If you are told that a material is a base ,what does that tell about the ph of the material?

The pH is larger than 7.

The relationship between pH and pOH is

pH + pOH = 14

If something is a base, it's pH is greater than 7.

It's pOH is between 0 and 7.

explanation:

v=uf/(u-f)

= 5.10/(5-10) convex lens has positive focal length

=50/-5

=-10 cm (formed at other side)

f=ma a/f/m a= 480/60 a = 8m/s/s that is quick wow
