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.
