The answer as stated in the question is wrong which is why it can not be balanced. To balance
Ca + 2H20 -------> Ca(OH)2 + H2

Because H2O is the chemical formula of water and not a balanced equation.
Because the unbalanced equation shows two oxygen atoms on the left but only one on the right.

The chemical reaction between hydrogen and oxygen produces water.
No, the balanced equation is 6Ca + 3O2 ---> 6CaO. The product, calcium oxide, is CaO and not CaO2.
This equation is 2 H2O (liquid) = 2 H2 (gas) + O2 (gas)There must be 4 atoms / 2 diatomic molecules of hydrogen on each side to yield O2This is the electrolysis of water.
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.
The coefficient for H2O is 1 in the balanced equation: 2K + 2H2O + 2KOH + H2
The chemical equation given “H2 + O2 -> H2O” is not balanced. To balance it, you need to modify the coefficients in front of the molecules. The balanced equation should be: "2H2 + O2 -> 2H2O" where you have two molecules of hydrogen gas reacting with one molecule of oxygen gas to produce two molecules of water.
No. It would have to be H2O2 - H2 = O2 in order to be balanced.
It is not balanced. There should be a 2 in front of H2 and H2O
The balanced chemical equation is 2H2 + O2 → 2H2O. This means that the coefficients are 2, 1, and 2, respectively.
In order to have a balanced equation, adding the reactant H2 And O2 (H2+O2) have to come out equal on the product side and the reactant side. This would look like H2+O2 = H2O2

Zn+ H2O ---> ZnO + H2 Zn+ H2O ---> ZnO + H2
The balanced symbol equation for water is 2H2 + O2 -> 2H2O.
The balanced equation is 2K + Br2 → 2KBr. This equation shows that two moles of potassium (2K) react with one mole of bromine (Br2) to produce two moles of potassium bromide (2KBr).
No. There are two O's on the right side and three on the left. The balanced form is 2 H202 -> 2 H20 + 02. All of the O's are the letter 0 in this equation. All numbers are subscripts except the two 2's in front of the H's that have a space after them. I've taken college-level chemistry, so I remember how to do this.
The balanced chemical equation for cellular respiration is C6H12 O6+ O2--> CO2 + H20 + ATP
