Answer:
yes it is true.
Ice floats on the surface of water because ice is less dense than liquid water
Explanation:
(H+)(OH-) = Kw
kw= 1 x10^-14
OH-= 1 x10 ^-11
(H+)= KW / OH-
concentration of H+ = (1x10^-14) /.(1 x 10 ^-11) = 1 x10 ^-3
Ph= -log (H+)
PH=-log ( 1 x 10 ^-3) = 3 therefore the solution is acidic since the PH less than 7
When there is more thermal energy, there are less intermolecular forces. I hope this answers your question ☺️☺️
