Which law of physical science mustbe followed when balancing chemical equations?
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.
Which is a balanced chemical equation according to the law of conservation of mass?
a balanced chemical equation according to the law of conservation of mass is that equation in which both the products side atoms are equal to the reactants side atoms.BEfore and after the chemical reaction.
How is law of conservation of mass shown by a balanced chemical equation?
In a balanced chemical equation, the number of atoms of each element are the same on both sides; they are just rearranged. This is due to the conservation of mass.
What particles must have an equal number on both sides of a chemical equation?
Due to the law of conservation of mass and matter, all particles must have an equal number on both sides of a chemical equation. An equal number of atoms of each element involved must be on each side of the equation.
How do you preserve the law of the conservation of mass in a chemical equation?
By making sure that the same numbers of each type of atom appear on both sides of the balanced equation for the reaction.

What two quantities are conserved in redox equations?
there is a conservation of mass and charge.

A chemical equation must be balanced to satisfy the law of what?
A balanced chemical reaction obeys the law of conservation of mass, because the same number of atoms of each element must appear on both sides of the equation for the reaction, and in any actual reaction, the same exact atoms will be found on both sides of the equation.
What principle can be applied to all chemical reactions?
material reacts in the presence of another material
What particles must have an equal number on both sides of a chemical equation?
Due to the law of conservation of mass and matter, all particles must have an equal number on both sides of a chemical equation. An equal number of atoms of each element involved must be on each side of the equation.
What is a chemical equation that shows the same number of each kind of atom on both sides of the equation called?
Balanced
How can use the law of conservation of mass to help you balance a chemical equation?
The law of conservation of mass means that the same number of each atom must be present on both sides of the equation, so that the mass of the reactants equals the mass of the products.
What is an imperfectly balanced equation?
An equation for a chemical reaction in which the number of atoms for each element in the reaction and the total charge are not the same for both the reactants and the products. In other words, the mass and the charge are not balanced on both sides of the reaction. This is also called as a unbalanced equation.
How do you preserve the law of the conservation of mass in a chemical equation?
By making sure that the same numbers of each type of atom appear on both sides of the balanced equation for the reaction.
Is the products of the reaction shown in a balanced chemical equation?
. A balanced equation is an equation for a chemical reaction in which the number of atoms for each element in the reaction and the total charge is the same for both the reactants and the products. In other words, the mass and the charge are balanced on both sides of the reaction.
