Question- Without doing any calculations, determine the sign of ?S(sys) for each of the following chemical reactions:

1) Mg(s)+Cl2(g) --> MgCl2(s)

a) ?S > 0

b) ?S < 0

2) CH4(g)+2O2(g) --> CO2(g)+2H2O(l)

a) ?S > 0

b) ?S < 0

3) 2H3O(aq) + CO3 2-(aq) --> CO2(g) +3H2O(l)

a) ?S > 0

b) ?S < 0

4) SO3(g) + H2O(l) --> H2SO4(l)

I am thankful to receive an expert help to solve the above problem
