Use oxidation numbers to identify reaction is REDOX reactions. a. 2SO2(g) + O2(g) -> 2SO2(g) for 2SO2 I got: -2 for S, -2 for O for O2 I got 0 for 2SO2 I got -2 for S again, and -2 again for 0 Therefore I lost one oxygen and a REDOX reaction occured Am I right?????

A planet/moon has a mass of 77.89 × 1023 kg and a radius of 7.9 × 106 meters. What is g on the surface to the nearest hundredth of a m/s2? Once again, not really sure where to go with this. Out of the 10 problems I've only had trouble with this and one other.

How do you calculate the coefficient of friction, if it is not given to you? What would the formula be? It is a measured value. Force friction= mu*normal force. That is the usual method of solving for mu.
