single replacement
The equation for the reaction is 2 H2O2 → 2 H2O + O2 Each molecule of hydrogen peroxide is split into a molecule of water and an oxygen atom. The oxygen atoms pair to form oxygen molecules. Catalase is one of the most vigorous enzymes known, and the rush of oxygen to the surface of the liquid is spectacular.
The reaction with acid to form H2 is a chemical property.
There are 2 sulfur atoms in the chemical reaction H2S plus SO2 plus H2.
This would be a synthesis reaction. General formula A + B yields AB.
synthesis reaction
2H2 + O2 -> 2H2O - reaction to produce water H2+O2-> H2O2 - reaction to produce hydrogen peroxide
It is a reaction that has only one reactant and multiple products. Meaning one chemical decomposes/splits to form others. H2O2 > H2 + O2.
single replacement
No. It would have to be H2O2 - H2 = O2 in order to be balanced.
Correctly represented, it's Mg + 2HCl --> MgCl2 + H2, and it's a single replacement reaction.
It is an eothermic type of reaction.
A single replacement reaction is shown.
Correctly represented, it's Mg + 2HCl --> MgCl2 + H2, and it's a single replacement reaction.

The most common reaction is:CO + 2 H2 = CH3OH
H2 +o2 --->h2o
