Which of the following correctly describes why the plum pudding model is no longer accepted as an accurate model of the atom?
There aren't actually negatively charged particles in atoms
o Scientists found new evidence and revised the theory to fit the data better.
o Scientists discovered that atoms actually have positively charged partides dispersed throughout a negative mass.
Scientists revised the evidence to fit this model of the atom better.

Answer:
1000 times.
Explanation:
Hello,
In this case, since the pH is defined by:
If we want to compute the concentration of hydrogen we must write:
Thus, for both the backyard soils we compute:
It means that:
It means that the concentration of hydrogen at a pH of 4 is 1000 times greater than the concentration of hydrogen at a pH of 7.
Regards.
