Homework Statement When a reaction mixture with a total volume of 4 L that contains 9.99 g of solid CaSO4 was stoichiometrically produced as per the balanced equation with 2.50 L of aqueous Ca2+, what molarity (M) of Ca2+ was required? Al2(SO4)3(aq) + 3 CaBr2(aq) → 2 AlBr3(aq) + 3 CaSO4(s)...

Homework Statement Will a ball, kicked at 14.0 m/s vertically and 9.0 m/s horizontally, clear a bar 3.0 m high and 20 m away from the kicker? Solve. Homework Equations Kinematics Equations. The Attempt at a Solution Haven't encountered this type of problem, didn't know where to...

Hmm, I suppose I can't. Now I've hit the bricks, I don't know how to figure it out.

What about angle 2 and 3? My answer was 55 for both of them..

Homework Statement http://i41.tinypic.com/35mno6v.jpg 2. The attempt at a solution So far, I found out that angle 4 and 5 is 55, because angle D is 110.. but I don't know if that's right. Please help!

Thanks! I got the correct answer now ;)
