The fundamental law is that 'matter can neither be created or destroyed in a chemical reaction'. This means that there has to be the same amount of matter on either side of the chemical equation, arranged differently, but the same number of atoms of each element involved in the reaction.

Why balanced equations for Stoichiometry to work?
You must balance chemical equations out before converting because if you don't, you will write down a wrong mole value somewhere along the line when you convert between units.
Chemical equations must be balanced because of the?
little boys
Why must chemical equations must be balanced?
chemical equations must be balanced according to the law of conservation of mass: mass cannot be created or destroyed. In other words: it's impossible to have an unbalanced equation that is correct, so do what your teacher tells you to.
Why should chemical equation be balance?
According to Law of conservation of mass - The mass of matter can neither be created nor be destroyed. So, th no. of mass in reactants and products in chemical eequation should be same. To satisfy this Law chemical equation should be balance.
Which law physical science must be followed when balancing chemical equations?
the law of conservation of mass
Chemical equations must be?
balanced.
Why balanced equations for Stoichiometry to work?

What is some advice for solving systems of equations?
Always keep the equation in balance inasmuch that what is done on the RHS must be done on the LHS of the equation.
Why must you balance equations?
To establish the law of conservation of mass.
Is chemical equations required to be balanced?
Yes, chemical equations must be balanced due to the law of conservation of matter/mass.
Which do you use to balance equations subscrips or coefficients?
Both. you must have the correct subscripts to represent the correct chemical then you only change the coefficients to balance the equation. The product of a coefficient and a subscript tells how many atoms are present.
Why is it essential to use balanced chemical equations when determining the quantity of a product fo?
It should represent a true chemical change. It should be balance it should be molecular all the reactant and product must be written in term of there respective chemical formula.

How do you balance a combustion reaction?
Combustion reaction equations balance the same way that any other chemical equation does. Every atom that appears on the left side of the equation must also appear on the right side of the equation. No atoms are created or destroyed in the process of a chemical reaction.
What is true about balanced equations?
The amount on one side of the '=' must balance the amount on the other.
Why is it wrong to change subcripts when balancing chemical equation?
When you are balancing known reactants and known products which is always the case when you are asked to "balance" a chemical equation you must not change the subscripts as that changes the reactants or the products to a different chemical compound.
What des a chemical equation stand for?
chemical equations are used to find out how chemical compounds will react with each other since the equations must be balanced. unless you are talking about the chemical name for substances such as sodium chloride is NaCl. water is H2O etc.
