Answer:
Answer D. Picture II shows a chemical change, because the same substance changes form
Explanation:
This is the temperature that water molecules slow down enough to stick to each other and form a solid crystal
A solution with hydroxide ion concentration of 4.15 x10^-6 m is basic and has a hydrogen ion concentration of 2.41 x10^-9 M
we well know thaat (H^+) (OH^-) = 1 x10^-14
by making H^+ concentration the subject of the formula
H^+ = 1 x10^-14/OH^-
H^+= 1 x10^-14/4.15 x10^-6 = 2.41 x10^-9 M
the solution is basic since OH^- ion is for basic solution
