Co + 2h2 -> ch3oh
The chemical equation is:2 NaHCO3---------------------Na2O + 2 CO2 + H2O
H2,g + I2,s --> 2HIg
coefficients
The product is water:2 H2 + O2 = 2 H2O
The chemical symbol (not equation) of hydrogen is H; the diatomic molecule is H2.
No equation, it is not a chemical reaction.
The chemical formula of nitric acid is HNO3.
The chemical equation is:H2S + O2 = SO2 + H2O
The chemical equation is:2 NaHCO3---------------------Na2O + 2 CO2 + H2O
This equation is Mg + 2 HCl -> MgCl2 + H2.
A balanced chemical equation is when both the products and the reactants are balanced, or have the same number of atoms on each side of the equation. For example: 2H20 --> 2H2 + O2 This means there are 2 water molecules as the reactants (before reaction) and 4 hydrogen and 2 oxygen atoms as the products (after reaction). Technically the equation wouldn't work in real life if it weren't correctly balanced.
H2,g + I2,s --> 2HIg
2 oxygen, 4 hydrogen

If the equation has the same number of each type of atom on both sides of the arrow, it is balanced. If the number of atoms on each side of the arrow is not the same, the equation is not balanced. For example, in the equation H2 + O2 -->H2O, there are two hydrogen atoms and two oxygen atoms on the left, and two hydrogen atoms and one oxygen atom on the right. Therefore, the equation is not balanced. However, in the equation 2H2 + O2 -->2H2O, there are four hydrogen atoms and two oxygen atoms on the left and four hydrogen atoms and two oxygen atoms on the right, so the equation is balanced.
No, the equation is not balanced. On the left side there is no hydrogen (H), on the right side there is.No, the equation is not balanced. On the left side there is no hydrogen (H), on the right side there is.No, the equation is not balanced. On the left side there is no hydrogen (H), on the right side there is.No, the equation is not balanced. On the left side there is no hydrogen (H), on the right side there is.
2H2 + O2 ---->2H2O is balanced for the following reasons. Hydrogen and oxygen exist as H2 and O2 and not H and O. The product is water with a formula of H2O. To get balance the number of atoms of reactants and the number of atoms of products must be equal. They are in the balanced equation above. For these reasons the equation is balanced.
