MgO + 2HCl -> MgCl2 + H2O
The balanced chemical equation for the reaction is: 2 Mg + O2 → 2 MgO. This means that for every 1 mole of O2, 2 moles of MgO are produced. Therefore, if 0.200 mol of O2 reacts completely, it will produce 0.400 mol of MgO.
The oxidation half-reaction for the conversion of 2Mg to MgO is: 2Mg(s) -> 2Mg^2+(aq) + 4e^-
Oxygen (O2) is the oxidizing agent in this reaction, as it gains electrons during the reaction to form water (H2O).
When SiO2 reacts with H2O, it forms silicic acid (H4SiO4). The reaction results in the dissolution of SiO2 in water, leading to the formation of the acidic solution.
Carbon dioxide (CO2) and (H20) are the reactants that yield the product of carbonic acid (H2C03). The reaction occurs in both (equilibrium) directions by the formula H20 + CO2 <-->H2CO3.

A chemical reaction between MgO and Ca will form calcium magnesium oxide (CaMgO3) as a product. This reaction involves the exchange of ions between magnesium oxide and calcium to form a compound with both elements.
The reaction is:MgO + H2O = Mg(OH)2
When MgCO3 (magnesium carbonate) is heated, it will decompose into magnesium oxide (MgO) and carbon dioxide (CO2) gas. This reaction is a decomposition reaction, where a single compound breaks down into two or more simpler substances.
combination reaction
The decomposition reaction is:MgCO3 = MgO + CO2
The reactants are the elements or compounds that are reacting with one another. And the products are what is produced from the reaction. For example, MgO + H20 -> Mg(OH)2. MgO and H2O are the reactants. Mg(OH)2 is the product.
The balanced chemical equation is: MgO + H2O → Mg(OH)2 The product formed in this reaction is magnesium hydroxide.
A reaction doesn't occur.
This compound is the magnesium oxide, MgO.
