A solid is added to water. the temperature of the water rises from 18°C to 22°c. what type of change does this indicate?

3. Give two examples of substances which are soluble in water

If water evaporates can you see the solid particles of the drink mix?

For the solution containing Zn2 + (aq), n is 2, so the MM/n ratio will be the molar mass of Zn divided by 2: MM/n = (65.39 g/mol) / 2 = 32.70 g/mol Compare this theoretical value with your experimental result.
