Given the following equation: Zn+2HClarrow H_(2)+ZnCl_(2) How many moles of HCl are needed to react with 0.50 moles of zn? a. 0.75 moles b 0.50 moles c 1.25 moles d 1.0 mole 0.25 moles

## Step 1: Identify the balanced chemical equation for the reaction. The equation is already balanced and given as: ### ## Step 2: Understand the stoichiometric ratios of reactants from the balanced chemical equation. According to the equation, for every 1 mole of Zn, you need 2 moles of HCl.## Step 3: Calculate the required moles of HCl for the given moles of Zn. Since we need twice as many moles of HCl for every mole of Zn, for 0.50 moles of Zn, we need moles of HCl.
