Calculate the ph of a buffer solution made from 0.10 m nh3 and 0.10 m nh4cl
salt. kb = 1.8 x 10-5

b. calculate the ph of the buffer in part a, after 12 ml of 0.20 m hcl is added to 125 ml
of the buffer in part a.

c. calculate the ph when 12 ml of 0.20 m hcl added to 125 ml of water. how does
the ph compare to the ph found in part b?

Frictional forces acting on an object are often converted into energy, which causes the temperature of the object to rise slightly.

The table describes how some substances were formed substance 19 description formed by boiling pure water formed by combining three hydrogen atoms to every nitrogen atom formed by adding 5 g of sugar to 1 l of water formed by compressing carbon under high pressure based on the given descriptions, which substance is most likely a mixture?

Match the mixture with the substance// i really need on this guys (it’s a pic btw)
