the mass of water in grams formed by the reaction when 11.2 L of H 2 reacts with 5.6 L of O 2
Dear student H2 + ½ O2 --------> H2O hence 11.2 mole water forms or ½ mole hence ½ = w / 18 w = 9 gm hpe it helps
22.4 L = 1 mole so mole of H2 = ½ moe of O2 = 1/4then complete H2 and O2 react to form ¼ mole of waterso mass of water = 18/4 = 4.5 gmHope it clears.
We very well know the reaction 2H2 + O2 = 2H2O. It is balanced.We can see that 2 moles of H2 and 1 mole of O2 combine to form 2 moles of water.Let us convert the given information into moles.11.2 Litres is 0.5 moles5.6 Litres is 0.25 moles.According to reaction 2 + 1 gives 2We have, 0.5 + 0.25 which must give 0.5 moles of H2O. Thus, the answer is 9 grams. Regards, M.S.R
