solid sodium reacts with water to give aqueous sodium hydroxide and hydrogen gas. a.) write a balanced equation for the reaction b.) calculate the "change in h"(little triangle next to big h), for the reaction c.) how many grams of sodium have reacted if 405 kj of energy is released when this reaction is run? d.) in a separate reaction of sodium with water 6.50 l of hyrogen gas is produced at 740 mm hg and 17 degrees celsius. what volume would this sample of hydrogen gas occupy at stp?
