For which of the following reactions is δh∘rxn equal to δh∘f of the product(s)? you do not need to look up any values to answer this question. check all that apply. view available hint(s) check all that apply. caco3(g)→ cao+ co2(g) li(s)+12cl2(l)→licl(s) 2li(s)+cl2(g)→2licl(s) co(g)+12 o2(g)→ co2(g) c(s, graphite)+ o2(g)→ co2(g) li(s)+12cl2(g)→licl(s)

2Li(s)+Cl2(g)→2LiCl(s)

C(s,graphite)+ O2(g)→ CO2(g)

6Li(s)+12Cl2(g)→6LiCl(s)

Explanation:

Hello,

The following reactions:

2Li(s)+Cl2(g)→2LiCl(s)

C(s,graphite)+ O2(g)→ CO2(g)

6Li(s)+12Cl2(g)→6LiCl(s)

Are characterized by the presence of just elements in the reagents, thus, their enthalpy of formation is cero, so the change in the enthalpy of reaction is equal to the enthalpy of formation of the products.

Best regards.
