5) After performing a routine laboratory synthesis, a chemist was left with more waste product than desired. She wanted to check the pH of the substance to properly dispose
of the waste, but her pH meter was broken, and the lab had run out of litmus paper.
However, she knew that based on her calculations, the solution likely had a hydrogen
ion, H, concentration of 8.7 x 10-5 M. What is the pH of this solution ? Choose the range
of pH values that contains the correct pH.
A) 1-3.9
B) 4-7.9
C) 8-11.9
D) 12-14

a is the answer to this question

explanation:

for step 7 table c on the lab "newtons law of action"   the average time it took the car to travel .25 meters   was 1.92 seconds.

the average time it took the car to travel 0.50 meters was 2.61 seconds

hope this : )

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
