Consider the chemical equations shown here. c(s) + 2h2(g) 4ch (g) c(s) + 2c12(9) - cc14(9) h2(g) + cl2(g) → 2hcl(g) what is the overall equation for the reaction that produces ccl4 and hcl from ch4 and cl2? o o ch (9)+cl2(g) → ccl4 (9) +hcl(9) ch (9)+4cl2(g) → cci (9) + 4hcl(9) ch_(g) + cl2(g) +h2(g) → cci.(g) + hcl(g)
