not given the experimental drug but are otherwise treated the same as the experimental subjects.
hypothesis
experiment
theory
All of the above
Explanation / Answer
1) (e) Not given the experimental drug but are otherwise treated the same as the experimental subjects.
2) (a) observation
3) (a) data
4) (c) The elements in each period have similar chemical properties.
5) (b) Add up the number of protons and neutrons in the atom.
6) (a) 19
7) (c) Protons and neutrons
8) (b) Four
11) A buffer helps maintain the pH of a solution.
12) (3)
[H3O+] = 10-pH or [H3O+] = antilog (- pH)
pH of 3
3 = - log [H3O+]
-3 = log [H3O+]
[H3O+] = 10-3 = 1 x 10-3 M
