What is the balanced equation for Liquid water is produced when hydrogen gas and oxygen gas combine?
H2o 2h2 + o2 = 2h2o
2H2O 2H2 O2?
I think you've answered your own question. 2H2 plus 02 forms 2H20.Yes, but perhaps he doesn't know the product is the part on the right side of the arrow. In this case, as you said, 2H2O.
Which one of the following is a combination reaction?
Type your answC.2H2O (l) → 2H2 (g) + O2 (g)er here...
What releases water and energy?
Combustion of hydrogen gives a lot of heat and water. The stoichiometric reaction of hydrogen with oxygen is: 2H2(g) + O2(g) gives 2H2O(l) + 572 kJ Hydrogen's Enthalpy of Combustion is 286 kJ/mole
What type of reaction is 2H2O 2H2 plus O2?
The given reaction is a decomposition reaction where a single compound (2H2O) breaks down into two or more simpler substances (2H2 and O2).
Is 2H2 plus O2 equals 2H2O plus heat endothermic or exothermic?
exothermic
How do you balance the equation for H2 plus O2 H2O?
This simple equation is: 2H2 + O2 = 2H2O
Is 2H2 2O2 2H2O balanced?
No, the chemical equation 2H2 + 2O2 -> 2H2O is not balanced. It should be balanced as follows: 2H2 + O2 -> 2H2O.

What is the balanced chemical equation of o plus h equals h2o?
2H2 + O2 --> 2H2O
Is the formula 2h2 plus o2 balanced or unbalanced?
The formula 2H2 + O2 is unbalanced. It represents the reaction of hydrogen gas with oxygen gas to form water (H2O). To balance the equation, it should be written as 2H2 + O2 → 2H2O.
What kind of chemical relation is shown 2H2 plus O2 equals 2H2O?
A balanced chemical reaction.
What is the balanced equation for the reaction between 02 and H2?
The balanced equation for the reaction between O2 and H2 is 2H2 + O2 -> 2H2O.
How do you balance 2H2 O2 2H2O O2?
The balanced chemical equation for the reaction involving 2H2 + O2 -> 2H2O + O2 is already balanced as written because the number of atoms of each element is the same on both sides.
Equation for the combustion of hydrogen?
2h2 + o2 ----> 2h2o
Is it correct to say that chemical changes are not reverisble but phycial changes are?
No, chemical reactions can be reversed. For example: 2H2O -> 2H2 + O2 can change back, 2H2 + O2 -> 2H2O
