A chemical equation is the representation of a chemical reaction.
Chemical formulas of reactants and products; number of molecules involved in the reaction.
No, NaCl H2O is not a chemical equation. An equation must have an equal sign. And even if you put an equal sign into those terms, it is not true that NaCl = H2O, so that would be a false equation, not a complete and balanced equation. You are not even close to having that.
Examples: NaCl, H2, =, +, ----------------->, ↔, (s), etc.
Mole Ratio :)
That depends on the specific equation. The general idea is to "isolate" the variable, for example "x", manipulating the equation in such a way that all terms that contain "x" are on the left, and all terms that don't contain it, are on the right.
There are two terms: 3x, -2b. Yeah, two terms. But where is the equation?
element product atom
In algebraic terms, the solution is the answer to equation.
oxidation in molecular terms, but in more general terms, combustion, aka burning!
Chemical reactions are described based on observations. It may be in terms of changes in color, state of matter, or density.
An equation is a collection of terms that equal another collection of terms An expression is just a collection of terms that sometimes can be simplified
reactants-----> products
