Solid silicon (Si) and solid magnesium chloride (MgCl2) form when silicon tetrachloride (SiCl4) gas reacts with magnesium metal (Mg). Write a word equation and an unbalanced formula equation including physical states.

Silicon tetrachloride gas reacts with solid magnesium metal producing solid silicon and solid magnesium chloride.

SiCl₄ (g) + Mg (s) → Si (s) + MgCl₂ (s)

Explanation:

The reaction of SiCl₄ (g) with Mg (s) produce Si (s) and MgCl₂ (s). A way to write a word equation could be:

Silicon tetrachloride gas reacts with solid magnesium metal producing solid silicon and solid magnesium chloride.

The unbalanced formula equation including physical states is:

SiCl₄ (g) + Mg (s) → Si (s) + MgCl₂ (s)
