What is the coefficient for water in the balanced equation C5H12 o2-Co2 H20?
6
What is h2 plus o2 plus equals h20?
The chemical reaction between hydrogen and oxygen produces water.
Is the equation C3H6 plus O2 yields CO2 plus H20 balanced?
No, the balanced equation is 6Ca + 3O2 ---> 6CaO. The product, calcium oxide, is CaO and not CaO2.
What is the balanced equation for HgO?
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.
How can I tell if a chemical reaction is balanced or not balanced?
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.
What is the coefficient for H20 when the following equation is balanced K plus H20 plus KOH plus H2?
2K + 2H2O --> 2KOH + H2 The balanced equation shows that there is a 2 in front of water.
What is h20 h2 o2 balanced?
2h2o -> 2h2 + o2
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 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.
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 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 coefficient for water in the balanced equation C5H12 o2-Co2 H20?
6
Which set of coefficients balance the following chemical equation H2 02 H20?
2H2 + O2 --> 2H2O
H2 plus O2 equals H2O If you have 1.42 moles of hydrogen how many moles of oxygen will react with it?
Balanced equation first. 2H2 + O2 >> 2H2O 1.42 mol H2 ( 1mol O2/2mol H2 ) = 0.71mol O2 to react with H2
Write a balanced equation for the ignition reaction of hydrogen in air?
2 H2 + O2 = 2 H2O
What is the balanced equation for the reaction between 02 and H2?
2h2 + o2 -> 2h2o All letters capitalized!!
What is the balance equation for zinc metal plus oxygen gas?
Zn+ H2O ---> ZnO + H2 Zn+ H2O ---> ZnO + H2
