Answer: State
Explanation:
The rock on the left is more shiny than the right, so that’s incorrect.
The rocks are not the same color, so that’s also incorrect.
Even though you can’t feel the textures, the right rock looks grainy and the left on doesn’t.
They both are solid, so that is the correct answer.
<span>100,000 times more. The rule is that the product of the concentration of (H+) and (OH-) in molars is always 10^-14 (if it is more, they combine and produce simple water which brings the product back down to this number again. If it is less, water molecules will split to bring the product back up to equilibrium).
pH 9 means (H+) is 10^-9 molar. But that means (OH-) is 10^-5 at the same time.
pH 4 means (H+) is 10^-4 molar. But that means (OH-) is 10^-10 at the same time.
10^-5 / 10^-10 = 10^5 or 100,000 times more.</span>
