Hello

how are you

i hope you are doing well

can you please help me with these questions

please do not forget the significant figures

thank you

1 .Predict whether the entropy change for each of the following reactions will have a positive value or anegative value . Calculations are not necessary !*( 2 ) CHA ( 8) + H2 ( 8) - C2Ho ( 8 )|( b ) 2 SO ; ( 8) - 2 50 2 ( 8) + 02 ( 8 )|( C ) 4 HCI ( 8 ) + SiO z ( S , quartz ) _ Sick ( 8 ) + 2 H 20 ( 8 )2 .Calculate the entropy change at 25 0 C for the following reaction :"0 . 25 P x ( s , white ) + 1.5 (12 ( 8 ) - PCl; ( 8 ) .\The entropy contents of the reactants and product at 25 Care as follows :"SubstanceS, J / mol .
