The right answer for the question that is being asked and shown above is that: "A. 940.8 N." Helen is standing in the hallway with her friend Janet, next to Helen's locker. Each girl has a body mass of 48 kilograms (kg), and thus each exerts a <span>force of 470.4 Newtons (N) on the hall floor.</span>
Answer:
32 ° F
Explanation:
Freezing temp for water is 32 degrees at 1 atm
Oxygen has 6 valence electrons, so B
The elephant has more inertia than the dog so it takes more force to change the motion of the elephant.
Answer: 5.48
Explanation:
pH is the negative logarithm of hydrogen ion concentration in a solution.
Mathematically, pH = - log(H+)
where H+ represent the concentration of hydrogen ion
So, to get the pH of the solution with [H +] = 3.25×10-6 M:
Apply, pH = -log(H+)
pH = - log (3.25×10-6 M)
pH = - ( -5.48)
(Note that the minus signs will cancel out each other)
Therefore pH = 5.48
Now we know that the pH of the solution with hydrogen ion concentration of 3.25×10-6 M is 5.48 (i.e slightly acidic)
Thus, we can finally say 5.48 is the pH of the solution within a solution with pH = 4.50
