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.

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)

The factor that will increase the rate of the function of the enzyme A is increasing the temperature to 70°C (option A).

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:

Each enzyme has an optimum pH range. This means that changing the pH outside of this range will slow enzyme activity, however, raising temperature generally speeds up a reaction, and lowering temperature slows down a reaction.

Hydrogenation affects unsaturated fats by adding hydrogen atoms to their unsaturated chains and making them be more saturated.

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.

The force required to move the body with the mass of 5 kg with acceleration of 10 m/s² is 50 Newtons.

Force is defined as a push or pull exerted on an object as a result of the interaction of the object with another object.

It can also be defined as an external factor that, when used, alters or has the potential to alter the state of the body.

Force can be expressed as

Force = mass x acceleration

Given, Mass = 5 kg

Acceleration = 10 m/s²

So, F = m x a

F = 5 kg x 10 m/s²

F = 50 kgm/s²

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.

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%).

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.

Taking into account the reaction stoichiometry, a mass of 7.57 grams of MgBr₂ is formed when one grams of magnesium reacts with 5 g of bromine.

In first place, the balanced reaction is:

Mg  + Br₂ → MgBr₂

By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:

The molar mass of the compounds is:

Then, by reaction stoichiometry, the following mass quantities of each compound participate in the reaction:

The limiting reagent is one that is consumed first in its entirety, determining the amount of product in the reaction. When the limiting reagent is finished, the chemical reaction will stop.

To determine the limiting reagent, it is possible to use a simple rule of three as follows: if by stoichiometry 24.31 grams of Mg reacts with 159.8 grams of Br₂, 1 grams of Mg reacts with how much mass of Br₂?

mass of Br₂= (1 grams of Mg× 159.8 grams of Br₂) ÷24.31 grams of Mg

mass of Br₂= 6.57 grams

But 6.57 grams of Br₂ are not available, 5 grams are available. Since you have less mass than you need to react with 1 grams of Mg, Br₂ will be the limiting reagent.

Considering the limiting reagent, the following rule of three can be applied: if by reaction stoichiometry 24.31 grams of Mg form 184.11 grams of MgBr₂, 1 grams of Mg form how much mass of MgBr₂?

mass of MgBr₂= (1 grams of Mg× 184.11 grams of MgBr₂)÷ 24.31 grams of Mg

mass of MgBr₂= 7.57 grams

Then, a mass of 7.57 grams of MgBr₂ can be produced.
