Answer 2

Calculating the Amount of Chlorine Needed to Produce Hydrochloric Acid

To calculate the amount of chlorine needed to produce a certain quantity of hydrogen chloride, we can use the balanced chemical equation for the reaction between chlorine and hydrogen:

Cl2 + H2 → 2HCl

Given that the quantity of hydrogen chloride is 5 moles, we can use the stoichiometry of the reaction to determine the amount of chlorine required.

According to the balanced chemical equation, 1 mole of chlorine reacts with 1 mole of hydrogen to produce 2 moles of hydrogen chloride. Therefore, the amount of chlorine required can be calculated as follows:

Number of moles of chlorine = (Number of moles of hydrogen chloride) / 2

Substituting the given value: Number of moles of chlorine = 5 / 2 = 2.5 moles

Calculating the Mass of Chlorine

To calculate the mass of chlorine required, we can use the molar mass of chlorine, which is approximately 35.5 g/mol.

Using the formula: Mass = Number of moles × Molar mass

Substituting the values: Mass of chlorine = 2.5 moles × 35.5 g/mol = 88.75 grams

Therefore, the mass of chlorine required to produce 5 moles of hydrogen chloride is approximately 88.75 grams.
