Question

Magnesium oxide forms from magnesium metal and oxygen gas O2. Write a word equation and an unbalanced formula including physical states.

Answer 1

Answer:

See explanation

Explanation:

The word equation is just a statement of the reaction in words as follows;

Magnesium oxide ----> Magnesium metal + oxygen gas

An unbalanced stoichiometric equation doesn't have equal number of atoms of each element on both sides.

Hence the unbalanced stoichiometric equation is as follows;

MgO(s) -----> Mg(s) + O2(g)
