How many moles of hydrochloric acid react with zinc?

You are correct if you thought the answer was one. One mole of zinc will react with 2 moles of aqueous hydrogen chloride to form one mole of zinc chloride and one mole of hydrogen gas. Question: If you started this reaction with 65 grams of zinc, how many grams of hydrogen would you expect to make?

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?

1 Expert Answer

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?

The HCl (hydrochloric acid) contributes one mole of chlorine to the NaCl and a mole of Hydrogen to the H2O. So the same amount of HCl as NaOH (one mole) is required.

What happens if hydrochloric acid reacts with zinc?

When zinc reacts with hydrochloric acid it produces zinc chloride and hydrogen gas.

How many moles reacted with zinc?

One mole of zinc will react with 2 moles of aqueous hydrogen chloride to form one mole of zinc chloride and one mole of hydrogen gas.

How many moles of hydrogen are produced from the reaction of 3.0 moles of zinc with an excess of 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 grams of zinc chloride are formed?

Zinc is the limiting reactant, and 6.81g of zinc chloride is produced.

What is the maximum grams of zinc chloride?

2 moles of hydrochloric acid produces 1 mole of zinc chloride. So,0.087 moles of hydrochloric acid produces = of zinc chloride. Putting values in equation 1, we get: Hence, the mass of zinc chloride formed will be 5.928 grams.

How many moles are required to react with moles?

Determine the number of moles needed to react by multiplying by moles of the known substance by the stoichiometric ratio of the unknown substance to the known substance.

What is the molar mass of zinc?

Molar mass is defined as the mass of one mole of representative particles of a substance. By looking at a periodic table, we can conclude that the molar mass of lithium is 6.94g, the molar mass of zinc is 65.38g, and the molar mass of gold is 196.97g.

How do you calculate the number of moles needed?

Determine the moles of product produced by dividing the grams of product by the grams per mole of product. You now have calculated the number of moles of every compound used in this reaction.

Why does zinc corrode in hydrochloric acid?

The corrosion of zinc in an oxygenated hydrochloric acid electrolyte illustrates the effect of multiple cathodic reactions. Whatever the cathodic reaction, the anodic reaction is always the oxidation of zinc: Zn -> Zn2+ + 2e. Zinc is a metallic conductor and electronic transfer to its cathodic regions is facile.

Does zinc dissolve in hydrochloric acid?

Example. Will Zinc metal readily dissolve when added to HCl? Adding the two half-reactions together gives the overall equation and a positive value for E. This means the reaction is spontaneous and Zn will dissolve in HCl.

What is the ionic equation for zinc and hydrochloric acid?

The reaction between zinc and HCl is given by the symbolic equation Zn + HCl → ZnCl2 + H2. Note that H2 is hydrogen gas.
