What is the balanced chemical equation and type of chemical reaction of solid calcium oxide and sulfur dioxide gas react to form solid calcium sulfite?

1. CaO + SO2 —> CaSO3

2. Synthesis reaction

Explanation:

CaO + SO2 —> CaSO3

From the above we see that the equation is balanced as the numbers of atoms of the different elements on the left side are the same on the right side

The reaction is a synthesis reaction as the two reactants combine to form only one product

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.
