The types and numbers of atoms at the end of a reaction are the same as before the reaction.
True. According to the law of conservation of mass, all atoms present at the start of a chemical reaction are also present at the end, although they may be rearranged to form different compounds.
Assuming that you are referring to chemical reactions, we know that atoms are not changed by chemical reactions (except for their oxidation states). That means that all the same types of atoms are present after the reactions as were there before the reactions. The type of an atom is determined by the number of protons in its nucleus.
They will contain 18 atoms total in all the products.
Argon is an element and all the atoms in argon are argon atoms.
They will contain 18 atoms total in all the products.

If five atoms of hydrogen are reactants in a chemical reaction, typically all five atoms will be found in the products unless some sort of splitting or rearrangement of atoms occurs during the reaction. It follows the principle of conservation of mass, meaning atoms cannot be created or destroyed in a chemical reaction.
They will contain 18 atoms total in all the products.

They will contain 18 atoms total in all the products.
Argon is an element and all the atoms in argon are argon atoms.
They will contain 18 atoms total in all the products.
ion
If the reaction starts with 6 atoms of solid and 12 atoms of gas, the total number of atoms should remain the same in the products. This means there should be 6 atoms of solid and 12 atoms of gas in the products as well.
In CaSO4 (calcium sulfate), there are a total of 5 atoms present (1 calcium, 1 sulfur, and 4 oxygen). In H2O (water), there are a total of 3 atoms present (2 hydrogen and 1 oxygen). Therefore, in CaSO4 and H2O combined, there are a total of 8 atoms of all kinds present.
The sum of the masses of the atoms in an ionic compound is equal to the formula mass of the compound. It is calculated by adding the atomic masses of all the atoms present in the formula unit.
