Guise I need help on this homework question please, it's really bothering me and I am stuck.

8.0 mole of O2(g) is mixed with 10.0 moles of SO2(g) in a 2.0L container forming SO3(g). If 3.0 moles/L of SO3(g) remains at equilibrium. 1.0 mol/L of SO2(g) is removed from the equilibrium, calculate the new eq'm [ ]'s.So I make the rice table 3O2(g) + SO2(g) <--> 2SO3(g) r 3 ...

Yes, so if Ch20(s) = 2.05 J/g.*c and Ch20(g) = 2.08 J/g.*c and we need to find Qsurroundings of each of the 5 parts, what would I do?

We have a tricky question for homework that is starting our new unit of phase changes, after we have been doing calorimetry 120.0g of an unknown solid at 235*c is added to a 1.5kg piece of ice at -20*c inside a styrofoam container. After a period of time, both substances areat 120*c. What is...

How could I prove that the tangents before the maximum are positive and that the tangents after the maximum are negative? (The difference quotient was taught to me that way by my teacher, but after reading the textbook you're right, but it doesn't make a difference because it would still be...

I'm having a hard time with these two questions for an assignment in grade 12 advanced functions.. 1) Find the maximum and minimum values for each exponential growth or decay equation on the given interval. i) y=100(0.85)t, for 0 (less than or equal to) t (less than or equal to) 5 ii) y =...
