The following balanced equation shows the formation of water. 2H_(2)+O_(2)arrow 2H_(2)O How many moles of oxygen (O_(2)) are required to react completely with 1.67 mol H_(2) i 0.835molO_(2) 1.67molO_(2) 3.34molO_(2) 6.68molO_(2)

The balanced chemical equation given is: This equation tells us that 2 moles of hydrogen gas ( ) react with 1 mole of oxygen gas ( ) to produce 2 moles of water ( ).To find out how many moles of are needed to react with moles of , we use the mole ratio from the balanced equation, which is .So, for every 2 moles of , we need 1 mole of . If we have moles of , we need half of that amount in moles of because the ratio is 2:1. Therefore, moles of oxygen ( ) are required to react completely with moles of hydrogen ( ).
