Answer 1

To find the solubility of NH3 gas at various temperatures, we can refer to solubility data, typically provided in laboratory tables. Since I don’t have access to such an explicit table right here, I can guide you through matching the values based on your options provided.

From typical solubility data:

1. At **0°C**, the solubility of NH3 is generally around **1000 g NH3/kg water** (option b).
2. At **10°C**, the solubility of NH3 is typically around **900 g NH3/kg water** (option d).
3. At **30°C**, the solubility is around **700 g NH3/kg water** (option a).
4. At **50°C**, the solubility is around **600 g NH3/kg water** (option c).

Putting that all together, we can match the values:

1. The solubility of NH3 gas at **30°C** - **a. 700 g NH3 gas/kg Water**.
2. The solubility of NH3 gas at **10°C** - **d. 900 g NH3 gas/kg Water**.
3. The solubility of NH3 gas at **50°C** - **c. 600 g NH3 gas/kg Water**.
4. The solubility of NH3 gas at **0°C** - **b. 1000 g NH3 gas/kg Water**.

### Summary:
- For Column A, the answers are:
1. b: 1000 g NH3 gas/kg Water
2. d: 900 g NH3 gas/kg Water
3. c: 600 g NH3 gas/kg Water
4. a: 700 g NH3 gas/kg Water
