Factor 2h−2
2h−2
=2(h−1)
Answer:
2(h−1)
decomposition reaction
exothermic
2H2 + O2 --> 2H2O
The balanced chemical equation for the reaction C2H2 + H2 → C2H6 is: C2H2 + 2H2 → C2H6
A balanced chemical reaction.
(2h-3)(h+1) = 0 h = 3/2 or h = -1
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)
it goes to the other formed water molecule, there are 2 oxygen atoms in 2 molecules of water
2H2
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.
The balanced equation for the reaction of C + 2H2 → CH4 is: C + 2H2 → CH4. This equation is already balanced. Each side has 1 carbon atom and 4 hydrogen atoms.
Hydrogen is naturally H2 so when you combine two H2 molecules, you will get 2H2. It won't be H4 as it will only exist in pairs, not fours. If you are combining H + H, you will get H2 So either: H+H → H2 Or H2 + H2 → 2H2
