Answer:
OPTION D,
AS AT THIS PLACE ONLY THIS FACTIR CAN OCCUR..
The strong electrolyte KF completely dissociates into K+ and
F- ions when it dissolves in water. When the weak electrolyte HF dissolves in
water, there are a few ions of H+ and F- present, but mostly dissolved HF
molecules. I am hoping that this answer has satisfied your query
and it will be able to help you in your endeavor, and if you would like, feel
free to ask another question.
Ionic compounds are formed by a positive ion called cation and a negative ion called anion.
I will show you some examples:
NaCl is formed by the cation Na+ and the anion Cl -
CaF2 is formed by the cation Ca 2+ and the anion F -
Li2O if formd by the cation Li + and the anion O 2-.
To tell that you use the oxidation number of each element. I did it this way
Ca F2 => Ca has oxidation number 2+ and F has oxidation number 1- then the ions have that very same charge number.
Answer:
a = 12
b = 13
Explanation:
Consider the following equivalent expressions: 38÷1312 and 38?ab What are the values of a and b? Enter the value of a followed by the value of b, separated by a comma.
The solution is attached.
