Primary and secondary amines form hydrogen bonds among themselves. Assume you have a solution of ethanamine (ethylamine). Several proposed amine dimers are presented with the hydrogen bond highlighted as a dotted line. Draw 2 molecules of ethanamine and show a hydrogen bond formed between them.

What is the ph of a solution that has a hydrogen ion concentration of 1.0 * 10 -9 m?

‘which reaction would most likely require the use of an inert electrode?

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)
