Kindly guide this through Sir Ali Miraj Method? Consider the given balanced chemical equation: 2H2+O2→ 2H2O If 4g of H2 reacts with 32g of O2 to produce 28 g of H₂O, what is the percentage yield of the reaction? (Molar mass of H2 = 2 g/mol, O2 = 32 g/mol and H2O = 18 g/mol) a) 63.6% b) 77.8% c) 87.5% d) 92.5%

I'm actually unaware of Sir's method; I'll still try to help you get it.

Plz reply me I am not able to post plz plz i cannot solve this question plz guide me its a humble request am i right regarding my cocept that first we find limiting reacting according to question and the amount that is low is actual yeid than we divide it by theoretical yeild 28 bcz it is high ? Whenever I use chatgpt they said both h2 and o2 have same mole But I am confused or gpt say in question produced is written do it is actual yeild plz guide me

As the amounts of reactants needed (according to the balanced equation) and those given (in the problem) are equal, there's no limiting reactant. By dividing the actual yield (28; given) with the theoretical yield (2x18; got from the balanced equation), we get 28\36=0.63 making (A) the correct option.
