Question

select sucrose from the list of compounds and adjust the mass of the compound to 380 mg. set the mass of water in the calorimeter to 1000 g and press ignite. by how much did the temperature change? the heat capacity of the calorimeter vessel is 420 j/°c. the temperature changed from 20.00 °c to 22.87 °c.

Explanation:

Step1: Identify initial and final temperatures

Initial temperature $T_1 = 20.00^{\circ}C$, final temperature $T_2=22.87^{\circ}C$.

Step2: Calculate temperature change

The formula for temperature change $\Delta T=T_2 - T_1$. So, $\Delta T=22.87 - 20.00=2.87^{\circ}C$.

Answer:

$2.87^{\circ}C$
