1. The valve between a ten litre tank containing a gas at a pressure of 1 atm and a three lite tank containing a gas at 0.5 atm is opened. Compute the final pressure in the tank if nothing else is altered in the surroundings. (The two gases do not react)
2. Considering the given oxidation and reduction half-reactions,( The reaction takes place in a basic solution )balance this equationMnO-4(aq) + S2-(aq) → S(s) + MnO2(s) of the action of MnO4-( permanganate ions) on S2- (sul-fide ions.). What is the smallest possible integer coefficient of S in the combined balanced equation?
How do you calculate the force of water hitting a concrete cylindrical pole. The velocity of the water is 2 ft/s, the depth of the water is 10 ft, and diameter of the pole is 3 ft. So what would be the total force exerted on the pole by the water?
