Answer 1

1) Mg(OH)2 ==(термический нагрев )=== MgO + H2O
2) MgCO3 ===(термический нагрев )=== MgO + CO2
3) MgSiO3 ===(термический нагрев )=== MgO + SiO2

Answer 2

Equations for the Decomposition Reactions Forming Magnesium Oxide

To form magnesium oxide, we can consider the decomposition of magnesium-containing compounds. Here are three possible equations for the decomposition reactions:

1. Decomposition of Magnesium Hydroxide: - Equation: `Mg(OH)2 -> MgO + H2O` - Explanation: Magnesium hydroxide decomposes to form magnesium oxide and water. - Source: 2. Decomposition of Magnesium Carbonate: - Equation: `MgCO3 -> MgO + CO2` - Explanation: Magnesium carbonate decomposes to produce magnesium oxide and carbon dioxide. - Source: 3. Decomposition of Magnesium Nitrate: - Equation: `2Mg(NO3)2 -> 2MgO + 4NO2 + O2` - Explanation: Magnesium nitrate decomposes to yield magnesium oxide, nitrogen dioxide, and oxygen. - Source: These equations represent the decomposition reactions that result in the formation of magnesium oxide.
