Calculate the heat absorbed by water and the heat of combustion of sulphur given the mass of water, specific heat capacity of water, and the temperature change.

Here are the solutions to your chemistry assignment questions:

1. Calculation of Heat of Combustion of Sulphur

Step 1: Calculate the mass of water.
Assuming the density of water is $1 \text{ g/cm}^3$:

$$m_{\text{water}} = 500 \text{ cm}^3 \times 1 \text{ g/cm}^3 = 500 \text{ g} = 0.500 \text{ kg}$$

Step 2: Calculate the heat absorbed by water ($Q$).

$$Q = m_{\text{water}} \times c_{\text{water}} \times \Delta T$$ $$$$
