i need help for the three questions

Predict whether S for each reaction would be greater than zero, less than zero, or too close to zero to decide. H2(g)+Cl2(g)2HCl(g) 2HBr(g)+Cl2(g)2HCl(g)+Br2(g) S0. Choose all that apply. S(s,rhombic)+2CO(g)SO2(g)+2C(s,graphite)2C2H6(g)+7O2(g)4CO2(g)+6H2O(g)CH4(g)+H2O(g)CO(g)+3H2(g)2H2(g)+O2(g)2H2O(g)NH4HS(s)NH3(g)+H2S(g) Which of the following transformations represent an increase in the entropy of the system.
