2Mg + 0 2 = 2MgO
WORD EQUATION: Magnesium + Oxygen --> Magnesium oxide SYMBOLS: 2Mg + O2 --> 2MgO
A balanced equation MUST have EQUAL numbers of EACH type of atom on BOTH sides of the arrow.The balanced equation for the reaction magnesium chloride plus sulfuric acid is;MgCl2 + H2SO4 ------> MgSO4 + 2HCl.
MgBr2 + Cl2 --> MgCl2 + Br2
MgCl2 + H2SO4 ---> MgSO4 + 2HCl
NaO2-NaO+O
You would start with writing the equation out, ensuring the compounds are balanced and neutral: MgO + H2O -----> Mg(OH)2 In this case, the equation is already balanced - there are two hydrogen, one magnesium, and two oxygen atoms on each side.
