How do you balance 2H2 O2 2H2O O2?
2H2O2 ==> 2H2O + O2 the equation is balanced
What type of reaction is 2H2O 2H2 plus O2?
2H2O--->2H2 + O2 is a redox reaction because electrons are exchanged during electrolysis.
What is h20 h2 o2 balanced?
2h2o -> 2h2 + o2
In the chemical equation 2H2 O2 ---?
H2O2: Peroxide. 2H2 + O2 -> 2H2O aka water. Use subscript next time (5 button from the left)
What type of reaction is hydrogen plus oxygen equals water?
I'm not so sure, but: 12H2 + 2N3O6 = 12H2O + 3N2
2h2o 2h2 plus o2?
Water can be broken down to oxygen and hydrogen and hydrogen can be ignited in oxygen to form water. 2H2O --> 2H2 + O2 (takes energy) 2H2 + O2 --> 2H2O (releases energy)
How do you balance 2H2 O2 2H2O O2?
2H2O2 ==> 2H2O + O2 the equation is balanced
What type of reaction is 2H2O 2H2 plus O2?
2H2O--->2H2 + O2 is a redox reaction because electrons are exchanged during electrolysis.
What is h20 h2 o2 balanced?
2h2o -> 2h2 + o2
How many moles of h2o are produced when 2.55 moles of O2 react?
4
Equation for the combustion of hydrogen?
2h2 + o2 ----> 2h2o
In the chemical equation 2H2 O2 ---?
H2O2: Peroxide. 2H2 + O2 -> 2H2O aka water. Use subscript next time (5 button from the left)
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
Balance the equation1.H2+ O2=H2O?
= H2+O2 =2H2+O2=2H2O
What type of reaction is hydrogen plus oxygen equals water?
I'm not so sure, but: 12H2 + 2N3O6 = 12H2O + 3N2
What is the relationship between the equations for the decomposition of water and the reaction of hydrogen and oxygen to form water?
They are reversible reactions. 2H2 + O2 ----> 2H2O (formation of water) 2H2O ----> 2H2 + O2 (decomposition of water)
The balanced equation for the decomposition of hydrogen peroxide?
One molecule of Oxygen Gas (O2) combines with two molecules of Hydrogen Gas (2H2) to form two molecules of water 2H2O. O2+2H2=> 2H2O There are the same numbers of H's and O's either side of the = meaning the equation is balanced, in respect of the fact that Oxygen and Hydrogen Gas have diatomic molecules (2 atoms stick together)
