Mg stands for magnesium and O stands for oxygen, on the chemical reaction of both the following happens in the presence of heat:
Mg + O ---> MgO
magnesium + oxygen = magnesium oxide
Mg equals Mg2+ plus 2e-
The balanced symbol equation for carbon plus oxygen yielding carbon dioxide is: C + O2 -> CO2
There are two atoms of oxygen on each side.
The reaction is between Mg and O2. 2Mg+O2->2MgO
The symbol equation for the reaction of magnesium with oxygen to form magnesium oxide is: 2Mg + O2 -> 2MgO
The balanced equation for Mg + O2 is 2Mg + O2 → 2MgO.
MgO2
C+O2 →CO2
Balanced Equation: 2Mg(NO3)2 = 2MgO + 4NO2 + O2
Mg equals Mg2+ plus 2e-
2,1,2
2Ca + 3O2 + 2C -> 2CaCO3
Mg(s) + 3/2 O2(g) + C(s) ----> MgCO3(s)
I'm not entirely sure but an unbalanced equation is: Mg + O2 -----> MgO
To balance the equation C + O2 → CO, you need to add a coefficient of 2 in front of CO. This balances the equation so that you have the same number of carbon and oxygen atoms on both sides: C + O2 → 2CO.
The balanced symbol equation for carbon plus oxygen yielding carbon dioxide is: C + O2 -> CO2
The balanced chemical equation for the reaction between Mg and O2 is 2Mg + O2 -> 2MgO. This equation shows that 1 mole of Mg reacts with 1 mole of O2. The molar mass of O2 is 32 g/mol. Therefore, 21.0 g of Mg will react with 16.0 g of O2, which is 0.5 moles of O2.
