Helen [10]3 years ago

Mass, charge, and energy are conserved, no matter how much volume of
space they may be spread through either before or after the reaction.

Concerning density ...
Think about the fascinating classroom demonstration where the teacher
drops a tiny pellet of sodium into a glass of water.  The sodium gets very
excited, and it skates and skitters around on the surface of the water,
faster and faster, and eventually it explodes.  All the girls in the class
scream, while the guys are just sitting there and staring at the cloud
of steam that's rising from the glass of water.  The whole point here
is that the density of the steam is much different from the density of
either the water or the sodium that reacted to create it.  The density
is not conserved.

Answer:

The yearly release of CO_2 into the atmosphere is 6.73\times 10^{10} kg.

Explanation:

CaCO_3(s)\rightarrow CaO(s) + CO_2(g)

Annual production of CaO = 8.6\times 10^{10} kg=8.6\times 10^{13} g

Moles of CaO :

\frac{8.6\times 10^{13} g}{56 g/mol}=1.53\times 10^{12} moles

According to reaction, 1 mole of CaO is produced along with 1 mole of carbon-dioxide.

Then along with  1.53\times 10^{12} moles of CaO moles of carbon-dioxide moles produced will be:

\frac{1}{1}\times 1.53\times 10^{12} moles=1.53\times 10^{12} moles of carbon-dioxide

Mass of 1.53\times 10^{12} moles of carbon-dioxide:

1.53\times 10^{12}mol\times 44 g/mol=6.73\times 10^{13} g =6.73\times 10^{10} kg

The yearly release of CO_2 into the atmosphere is 6.73\times 10^{10} kg.
