Answer:
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:
<em>Silicon tetrachloride gas reacts with solid magnesium metal producing solid silicon and solid magnesium chloride</em>.
The unbalanced formula equation including physical states is:
<em>SiCl₄(g) + Mg(s) → Si(s) + MgCl₂(s)</em>
Because they are the means by which energy needed for photosynthesis is transported into the plant in form of light ernegy
