Explanation:Please see attachment for explanation
Answer:
When for example, heating up an ice cube the particles of the ice start to vibrate fast enough to get separated into liquid caused from high temperature. So the answer is Higher.
Answer:
Na(OH)²
Explanation:
We look for the charges in the periodic table
<span> A homogeneous mixture is composed of a single visible phase while a heterogeneous mixture has two or more</span>
By using the ICE table :
initial 0.2 M 0 0
change -X + X +X
Equ (0.2 -X) X X
when Ka = (X) (X) / (0.2-X)
so by substitution:
4.9x10^-10 = X^2 / (0.2-X) by solving this equation for X
∴X ≈ 10^-6
∴[HCN] = 10^-6
and PH = -㏒[H+]
= -㏒ 10^-6
= 6
