When [HClO]= 0.01 M & [ClO]^- = 0.03M & NaOH = 0.003 mol and
Ka = 3.5 x 10^-8
and the equation is:
HClO + NaOH → Na^+ + ClO^-
initial 0.01 0.003 0.03 0.03
-0.003 - 0.003 +0.003 + 0.003
Final 0.007 0 0.033 0.033
We can get the PH from this formula:
PH = Pka + ㏒[conjugent base/weak acid]
PH = -㏒Ka + ㏒[Na]/[HClO]
= - ㏒ 3.5x10^-8 + ㏒(0.033/0.007)
= 8.13
Answer:
manganese has greater ionization energy than Selenium
Answer:
Reaction rate
Explanation:
We are told that Ben observes how quickly some dry wood is burning in a campfire.
This is an example of reaction rate because it tells us the speed i.e. how fast the dry wood is reacting with the camp fire.
I know 4 is acidic so it has to be 9
