Metal with air (oxygen) – combustion
reaction
–Magnesium + oxygen ® magnesium oxide
–Mg (s) + O2 (g) ® MgO (s)
–Zinc + oxygen ® zinc oxide
–Zn (s) + O2 (g) ® ZnO (s)
–Sodium + oxygen ® sodium oxide
–Na (s) + O2 (g) ® Na2O (s)
–Aluminum + oxygen ® aluminum oxide
–Al (s) + O2 (g) ® Al2O3 (s)
In general then,
–Metal (s) + oxygen (g) ® metal oxide (s)
