A student did an experiment to find the amount of energy produced when
hydrogen peroxide solution is decomposed using manganeso(IV) oxide. The
apparatus the student used is shown in the diagram.
Manganeso(IV) oxido
Thermometer
Beaker
-Hydrogen peroxide
2 point
The student first measured the temperature of the hydrogen peroxide.
Then the student added the manganese(IV) oxide and recorded the
highest temperature. The temperature rise was smaller than expected,
