It is synthesis since your adding them together other wise decomposition is breaking them apart
This is a decomposition reaction, which is recognizable by one reactant yielding two (or more) products.
There is no reaction that you have described. All that has been described are the reactants, which are H2O and CO2. What do they make?
combustion, because it has a hydrocarbon reactant and the products are water and carbon dioxide
Its a Synthesis reaction.
Not a combustion reaction. Combustion reactions produce CO2 and H2O.
It is a combustion reaction, which is a reaction in which a substance combines with oxygen, releasing a large amount of energy in the form of light and heat.
I assume you were looking to balance the reaction: CH4 + 2O2 --> CO2 +2H2O
No. The correct one is CO + H2O ----> HCOOH (Formic acid)
NaCl+H2O COMPELATE THE EQUATION
H2O(aq)+CO2(g)
Combustion reaction
neutralisation reaction
The combustion reaction of heptane is:C7H16 + 11 O2 = 7 CO2 + 8 H2O
Burning, oxidation.
It is an oxidation, assuming the products are CO2 and H2O
CH4 + 2O2 --> CO2 + 2(H2O), the products are CO2 and H2O
Combustion reaction.
