The reaction between magnesium (Mg) and sulfur (S) to form magnesium sulfide (MgS) is a combination (or synthesis) reaction. In this type of reaction, two or more reactants combine to form a single product. Here, magnesium and sulfur react together to create magnesium sulfide, releasing energy in the process.
Combustion reaction
An acid plus a base will yield a salt and water in a neutralization reaction.
This reaction is called "metal-metal exchange reaction".
This is a single displacement reaction, specifically a redox reaction. In this reaction, iron displaces copper from copper sulfate to form iron sulfate and copper.
The unbalanced combustion reaction for methane (CH₄) is represented as CH₄ + O₂ → CO₂ + H₂. To balance this reaction, you would need to ensure that the number of each type of atom is the same on both sides. The balanced equation is: CH₄ + 2 O₂ → CO₂ + 2 H₂O, indicating that one molecule of methane reacts with two molecules of oxygen to produce one molecule of carbon dioxide and two molecules of water.

The reaction shown in the thermochemical equation is an exothermic reaction. This is because heat is a reactant (on the left side of the equation) and is released during the reaction.
This is a balanced equation and this is a Synthesis type of reaction
The general equation XY → X + Y represents a decomposition reaction. In this type of reaction, a compound (XY) breaks down into its constituent elements or simpler compounds (X and Y). Decomposition reactions often require energy input, such as heat or light, to proceed.
this is an exotermic reaction
A double replacement reaction.
Displacement reaction
This is an oxidation-reduction reaction.
This is an double-displacement reaction, in this case and acid-base reaction.
It is an eothermic type of reaction.
