How do you balance 2H2 O2 2H2O O2?
2H2O2 ==> 2H2O + O2 the equation is balanced
Is 2H2 2O2 2H2O balanced?
NO!!! 2H2 means that there are four ( 2 x 2) hydrogen atoms , in two molecules each of two atoms. Similarly 2O2 means that there are four ( 2 x 2) oxygen atoms , in two molecules each of two atoms. However, 2H2O means H2O + H2O . Each H2O is H-O-H plus H-O-H This means that there are 4 hydrogen atoms , but only 2 oxygen atoms. So a reaction is 2H2 + 2O2 = 2H2O + O2 ( 2 oxygen atoms (O=O) remain unused). More correctly this would be written as 2H2(g) + O2(g) = 2H2O(l)
What type of reaction is 2H2O 2H2 plus O2?
2H2O--->2H2 + O2 is a redox reaction because electrons are exchanged during electrolysis.
What is the Balanced equation for the combustion reaction of pure oxygen and pure hydrogen to produce water?
O2(g)+2H2(g) -> 2H2O(g) (Remmeber heat/energy must also go into the reaction.) 2H2 + O2 ---> 2H2O
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.
How do you balance 2H2 O2 2H2O O2?
2H2O2 ==> 2H2O + O2 the equation is balanced
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)

Is 2H2 O2---2H20 balanced?
2H2 + O2 ---> 2H20 is balanced when total numbers of atoms of EACH element seperately are equal on both sides ('Reactant' and 'Product' side): Left (2x H2=) 4 H atoms and (1x2 O=) 2 O atoms Right (2x H2=) 4 H's and (2x1 O=) 2 O's
How many moles of h2o are produced when 2.55 moles of O2 react?
4
What is the balanced equation for the reaction between 02 and H2?
2h2 + o2 -> 2h2o All letters capitalized!!
What type of reaction is 2H2O 2H2 plus O2?
2H2O--->2H2 + O2 is a redox reaction because electrons are exchanged during electrolysis.
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
Equation for the combustion of hydrogen?
2h2 + o2 ----> 2h2o
Balance the equation1.H2+ O2=H2O?
= H2+O2 =2H2+O2=2H2O
What is the Balanced equation for the combustion reaction of pure oxygen and pure hydrogen to produce water?
O2(g)+2H2(g) -> 2H2O(g) (Remmeber heat/energy must also go into the reaction.) 2H2 + O2 ---> 2H2O
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)
