Counting atoms is easy. Within the formula are chemical symbols. Each symbol represents the presence of an atom of a specific element within the compound or molecule (not the same thing but different question). If more than one atom of that element is present, then a subscript behinf the symbol is used to indicate that. For instance, water is H2O. The "2" tells us that there are 2 hydrogen attoms in this compound. The presence of the "O" means that one oxygen atom is present. If we look at H2O2 (hydrogen peroxide), this tells us there is 2 hydrogen atoms AND 2 oxygen atoms because there is a subscripted 2 behind both symbols.

∙ 12y agoAll you have to do is take the subscript after the parenthesis (on the outside) and multiply it by the subscript on the inside of the parenthesis. if there are no subscripts on the inside or out just count them as one.
EX:Co(No3)2
take 2 and * it by 1 which stands for the subscript of N and it =2
take 2 and * it by 3 which stands for the subscript of O and it=6
2*1=2 (N=2)
2*3=6 (0=6)
Ex:Ca(Co3)4
4*1=4
4*3=12
C=4
O=12

What is the balanced equation of c2h60?
do you have another chemical equation with this as the answer could be 2CH30 my advice is to count the number of atoms and make sure they match if they do it is a balenced equation. If you have to write one yourself then make sure the numbers match.
What do you notice about the number of atoms on each side of a chemical equation?
That the number of atoms on the left side of the equation must be the same number of atoms that are on the right side of the equation.
What is a balanced chemical reaction?
In a balanced chemical equation there should be the same amount of atoms present in the products as there were in the reactants and only whole molecules can be formed or used (no half molecules). For example... CH4 + 2O2 = Co2 + 2H2O. If you add up the various atoms in the reactants you find 1 x Carbon, 4 x Hydrogen and 4 x Oxygen. The products contain 1 x Carbon, 4 x Hydrogen and 4 x Oxygen. The equation is therefore balanced. You will note also that 2 molecules of O2 were used as reactants in order to produce complete molecules of products.
Does a chemical equation show the number of atoms lost during a chemical reaction?
no
What chemical equation has equal numbers of reactant and product atoms?
Any chemical reaction.
What do you mean by balanced chemical equation?
A balanced chemical equation is one where the number of the same atoms on both sides are equal. A balanced chemial equation is important because during a chemical reaction, there is rearrangement of atoms only and no new atoms are added. To understand the concept of a balanced chemical equation, first consider an unbalanced chemical equation between magnesium and oxygen to form magnesium oxide. Unbalanced chemical equation: Mg(s) + O2(g) --> MgO(s) Initially, this equation is unbalanced because if we count the number of the oxygen atoms on both sides, the number are unequal. There are two oxygen atoms on the left side but only one on the right side. A balanced chemical equation is one where the number of all of the same atoms on both side are equal. We can balance chemical equations by adding numbers to the coefficient of the chemicals that are involved in the reaction. Balanced chemical equation: 2Mg(s) + O2(g) --> 2MgO(s) This equation is now balanced because if we count the number of the same atoms on both side, they are equal. There are two magnesium atoms and two oxygen atoms on both sides of the equation.

What law states that the number of atoms on the right of a chemical equation is equal to the number of atoms on the left of the chemical equation called?
This is the law of mass conservation.
What is the full balanced chemical equation?
Any chemical equation where atoms and energy are equal on each side.
What do you notice about the number of atoms on each side of a chemical equation?
That the number of atoms on the left side of the equation must be the same number of atoms that are on the right side of the equation.
Which number in a chemical equation shows you the number of atoms?
The coefficient times the subscripts in a chemical formula show you the number of atoms of each element for each substance in the equation.

no
What chemical equation shows that no atoms are lost during a chemical reaction?
This is a balanced chemical reaction.
What chemical equation has equal numbers of reactant and product atoms?
Any chemical reaction.
What do you count to decide whether or not an equation is balanced?
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.
