Answer 1

The number preceeling en chemical equation moles - A the formulas are referred you a compound to as the a for be N₂ + 3H₂ → 2NH3 one more of N react with three more of H, to Enduce a more of ammonia. - The actual yield of a chemical reaction is calculated by multiplying ito limiting reagent by molecular weight of the product." - B Actual field can be found by - no. of moles of limiting enagent & no. almole al u product y no. of mole of limiting smaget x moliwego C4 ALU (63) .
