Hydrogen H

_{2}reacts with oxygen O_{2}to produce water H_{2}O according to the following proportion:2 moles of H

_{2}react with 1 mole of O_{2}to produce 2 moles of H_{2}O (balanced equation)0.46 g of H

_{2}is 0.228 moles of H_{2}which are going to react with 0.114 moles of O_{2}(half the moles of H_{2}according to the above proportion) to produce 0.228 moles of H_{2}O (again, according to above proportion). You can check there is more than enough O_{2}to consume all of the H_{2}and there will be some O_{2}leftover.0.228 moles of water in grams is 0.228 mol * (18.02 g/mol) = you do the math (the result in grams)

Note: if you don't understand the concept of molar mass and proportions it will be hard for you to solve chemical reactions.
