The same number you started with. In every chemical reaction the total number of atoms at the start is the same as the number of atoms at the end.
being able to write a balanced equation for a reaction is very important. By balancing an equation we can tell how much material we will need to start with, what the likely products to form, and how much of these products will form
APEX:)))) --Add all the elements togetherSubtract the total amount of elements from the products
The chemical equation is 'NaCl'. However, in chemistry, a 'salt' is any metal cation and any acid radical anion. So something like CaCO3 ( Calcium carbonate) is a salt. In every day terms 'salt' is the white crystalline powder used in food preparation. which is NaCl . 'Na' is the sodium cation (Na^+) and the chloride 'Cl' is the acid radical anion (Cl^-) .
In an equation the reactants are the on the left of the arrow, and the products are on the right. For example if you had the following equation: 2H2 + O2 => 2H2O 2H and O will be the reactants and H2O is the product.
yes and they are able to be balanced.

One side is equal to the other.
It is important to balance the equation, so that you know the exact ratio of reactants required and products formed. If you don't consult a balanced equation, some of your reactant may not completely consume in reaction or sufficient product is not formed during experiments.
It should have equal no. of atoms of different elements in the reactants and products. It should have equal masses of various elements in reactants and products.
If you count all of the atoms of each element on the left and all the atoms of each element on the right and the numbers on the left and right are equal for EVERY element, then the equation is balanced.
On either side, there are the same amount of atoms of each type. You can't have O2 +H2 > H2O, for example, because you would have lost an atom of oxygen in the reaction, which defies the Law of Conservation of Mass.
Balanced. The mass of the reactants must be equal to the mass of the products (the law of conservation of mass)
A chemical equation is a way of showing on paper what is happening in the laboratory or the world as chemicals interact. Here are some sentences.Our teacher made us write down the chemical equations we were going to study every day before we started class.I can't really understand this chemical equation.The chemical equation says that these chemicals should combine together.
There cannot be a balanced chemical formula for just a compound of something. You need a reactant to produce a product in order to balance an equation. In this case, you can get a chemical formula by this chemical name: calcium hydrogen carbonate. Since calcium has a +2 charge and hydrogen carbonate has a -1 charge, you need two hydrogen carbonates for every one calcium ion. The chemical formula is: Ca(HCO3)2.
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.
