Expert Solution
Step 1

The weight of sample is 1.569 g.

The given temperature values are 23.97 ˚C and 30.72 ˚C.

The constant value for specific heat is 42.31 kJ/g ˚C.

Step 2

The heat transfer during a reaction is given by,

Chemistry homework question answer, step 2, image 1

The temperature has increased, which means reaction is an exothermic reaction. Therefore,

Chemistry homework question answer, step 2, image 2

Step 3

Here, q is the heat energy, m is the mass of a substance, c is the specific heat, and ∆T is the change in temperature.

The change in temperature is,
