Question

in a reaction A+B2-AB2 identify limiting reagent when A is 5 mole and B is 2.5 mole​

Answer 1

Explanation:

According to the reaction, 1 mol of atom A combines with 1 mol of molecule B. Thus, 2.5 mol of A will combine with only 2.5 mol of B and the remaining 2.5 mol of B will be left as such. Hence, A is the limiting regent
