Use your balanced reaction to make a "for every" statement for magnesium and hydrochloric acid in this reaction A: For every 1 mol of magnesium, the reaction makes 1 moles of hydrochloric acid.

B: For every 24.305 mol of magnesium, the reaction uses up 34.46 mol of hydrochloric acid,

C: For every 1 mole of magnesium, the reaction uses 2 moles of hydrochloric acid.

D: For every 1 mol of magnesium, the reaction uses 1 mol of hydrochloric acid.

Right answer is C.

Explanation:

Based on the reaction with magensium, Mg, and hydrochloric acid, HCl:

Mg + 2HCl → MgCl₂ + H₂

The reaction is balanced in moles therms

We can see that 1 mole of Magnesium is reacting with 2 moles of HCl to produce 1 mole of MgCl₂ and 1 mole of H₂. In another words:

For every 1 mole of magnesium, the reaction uses 2 moles of hydrochloric acid.

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.
