This is called thermal decomposition. CaCO₃ decomposes into calcium oxide (CaO) and Carbon Dioxide (CO₂).

Oxidation is the loss of electrons from a molecule, atom, or ion. This corresponds to an increase in the oxidation number of the molecule, atom, or ion.

Atoms involved in a covalent bond will share ​a pair of electrons in order to acheive a full outer shell in both atoms. Each atom will donate a single electron to the ...

Sulfer, when burned in the presence of oxygen, will form sulfer dioxide (SO₂​). This can then dissolve in rain water, forming sulfuric acid. This will then fall to the ground as acid rain wh...

1)Always write out the reaction first;

2NaCl+CaCo3-->Na2Co3+CaCl2  

2)Now underneath calculate the Relative Formula Mass using a periodic table for each of the compounds....
