# Frequent question: How many moles of hydrochloric acid react with zinc?

Contents

## How many moles of HCl are required to react with all the zinc?

By the stoichiometry of the reaction, each zinc particle requires 2 hydrochloric acid particles (i.e. each equivalent of zinc metal requires 2 hydrochloric acid particles). Thus 0.2 mol of zinc metal were required.

## How many moles of zinc chloride will hydrochloric acid produce?

And in this case hydrochloric acid is the limiting reactant because it produces 2.5 moles of zinc chloride whereas zinc produces 5 moles of zinc chloride.

## How many moles of HCl are required for the reaction?

Problem: How many liters of SO2 will be produced from 26.9L O2?

## How many moles of fe2s3 are produced when 2 moles of Fe react with 3 moles?

Because the equation is balanced, we know the proportions of iron and sulfur in the reaction. For this reaction, we see that 2 moles of iron reacts with 3 moles of sulfur to form 1 mole of iron(III) sulfide.

## What number of moles of H2 are released when 3 moles of Zn completely react with HCl?

As per the balanced chemical equation, 1.0 mole of zinc reacts with HCl to produce 1.0 mole of hydrogen gas. Therefore, the number of moles of hydrogen gas produced from the reaction of 3.0 moles of Zn is 3.0 moles.

## How many moles are in zinc?

For the rest of the atoms on the periodic table, their molar mass tells you how many grams of each you need to have a mole of those atoms, or 6.02×1023 atoms of that element. If zinc has 1 mole, it will have 6.02×1023 .

## How do you do Stoich?

Almost all stoichiometric problems can be solved in just four simple steps:

1. Balance the equation.
2. Convert units of a given substance to moles.
3. Using the mole ratio, calculate the moles of substance yielded by the reaction.
4. Convert moles of wanted substance to desired units.
