What is h20 h2 o2 balanced?

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.


Is H2O-H2 plus O2 a balanced chemical equation?

No. It would have to be H2O2 - H2 = O2 in order to be balanced.


What is the coefficient for H20 when the following equation is balanced K plus H20 plus KOH plus H2?

2K(s) + 2H2O(l) = 2KOH(aq) + H2(g) The eq'n is balanced. The coefficients ( molar ratios) in order of the reation eq'n are 2:2:::2:1


What is the mistake in H2 plus O2 equals H20?

It is not balanced. There should be a 2 in front of H2 and H2O


What is the balanced equation for the reaction between 02 and H2?

2h2 + o2 -> 2h2o All letters capitalized!!


Which set of coefficients balance the following chemical equation H2 02 H20?

The balanced chemical equation is 2H2 + O2 → 2H2O. This means that the coefficients are 2, 1, and 2, respectively.


What is the water equation?

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

What is the balanced symbol equation of water?

The balanced symbol equation for water is 2H2 + O2 -> 2H2O.


What is the balance of K Br2 2KBr?

You need to have values for K, Br2 and 2KBr in order to find out the balance. For example, if you had the values as H2 + O2 = H20 the balanced chemical equation would be 10 H2 = H20.


Is H2O2--H2O plus O2 a balanced equation?

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.
