Limiting Reagent

What is a limiting reagent? Explain.

In a reaction, \[\ce{A + B2 -> AB2}\]

Identify the limiting reagent, if any, in the following reaction mixture.

2.5 mol A + 5 mol B

Calcium carbonate reacts with aqueous \[\ce{HCl}\] to give \[\ce{CaCl2}\] and \[\ce{CO2}\] according to the reaction given below:

\[\ce{CaCO3(s) + 2HCl (aq) -> CaCl2 (aq) + CO2(g) + H2O (l)}\]

What mass of \[\ce{CaCl2}\] will be formed when 250 mL of 0.76 M \[\ce{HCl}\] reacts with 1000 g of \[\ce{CaCO3}\]? Name the limiting reagent. Calculate the number of moles of \[\ce{CaCl2}\] formed in the reaction.

Explain the term molarity
