The most distant planet is pluto
Answer:
D
Explanation:
Solid, Liquid and Gas are the states of matter. Light is neither a solid, a liquid, nor a gas.
The H3O in a solution is 12.57.
<u>Explanation</u>:
The hydronium ion concentration can be found from the pH by the reverse of the mathematical operation employed to find the pH.
pOH = -log[H3O]
pOH = -log(3.75x10^-2)
= 1.43
Now, pH = 14 - 1.43
= 12.57
The H3O in a solution is 12.57.
X has valency 3 and oxide ion has valency 2
So, the formula of oxide will be X
2
O
3
