Oxides — practice question

When silicon(IV) oxide is reacted with chlorine and carbon, liquid silicon(IV) chloride, $\text{SiCl}_4$, and carbon dioxide gas are produced. At r.t.p., which symbol equation represents this reaction?

  • A$\text{SiO}_2(\ell) + 2\text{Cl}_2(g) + \text{C}(s) \rightarrow \text{SiCl}_4(\ell) + \text{CO}_2(g)$
  • B$\text{SiO}_2(\ell) + 2\text{Cl}_2(g) + \text{C}(g) \rightarrow \text{SiCl}_4(\ell) + \text{CO}_2(g)$
  • C$\text{SiO}_2(s) + 2\text{Cl}_2(g) + \text{C}(s) \rightarrow \text{SiCl}_4(g) + \text{CO}_2(g)$
  • D$\text{SiO}_2(s) + 2\text{Cl}_2(g) + \text{C}(s) \rightarrow \text{SiCl}_4(\ell) + \text{CO}_2(g)$
