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.
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)

H2o 2h2 + o2 = 2h2o
Type your answC.2H2O (l) → 2H2 (g) + O2 (g)er here...
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
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)
2h2 + o2 -> 2h2o All letters capitalized!!
2H2O--->2H2 + O2 is a redox reaction because electrons are exchanged during electrolysis.
2h2 + o2 ----> 2h2o
2H2O2 ==> 2H2O + O2 the equation is balanced
No, chemical reactions can be reversed. For example: 2H2O -> 2H2 + O2 can change back, 2H2 + O2 -> 2H2O
= H2+O2 =2H2+O2=2H2O
2 oxygen,4 hydrogen, 4 hydrogen, and 2 oxygen so overall 12
O2(g)+2H2(g) -> 2H2O(g) (Remmeber heat/energy must also go into the reaction.) 2H2 + O2 ---> 2H2O
They are reversible reactions. 2H2 + O2 ----> 2H2O (formation of water) 2H2O ----> 2H2 + O2 (decomposition of water)
2H2 + O2 --> 2H2O
Water 2H2+O2 --> 2H2O
