Answer 1

To fill in the missing amounts of NH4Cl that can dissolve at different temperatures, you would typically refer to a solubility chart. The solubility of NH4Cl at various temperatures is as follows:

1. At 0°C, d. 17 grams of NH4Cl will dissolve in 100 grams of water.
2. At 30°C, f. 41 grams of NH4Cl will dissolve in 100 grams of water.
3. At 50°C, j. 30 grams of NH4Cl will dissolve in 100 grams of water.
4. At 80°C, a. 65 grams of NH4Cl will dissolve in 100 grams of water.

So the completed columns would read:
