecular weight of gas 2
Substituting the values in the second equation:
The molecular weight of Br₂ = 160 g/mol
The molecular weight of Ar = 40 g/mol
46 / T₂ = √(160 / 40)
T₂= 46 / 2

The four main components of a modern detergent are builders (50% by weight), surfactants (15%), bleach (7%), and enzymes (2%).
What is the use of the components in the detergent?A detergent can be described as a surfactant or a mixture of surfactants with cleansing properties in dilute solutions. These substances are similar to soap but are more soluble in hard water due to the polar sulfonate is less likely than the polar carboxylate of soap to bind ions in hard water.
Builders are water softeners and their anions react with cations to form insoluble compounds which precipitate onto fabrics and washing machines and which are hard to remove.
Surfactants provide absorption and emulsification of soil into the water and also by reducing the surface tension of water to improve wetting. The main function of bleaches is oxidizable organic stains, which are usually of vegetable origin.

Each magnesium chloride (MgCl₂) molecule dissociates into 3 ions in total.
Magnesium chloride (MgCl₂) is a salt which means that, upon dissolving in water, it will dissociate, giving positively charged metal cations (here, magnesium ions) and negatively charged anions formed from nonmetals (here, chloride ions). The balanced reaction equation for magnesium chloride (MgCl₂) dissociation looks like this:
MgCl₂(aq) → Mg²⁺(aq) + 2Cl⁻(aq)
We can see that, upon dissociation, each molecule of magnesium chloride forms a single magnesium ion (Mg²⁺) and two chloride ions (Cl⁻). So, in total, 1 + 2 = 3 ions are formed from each unit of magnesium chloride.

When a chemical reaction happens, the atoms in the reactants are rearranged to create compounds with various chemical characteristics. Although identical atoms are present in both the reactants and the products, sodium chloride was produced by rearranging the atoms in the reactants. The reactants lacked sodium chloride.
Sodium is a soft, silver-colored metal that may be sliced with a knife. With water, pure sodium metal reacts violently (and even explosively), creating sodium hydroxide, hydrogen gas, and heat.
2Na(s) + 2H₂O(l) ⟶ 2NaOH(aq) + H₂(g)
Chlorine is a poisonous yellow-green gas with a pungent smell.

how does hydrogenation affect unsaturated fats? a. it changes them so they are more water-soluble. b. it changes solid fats to trans fatty acids. c. it changes them to polyunsaturated fats as it removes hydrogen atoms. d. it adds antioxidants to them, creating a better-preserved product. e. it adds hydrogen atoms to their chains, making them more saturated.
Hydrogenation affects unsaturated fats by adding hydrogen atoms to their unsaturated chains and making them be more saturated.
What is unsaturation?Unsaturation in organic compounds is an indication of the presence of double or triple bonds in one or more C-C bonds in the structure of the compounds.
Saturated organic compounds do not have double or triple C-C bonds in them.
Unsaturated compounds, therefore, have the tendency to undergo addition reactions due to the presence of the double/triple bond.
Hydrogenation of unsaturated fats is an additional reaction. The hydrogen atoms attach themselves by pairing with the lone electron pairs in the double or triple bonds.
Thus, the addition of hydrogen makes unsaturated compounds to be more saturated.
Saturated compounds, on the other hand, can only undergo substitution reactions instead of addition reactions.
