At a certain moment in the reaction, 2N2O5 → 4NO2 + O2 , N2O5 is decomposing at a rate of 2.5 x 10-6 mol L-1 s -1 . What is the rate of formation of O2?

How many mmols of tris-hcl are there in 100 ml of a 100 mm tris-hcl buffer solution at ph 8.1? note that the 100 mm refers to the sum of tris and tris-hcl concentrations?

Each of the following reactions is allowed to come to equilibrium and then the volume is changed as indicated. predict the effect (shift right, shift left, or no effect) of the indicated volume change. drag the appropriate items to their respective bins. co(g) + h2o(g) < => co2(g) + h2(g) (volume is decreased) pcl3(g) + cl2(g) < => pcl5(g) (volume is increased) caco3(s)< => cao(s) + co2(g) (volume is increased)

Atoms contain subatomic particles called protons and neutrons. when these protons and neutrons spilt, a lot of energy is released
