Answer:
Q = 0.144
Explanation:
- C(s) + H2O(g) ↔ CO(g) + H2(g)
reaction quotient:
- Q = [H2(g)][CO(g)] / [H2O(g)][C(s)]
∴ [C(s)] = 10.0 mol/2.50 L = 4 M
∴ [H2O(g)] = 16.0 mol/2.50 L = 6.4 M
∴ [CO(g)] = 3.30 mol/2.50 L = 1.32 M
∴ [H2(g)] = 7.00 mol/2.50 L = 2.8 M
⇒ Q = (2.8 M)(1.32 M) / (6.4 M)(4 M)
⇒ Q = 0.144

Answer:
92.6 g.
Explanation:
- The balanced equation is:
CaC₂ + N₂ → CaCN₂ + C.
- It is clear that 1.0 mole of CaC₂ reacts with 1.0 mole of N₂ to produce 1.0 mole of CaCN₂ and 1.0 mole of C.
- We need to calculate the no. of moles of 265.0 g of CaCN₂ produced using the relation:
n = mass / molar mass = (265.0 g) / (80.102 g/mol) = 3.308 mol.
- We should get the no. of moles of N₂ needed to produce 3.308 mol of CaCN₂.
∵ 1.0 mole of N₂ produces → 1.0 mole of CaCN₂.
<em>∴ 3.308 mole of N₂ produces → 3.308 mole of CaCN₂.</em>
- Now, we can get the grams of N₂ consumed to produce 265.0 g of CaCN₂:
∴ The grams of N₂ = n x molar mass = (3.308 mole)(28.0 g/mol) = 92.63 g = 92.6 g.
The coefficient of Fe would be 2, the coefficient of Cl2 would be 3, while the coefficient of FeCl2 would be 2.
The balanced equation of the reaction would be as follows:
Thus, the coefficients of Fe, Cl2, and FeCl3 respectively would be 2, 3, and 2.
In other words, 2 moles of Fe require 3 moles of Cl2 to produce 2 moles of FeCl3 in a complete reaction.
