The balanced chemical equation below shows the reaction between nitrogen (N2) and hydrogen (H2) to form ammonia (HN3). N2 + 3H2 → 2NH3

If 10.0 grams of nitrogen reacts with hydrogen to form 12.0 grams of ammonia, then how many grams of hydrogen were used in this reaction?

Calculate the estimated density of each ball. use the formula d = m/v where d is the density, m is the mass, and v is the volume. record your calculations in table a of your student guide. given that the density of water is 1.0 g/cm3, make a prediction about whether each ball will float in water. record your prediction in table a. what is the estimated density of the table tennis ball? record your answer to the nearest hundredth
