That is a balanced oxidation-reduction reaction. Hydrogen is oxidized, while chlorine is reduced.
2F2 + 4NaOH >> 4NaF + O2 + 2H2O
The chemical equation h2 + o2 -> h2o represents the reaction between hydrogen gas and oxygen gas to produce water. This reaction is a combustion reaction where hydrogen and oxygen combine to form water in a highly exothermic reaction, releasing energy in the form of heat and light.
I assume you were looking to balance the reaction: CH4 + 2O2 --> CO2 +2H2O
No. First Na is not a diatomic element so Na2 is not correct. Oxygen is a diatomic element so if it is by itself, there has to be a sibscript of 2. A balanced equation would be 2 Na plus O2---- 2(NaO) plus you cannot have a number in the middle of the product.
When mixed, sulphuric acid (H2SO4) and sodium hydroxide (NaOH) will undergo a neutralization reaction to form water (H2O) and sodium sulfate (Na2SO4). The balanced chemical equation for this reaction is 2NaOH + H2SO4 → 2H2O + Na2SO4.
It is an eothermic type of reaction.
A balanced chemical reaction.
This is an oxidation-reduction reaction.
A combustion reaction.
The chemical reaction is: CH4 + 2O2 --> 2H2O + CO2 CO2 is the carbon dioxide.
The products of this chemical reaction are carbon dioxide (CO2), water (H2O), and energy.
2H2 + O2 --> 2H2O
2F2 + 4NaOH >> 4NaF + O2 + 2H2O
It's a chemical reaction.
The reaction between hydrogen and oxygen to form water is a synthesis reaction. It is also a combustion reaction since it involves a chemical reaction of a fuel (hydrogen) with an oxidant (oxygen) to produce water and release energy in the form of heat.
An exothermic chemical reaction.
The balanced chemical equation for the reaction is: 3Si2H3 + 8O2 --> 2SiO2 + 6H2O
