Answer 2

Hydrogen Production from Magnesium and Hydrochloric Acid

To calculate the amount of hydrogen gas produced when 8g of magnesium is dissolved in hydrochloric acid, we can use the balanced chemical equation for the reaction between magnesium and hydrochloric acid:

Mg + 2HCl → MgCl2 + H2

According to the stoichiometry of the balanced chemical equation, 1 mole of magnesium reacts with 2 moles of hydrochloric acid to produce 1 mole of hydrogen gas.

First, we need to calculate the number of moles of magnesium in 8g of magnesium using the formula:

moles = mass / molar mass

The molar mass of magnesium (Mg) is approximately 24.305 g/mol.

So, moles of magnesium = 8g / 24.305 g/mol = 0.329 moles

Since 1 mole of magnesium
