c.
Explanation:
Hello,
Due to the fact that an odorless gas was released, the chemical reaction between lithium carbonate and a random acid (for instance hydrochloric acid) turns out into:
It is known that carbonic acid is unstable and it quickly decomposes into water and carbon dioxide which is an odorless gas. In spite of the fact that the releases
it isn't the solid since that gas is odorous.
Best regards.
1. O2 is the limiting reagent
2. Excess NH3 = 0.102 moles
3. 0.088 mol of NO is formed
4. 2.376 grams of H2O is formed
<h3>Stoichiometric problem</h3>From the equation:
Mole ratio of NH3 and O2 = 4:5
Mole of 3.25 g NH3 = 3.25/17 = 0.19 mol
Mole of 3.50 g O2 = 3.5/32 = 0.11 mol
Equivalent mole of O2 from NH3 = 5/4 x 0.19 = 0.24 mol
Equivalent mole of NH3 from O2 = 4/5 x 0.11 = 0.088 mol
Thus, O2 is the limiting reagent.
Excess NH3 = 0.19 - 0.088 = 0.102 moles
Mole ratio of O2 and NO = 5:4
Equivalent mole of NO = 4/5 x 0.11 = 0.088 mol
Mole ratio of O2 and H2O = 5:6
Equivalent mole of H2O = 6/5 x 0.11 = 0.132 mol
Mass of 0.132 mol H2O = 0.132 x 18 = 2.376 grams
