Initial answer - (which happens to be wrong - but has been kept because it illustrates a misunderstanding that you want to avoid):
has to have the same number of moles on both side because u cannot make or destroy moles
mmm ... not exactly
As an example, the combustion of hydrogen is 2H2 + O2 ==> 2H2O
In this example you could start with 3 moles (2 moles of H2 and 1 mole of O2) and wind up with 2 moles (of H2O).
The law that must be obeyed is "Conservation of mass". Using the example above, you start with 4 hydrogen atoms and 2 oxygen atoms in the reactants and end with 4 hydrogen atoms and 2 oxygen atoms in the products. The mass is conserved.

By the way, the conservation of (the kind and number of) elements and charge is also satisfied.

∙ 8y agoIn a chemical equation the Law of Conservation of Mass is followed. Another, less known law called the Law of Conservation of Charge is also followed.When balancing a chemical equation you must make sure that there are the same number of each element on each side of the equation. For example in the Equation C6H12O6 + 6O2 => 6CO2 + 6H2O There are six carbons, 18 oxygens, and 12 hydrogens on each side of the equation. This makes both sides of the equation have equal mass.You must also make sure that the total charge on each side of the equation is equal. For example in the equation 2H+ + CO32- => H2O + CO2 On the left side of the equation there is a 2*(+1) + (-2) = 0 charge and on the right side of the equation there is also a total of 0 charge. This makes both sides have an equal charge of 0 so the law of conservation of charge is also followed.

Which is chemical equation?
A chemical Equation is a shorthand form of a chemical reaction. chemists use it to help them tell the substances that are present such as reactants, products, or proportions.Some equations also tell the physical state of a substance.
Is a change that produces a new element a physical change?
No, it is a chemical change. ---------------------------------- Yes, it is a physical change because this change not involve a chemical reaction but a nuclear reaction followed by a change in the number of protons and neutrons.

What symbolic representation of a chemical reaction?
There are several things that may symbolize a chemical reaction. One of the main symbols is a chemical equation which will represent the entities in the reaction. .
Is mixing acid with base a chemical or physical change?
Adding a base to an acid or vice versa in changing the chemical properties of that solution. In both cases you are neuralizing the solution. There might be a physical change as well, but it would depend on what chemicals where mixing. But this reaction will definitely have a chemical change.
