How does balancing an equation support the law of conservation of matter?

Answer 1

You wouldn't use a chemical equation to support conservation of matter rather, the Law of Conservation of Matter is what reqires us to balance equations. Conservation of matter says that matter can't be created or destroyed by physical or chemical processes, including chemical reactions. Therefore we must end up with the same amount of matter that you started with. This is why we write, and balnce, chemical equations. Example H2O-------> H2 + O2 is not balanced because one side has 2 Oxygens and the other has 1. 2H2O---------> 2H2 +02 is balanced

Answer 2

The Law of Conservation states matter cannot be created or destroyed, the poducts formed must consist of the atoms which form the reactants. This simply means that chemical equations must be "balanced" so that there is any equal amount of atoms on either side of the equation (equal number of moles of atoms).

For example:

3H2 + N2 --> 2NH3

There are 2 moles of N, and 6 moles of H on either side, so none was created or destroyed. (moles are a measure of the number of molecules, just like a dozen is 12, a mole is 6.022 x 1023)

Note that the above equation is actually an equilibrium equation.

Answer 3

the law of concervation of matter states that matter cannot be created nore destroid. this applys to a chemical equation because after a reaction (say an explotion) matter needs to be accounted for. u should have the same amout in the end as what u start with. weather its matter or energy. i think of it as a mathematican equation. a number cannot just dissapear. 4-2=2. its the same on both sides.

Answer 4

It shows that matter can not be created or destroyed.

For example, Na + Cl --> NaCl.

Or, Ca + 2Cl --> CaCl2.

There are an equal amount of particles of each corresponding atom on each side of both equations. This shows that matter is neither created nor destroyed, only changed.

Answer 5

According to the law of conservation of matter, matter is neither created nor destroyed.It means we must have the same number and type of atoms after the chemical change as were present before the chemical change. That means,in a chemical equation the number of atoms on the products and reactants side should be same.

Answer 6

Balancing an equation ensures that the same number of each type of atom is present on both sides of the equation. This supports the law of conservation of matter, which states that matter cannot be created or destroyed in a chemical reaction, only rearranged. Balancing the equation shows that the total mass of the reactants is equal to the total mass of the products.

Answer 7

The law of conservation of matter hasn't a chemical equation.

Answer 8

The mass of reactants is equal to mass of products.
