Answer: 1) 20.0L NH3 @ STP (for 2022 students 11.4 grams) 2) 23.9g Fe2O3 3) 0.252g CaO
Answer the following problems showing all appropriate work and Using Mole Wheel in your folder.
1) How many liters (2021-2022 use grams) of NH3 are needed to react completely with 30.0L of NO in the following chemical reaction. Assume all gases @STP.
4 NH3 (g) + 6 NO(g) --> 5 N2 (g) + 6 H2O(g)
2) How many grams of Fe2O3 are formed when 16.7g of Fe reacts completely with oxygen?
4 Fe(s) + 3 O2 (g) --> 2 Fe2O3 (s)
3) How many grams of calcium oxide do I need to react to obtain 0.905g of Hg as described by following reaction.
4 HgS(s) + 4 CaO(s) --> 4 Hg(l) + 3 CaS(s) + 1 CaSO4 (s)
Answer: 1) 20.0L NH3 @ STP (for 2022 students 11.4 grams) 2) 23.9g Fe2O3 3) 0.252g CaO
