The equation shows the reaction between zinc metal and hydrochloric acid. zn(s) + 2hcl(aq) mc014-1.jpg zncl2(aq) + h2(g) what is the theoretical yield of hydrogen gas if 5.00 mol of zinc are added to an excess of hydrochloric acid? a.5.05 g b.10.1 g c.182 g d.682 g

10 grams of Hydrogen gas will be produced theoretically.

Explanation: The equation for the reaction between zinc metal and hydrochloric acid is:

As HCl is present in excess, therefore limiting reagent is Zinc metal as it limits the formation of product.

By stoichiometry,

1 mole of Zinc metal produces 1 mole of Hydrogen gas, therefore

Amount of Hydrogen gas produced can be calculated by:

Molar mass of Hydrogen = 2 g/mol

Mass of hydrogen gas produced = (5 moles )× (2 g/mol)

Mass of hydrogen gas produced = 10 grams

b. acid is the correct answer @jayxboof all social media

acid : acids are those which accepts an electron-pairs.

base : bases are those which donates ab electron-pairs.

alkali : it is a base that dissolves in water. it is basically a base and the ph greater than 7.

hydroxide ion : it is a poly-atomic ion which is negatively charged.

thats how its supposed to be
