never mind I subtracted wrong the answer is -235.4 hahaha

The values above are in the units of kJ/mol

************The values I used C(graphite): change in delta Hf=0 change in delta G= 0 change in delta S= 5.7 Cl2 change in delta Hf=0 change in delta G= 0 change in delta S= 223.1 CCl4 change in delta Hf=-139 change in delta G= -68.6 change in delta S= 214.4

I posted this question already but you never replied back :( Consider the following reaction at 298 K: C(graphite) +2Cl2 (g) -----> CCl4(l) Calculate the following quantities. Delta H: -139 kJ/mol deltaS(sys)=? J/mol*K deltaS(surr)=? J/mol*K deltaS(univ)=? J/mol*K My answer...

projectile motion
You have a boat with a motor that propels it at vboat = 4.5 m/s relative to the water. You point it directly across the river and find that when you reach the other side, you have traveled a total distance of 27 m (indicated by the dotted line in the diagram) and wound up 14 m...
