Note that this first question is based on week 9 materials. A 50 mL solution containing 35 mM MnCl2 , 18.0 mM cyclohexylamine, and 66.4 cyclohexylammonium, is titrated with a 40 mM solution of EDTA. Determine the amount of manganese free in solution, as pMn2+ , at the points of the titration indicated below:

What happens when light is scattered?

According to the kinetic-molecular theory, what happens to a liquid when it is transferred from one container to another? the volume and the shape stay the same. the volume increases to fill the new container, but the shape stays the same. the volume stays the same, but the shape changes to fit the new container. the volume and the shape change to fill the new container.

At a certain temperature the rate of this reaction is first order in hi with a rate constant of : 0.0632s2hig=h2g+i2g suppose a vessel contains hi at a concentration of 1.28m . calculate how long it takes for the concentration of hi to decrease to 17.0% of its initial value. you may assume no other reaction is important. round your answer to 2 significant digits.
