Answer: 218.4 g of CaO will be produced from 3.9 moles of CaCO_3

Explanation:

The balanced chemical equation is:

CaCO_3\rightarrow CaO+CO_2  

According to stoichiometry :

1 mole of CaCO_3 produce =  1 mole of CaO

Thus 3.9 moles of CaCO_3 will produce=\frac{1}{1}\times 3.9=3.9moles of CaO

Mass of CaO=moles\times {\text {Molar mass}}=3.9moles\times 56g/mol=218.4g

Thus 218.4 g of CaO will be produced from 3.9 moles of CaCO_3

Answer:

It is true that earth was once covered with oceans and little dry land.

Explanation:

Over the course of around four billion years, the Earth's oceans have lost about a quarter of their original mass. Today the atmosphere is rich in oxygen, which reacts with both hydrogen and deuterium to recreate water, which falls back to the Earth's surface. So the vast bulk of the water on Earth is held in a closed system that prevents the planet from gradually drying out. According to the researchers,  the continents emerged relatively suddenly from an ocean that covered 95 percent of the Earth's surface. The appearance of large masses of dry land would have caused more extreme weather, changes in ocean currents and the emergence of proper seasons. In turn, these environmental changes may have led to rise in atmospheric oxygen that enabled the explosion of new life forms around 500 million years ago.
