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.
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
44
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.
2VdV + 2PdP + 3T2dT (this is an expression, not an equation because there is no equals sign)
