The amount of energy released is calculated by the product of heat of fusion and mass.
The formula of amount energy released is given by:
(1)
Here,
q is amount of energy released
L is heat of fusion (
)
m is mass of water
Put all the given values in equation (1)
≅ 
Thus, amount of energy released is 
Answer:
Climate changes and earthquakes are B.effects of evolution
Explanation:
Climate change consists of variations in the state of the weather and earthquakes (earth tremors) are due to the movement of tectonic plates. Both have existed since the formation of the Earth, due to a variety of natural circumstances, of man (for example, global warming generates climate change).
The most abundant carbon isotope is carbon-12.
The relative atomic mass of carbon is 12.011, which is extremely close to 12.0. This means that the masses C-13, and C-14 are practically negligible when contributing to the relative atomic mass of carbon.
the C-12 isotope makes up 98.9% of carbon atoms, C-13 makes up 1.1% of carbon atoms, and C-14 makes up just a trace of carbon atoms as they are found in nature.
The sum of the masses of the reactants is equal to the sum of the masses of the products.
Air is a poor conductor of sound.
