form the molar concentration of the Ca(OH)2 which is a base we can deduct the pOH
pOH=-lg[OH-]
[OH-]=8.8 x 10-4 M
pOH=4
pH=14-pOH
pH=10
-lg[H+]=10
[H+]=10^-10
Answer:
The solution with [OH-] = 3.2x10-3 M will have an [H+] of 3.09x10–12 M.Explanation:
your answer would be C hope this helps
Answer:
197.5pm
Explanation:
Given parameters:
Diameter of the atom = 395pm
Unknown:
Radius of the atom =?
Solution:
Radius is the half of diameter;
Radius = 
Radius = 
= 197.5pm
B. A mixture of flour, sugar, eggs, and butter is baked to become a cake. Remember chemical change is when a substance combines with another to form a new substance. The answer wouldn't be A because the flour and sugar are mixing together, but they could be separated to their original forms. It wouldn't be C because the egg is only broken not chemically changed or formed with anything else. It wouldn't be D because the chocolate squares could be frozen or hardened to change it from icing. B is the best answer. Hope this helps!
