Hydrochloric acid reacts with calcium to form hydrogen and calcium chloride. if 100 grams of hydrochloric acid reacts with 100 grams of calcium, what is the limiting reactant? 2hcl ca → cacl2 h2 calcium hydrogen calcium chloride hydrochloric acid

hydrochloric acid

Explanation:

As can be seen from the chemical equation, 2 moles of hydrochloric acid react with 1 mole of calcium.

According to mole concept, 1 mole of every substance weighs equal to its molar mass.

Thus of of hydrochloric acid reacts with 40 g of calcium.

100 g of hydrochloric acid react with=of calcium

Thus HCl is the limiting reagent as it limits the formation of product and calcium is the excess reagent as (100-54.79)=45.21 g is left unreacted.

no but i do not usually comment or use my voice that much when it comes to social media

the answer is a and have a great day
