Calcium (Ca) is element.
O2 and CaO are molecules.
Calcium, Ca, and oxygen, O2, are elements (first is mono-atomic, the second is diatomic). Calcium oxide, CaO, is a molecule made of two elements.
AB + C + B is not an equation: an equation requires two sets of compounds on either side of an equality sign. Furthermore, it cannot be any of the following types of reactions because there is nothing following.

Calcium, Ca, and oxygen, O2, are elements (first is mono-atomic, the second is diatomic). Calcium oxide, CaO, is a molecule made of two elements.
Yes, the elements in the equation 2Ca (s) + O2 (g) → 2CaO (s) are calcium (Ca) and oxygen (O). Calcium is a solid (s), and oxygen is a gas (g) in their elemental forms. The product, calcium oxide (CaO), is also a solid. This reaction represents the combination of calcium and oxygen to form calcium oxide.
The equation is:CaCO3.......................→CaO + CO2

Solve the following equation for A : 2A/3 = 8 + 4A
undefined.
A plus sign in an equation is used to indicate addition. It shows that elements or terms are being combined to find the sum.
(x+9)(x+4)
-2x plus 3y equals 1

The slope of the line that represents the graph of that equation is 15.
AB + C + B is not an equation: an equation requires two sets of compounds on either side of an equality sign. Furthermore, it cannot be any of the following types of reactions because there is nothing following.
