Question

in a reaction A+B2 AB2 identify the limiting reagent if 300 atoms of A react with 200 molecules atoms of B​

Answer 1

Answer:

300 atoms of A + 200 molecules of B: 300 atoms of A will react with 200 molecules of B leaving at least 100 atoms of A unreacted. Here, B is the limiting reagent. (ii) 2 mol A + 3 mol B: In this reaction, 1 molecule of A reacts with 1 molecule of B. hence, 2 molecules of A will react with 2 molecules of B.Oct 25, 2018
