The scientist is using gel electrophoresis. Gel electrophoresis is a process used to cut DNA into fragments in order to see them.
Answer:
A(yellow) = 52
Explanation:
A(yellow) = A(total) - A(red)
= 11×6 - 7×2
= 66 - 14
= 52
Answer:
A strong acid is one which is virtually 100% ionized in solution. Other common strong acids include sulphuric acid and nitric acid.
Explanation:
Ka for weak acids is ---> Ka= (X)²/ (initial- X)
initial= 0.0400 M
to find X, you can find the H concentration using pH
[H+]= 10^-pH
[H+]= 10^-1.80= 0.016 which is X
ka = (0.016)²/ (0.0400 - 0.016) = 0.011
