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?

Which element in the third period would you expect to have the larger atomic radius, sodium (na) or sulfur (s)? a. sodium, because it has a higher effective nuclear charge attracting electrons in fewer energy levels. b. sodium, because it has fewer protons attracting electrons in the same energy levels. c. sulfur, because it has more protons attracting electrons in more energy levels. d. sulfur, because it has a higher effective nuclear charge attracting electrons in the same energy levels.
