Nitrogen gas reacts with hydrogen to produce ammonia. Use the chemical equation to complete the statements. N2 + 3H2 → 2NH3 There are nitrogen atoms on the product side. There are hydrogen atoms on the reactant side.

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.

it would be b. 6co2 + 6h2o --> c6h12o6 + 6o2
