Select each process that produces an increase in the entropy of the system: check all that apply. check all that apply. cao(s) + co2(g) → caco3(s) hcl(g) + nh3(g) → nh4cl(s) co2(s) → co2(g) 2 so2(g) + o2(g) → 2 so3(g)

2SO2(g)+O2(g)→2 SO3(g), here reaction entropy decreases as the number of gas moles decreases from reactions to products.
HCL(g)+NH3(g)→NH4CL(s), entropy decreases as molecules of gas are converted into solid.
CO2(s)→CO2(g), entropy increases as gas is formed from a solid.
Cao(s)+CO2(g)→Caco3(s), entropy increases as gas is converted into a solid.
