The number of molecules
CPUs, when given mathematical equations, apply the laws of mathematics to those equations. The equation a = a is true by the reflexive property of equality.
It means that there is no set of values for the variables such that all the linear equations are simultaneously true.
Yes.
Yes, chemical equations must be balanced due to the law of conservation of matter/mass.
False. Chemical equations are balanced by changing the coefficients in front of the chemical formulas, not the subscripts within the formulas. The number of atoms of each element must be equal on both sides of the equation to ensure that mass is conserved.
In a balanced chemical equation, the number of atoms of each element on both the reactant and product sides are equal, ensuring the law of conservation of mass is satisfied. This balance signifies that no atoms are created or destroyed during a chemical reaction, but instead rearranged.
Mole Ratios
Both balanced and unbalanced chemical equations represent the chemical reactions that take place between reactants to form products. The key difference is that balanced equations have an equal number of atoms of each element on both sides, while unbalanced equations do not.
Conservation of mass.

Some examples of unbalanced equations include: CH4 + O2 -> CO2 + H2O (the number of oxygen atoms is not balanced) Mg + HCl -> MgCl2 + H2 (the number of chlorine atoms is not balanced)
Properly balanced equations are necessary in chemistry to accurately represent the conservation of mass and atoms in a chemical reaction. Balanced equations ensure that all reactants are accounted for and that the number of atoms remain the same on both sides of the reaction.

They are necessary for accurate chemical calculations.
