Answer:
The net ionic equation:
Explanation:
The given chemical reaction is as follows.
The total ionic equation is as follows.
Similar ions on the both sides of the reaction will be cancelled.
The remaining reaction is
Therefore, the net ionic reaction is as follows.
You can predict its acidity (pH).
The formula for pH is: pH = log { 1 / [H+] } = log { 1 / (1*10^-12) }
=> pH = log {10^12} = 12.
Remember that acids have pH between 1 and less than 7 and basic compounds have pH greater than 7 and less than 14.
So, you can predict that this product is a base (alkaline).
I believe the correct response would be A. The ions once dissolved in the solution are free to move
T=2T
m=10 g
m=m₀2^(-t/T)
m₀=m/{2^(-2T/T)=m/2⁻²
m₀=10/2⁻²=40 g
40 grams
