Answer: nitrogen and hydrogen
Explanation:
2NH3 —> N2 + 3H2
Answer:
4
Explanation:
Elements in group 14 have 4 valence electrons. Meaning that to achieve a stable octet they need to either gain or lose 4 electrons in total.
(a) <u>7.32 moles of N₂</u>
(b) = 5.72 moles of NO
(c) 0.460 moles of O₂
Explanation:
We begin by balancing the chemical reaction involved;
N₂ + 0₂ → 2NO
The number in front of the elements or compounds indicate the mole ration involved in the reaction. One (1) mole of N2 and one (1) mole of O2 react to form two (2) moles of NO.
(a) Because the mole ratio between O₂ and N₂ is 1 : 1 then <u>7.32 moles of N₂</u> are needed to react with 7.32 mol of O₂
(b) Because the ration of N₂ and NO in the chemical equation is 1 : 2, then (2.86 * 2) moles of NO can be formed when 2.86 mol of N₂ reacts.
= 5.72 moles of NO
(c) (b) Because the ration of O₂ and NO in the chemical equation is 1 : 2, then (0.230 * 2) moles of O₂ must react to produce 0.230 mol of NO.
= 0.460 moles of O₂
