Without an equality sign the information given can't be considered as an equation
There is no "general" equation. The square root of a number (or expression) is simply sqrt(x) or x1/2, where x is a number or an expression. In more basic mathematics, x must be non-negative but, once you start studying complex numbers, that is no longer a requirement.

2b + d
A basic logarithmic equation would be of the form y = a + b*ln(x)
Revenue-expenses= profit or loss. Hope this helps!(:
the oxygen of the zinc will combine with acid group of the acid as the ZnOis basic in nature
When many were taught chemistry in the 1970s this was called a double decomposition reaction. It is now called a salt metathesis reaction and also double displacement reaction. There are examples and more information at the related link.
NaCN + H2O ---> CN-+ H3O++ Na+ In that equation Na+ is just a spectator ion,, further reaction with water results in: CN- + H2O ---> HCN + OH- thus causing the resulting equation to be basic
The balanced equation: C6H12O6 + 6O2 --> 6H2O + 6CO2 + energy The most basic, unbalanced equation is: C6H12O6 + O2 --> H2O + CO2
The rusting of iron is a chemical change, where iron and oxygen are the reactants and rust is the product. The basic equation for this reaction is: 4Fe + 3O2 --> 2Fe2O3

Equations should be balanced because of a basic scientific law known as the Law of Conservation of Mass. The Law simply means that all the mass you start with in a chemical reaction should be present at the end. Balancing the equation allows scientists to mathematically predict how much matter there should be at the end of a reaction.
Periodicity assumption.

This is called a neutralization reaction.
A basic equation for the formation of rust is 4Fe + 3O2 --> 2Fe2O3
