double decomposition
The reaction is:MgO + H2O = Mg(OH)2
A reaction doesn't occur.
When magnesium is burned, it forms magnesium oxide (MgO) as a chemical compound. This reaction occurs in the presence of oxygen, where magnesium combines with oxygen atoms to form magnesium oxide.
The reaction is between Mg and O2. 2Mg+O2->2MgO
The decomposition reaction is:MgCO3 = MgO + CO2
The reaction between MgO and H2O is a chemical reaction called a hydration reaction. In this reaction, MgO reacts with water to form magnesium hydroxide (Mg(OH)2).
chemical combination
The reaction is:MgO + H2O = Mg(OH)2
A reaction doesn't occur.
This compound is the magnesium oxide, MgO.
MgO
The reaction between MgO (magnesium oxide) and NaOH (sodium hydroxide) results in the formation of magnesium hydroxide (Mg(OH)2) and sodium oxide (Na2O). This is a double displacement reaction where the magnesium ion from MgO replaces the sodium ion in NaOH, forming Mg(OH)2 and Na2O. Magnesium hydroxide is a white solid that is sparingly soluble in water, while sodium oxide is a white solid that is highly reactive with water.
"MgO" is magnesium oxide and "H" is hydrogen, as in "Mg + H(2)O => MgO + H(2)" MgO + H2 ---> H2O + Mg
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.
When magnesium is burned, it forms magnesium oxide (MgO) as a chemical compound. This reaction occurs in the presence of oxygen, where magnesium combines with oxygen atoms to form magnesium oxide.
combination reaction
The reaction is between Mg and O2. 2Mg+O2->2MgO
