Answer : C
Explanation:
a star produces energy by combining two atoms into one creates a powerful burst of energy
<u>Answer:</u> The amount of heat released is 462.3 kJ
<u>Explanation:</u>
The chemical equation for the reaction of manganese and oxygen to produce manganese (II,III) oxide follows:
We need to calculate the amount heat released for 1 mole of manganese.
To calculate the amount of heat released, we use unitary method:
When 3 moles of manganese is burnt, the amount of heat released is 1387 kJ
So, when 1 mole of manganese is burnt, the amount of heat released will be =
Hence, the amount of heat released is 462.3 kJ
Chemical energy turns into heat and light energy.
There’s energy stored(potential) in the log, so when it burns, that energy is released as light and heat
