Theoretical yield of water is 50.4g. Theoretical yield of a reaction is achievable if the limiting reactant has been identified.

In a chemical reaction, the limiting reactant, also known as the limiting reagent, controls how much product is produced. Calculating the theoretical yield of a reaction is achievable if the limiting reactant has been identified.

Because elements and compounds in an equilibrium chemical equation react in accordance with their mole ratios, there must be a limiting reactant.

2H[tex]_2[/tex] + O[tex]_2[/tex] [tex]\rightarrow[/tex] 2H[tex]_2[/tex]O

moles of H[tex]_2[/tex] = 11 gram/ 2=5.5moles

moles of O[tex]_2[/tex] = 45gram/32=1.40moles

O[tex]_2[/tex] is the limiting reagent

The saturation is 33%, the total unit weight is 107.5 lbs/ft^3, the void ratio is 0.43 and the porosity is 30%.

To calculate the saturation, we need to find the weight of water in the soil, which is 25% of the total weight of 215 lbs. So, the weight of water is 25/100 * 215 lbs = 53.75 lbs.

Next, we find the weight of solids in the soil, which is 215 lbs - 53.75 lbs = 161.25 lbs.

The saturation (S) is the ratio of the weight of water to the weight of solids in the soil and is calculated as follows:

S = 53.75 lbs / 161.25 lbs = 0.33 or 33%.

The total unit weight of the soil can be calculated using the following formula:

γ = (W_water + W_solids) / V

where W_water is the weight of water, W_solids is the weight of solids, and V is the volume of the soil.

Substituting the values, we get

γ = (53.75 lbs + 161.25 lbs) / (2 ft^3) =

= 215 lbs / (2 ft^3) = 107.5 lbs/ft^3

The void ratio (e) is the ratio of the volume of voids in the soil to the volume of solids in the soil, and can be calculated as follows:

e = V_voids / V_solids = (V - V_solids) / V_solids = (V - W_solids / γ_solids) / (W_solids / γ_solids)

Substituting the values, we get

e = (2 ft^3 - 161.25 lbs / 2.7) / (161.25 lbs / 2.7) = 0.43

Finally, the porosity (n) is the ratio of the volume of voids in the soil to the total volume of soil and is given by:

n = V_voids / V = e / (1 + e) = 0.43 / (1 + 0.43) = 0.43 / 1.43 = 0.30 or 30%.

The actual mass of sulfur yielded by this reaction is 23.4 g

The quantity of moles of a product created in relation to the amount of reactant consumed during a chemical reaction is measured in chemistry as yield, also known as reaction yield. The actual yield is calculated as the theoretical yield multiplied by 100 to get the percent yield.

To find the yield percent we use the equation: percent yield = actual yield/theoretical yield x 100

The theoretical yield for S is as follows:

71. g Cl2 x 1 mol Cl 2  x 1 mol x 32.1 g = 32.1 g S

                     71 g Cl     1           mol S

Lets start by calculating molar mass of AlCl₃

Molecular mass of Aluminium is 27 and that of Chlorine is 35.5

Al = 1 x 27 = 27

A triglyceride is a type of fat molecule made up of a glycerol molecule and three fatty acid molecules. Triglycerides are the most common type of fat found in food and are also stored in the body as a source of energy. When we eat foods high in fat, the body breaks down the triglycerides into their component fatty acids and glycerol and uses them as fuel. If we eat more fat than we can burn, the body stores the excess as body fat, which can contribute to obesity and other health problems if it accumulates in large amounts. Triglycerides play a role in the development of heart disease and other health problems, and their levels can be measured through a blood test.
