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.

A basic logarithmic equation would be of the form y = a + b*ln(x)
Revenue-expenses= profit or loss. Hope this helps!(:
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
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.
The half reaction for the given chemical equation 2CO + O2 -> 2CO2 is: 2CO -> 2CO2 (in acidic medium) 2CO -> 2CO2 + 2H2O + 2e- (in basic medium)

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
The chemical reaction for rusting steel is: 4Fe (s) + 3O2 (g) -> 2Fe2O3 (s). This equation shows that iron reacts with oxygen in the presence of water to form iron oxide (rust).
A skeleton equation shows the correct formulas of the reactants and products but does not have balanced coefficients. It provides a basic outline of the chemical reaction without specifying the exact amounts of each substance involved. Balancing the equation ensures that the number of atoms of each element is the same on both sides of the reaction.

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.

Reactants are the starting materials that are present before a chemical reaction occurs, whereas products are the substances that are formed as a result of the reaction. You can identify reactants and products by examining the chemical equation that represents the reaction, with reactants typically positioned on the left side of the equation and products on the right side.
