For the simple decomposition reaction AB(g)  A(g) + B(g) rate = k [AB]2 and k = 0.2 L/(mols). How long will it take for [AB] to reach 1/3 of its initial concentration of 1.50 M?

Why are the trends and exceptions to the trends in ionization energy observed?

There is a single path for electrons. the current decreases when additional resistors are added. the current will be the same in each resistor. these statements best describe a(n) circuit.

Aradio signal from a gps satellite take only about 0.067 seconds to reach a gps reciever. if the speed of light is about 300,000km/s, then approximately how far away is the reciever from from the satellite?
