Make the following conversion. 50.5 cm = hm 0.0505 0.00505 50,5000 5,050

we know that hm = hectomer =

1 hm = 100 m

as 1m = 100 cm

or 1hm = 10000 cm

50.5 cm = 50.5 X 10^-4 hm = 0.00505 hm

one negative thing it that it can kill water animals. another negative thing is it can cause the destruction of ecosystem. one way water pollution can be reduced is to conserve energy.

c. electrical charges of ionic bonds.
