If you measured the ph of stomach acid and of bleach,
a. both would be above 7.
b. the ph of stomach acid would be below 7, but the ph of bleach would be above 7.
c. the ph of stomach acid would be above 7, but the ph of bleach would be below 7.
d. both would be below 7.

a: 45.9 meters

b: 4.29 seconds

step-by-step explanation:

a: h(t)=1/2(-9.8)(3)^2+0(3)+90

h(t)=-4.9(3)^2+90

h(t)=-44.1+90

h(t)=45.9 meters

b: 0=1/2(-9.8)(t^2)+0t+90

0=-4.9t^2+90

-90=-4.9t^2

18.37=t^2

t=4.29 seconds

in the second question, the numbers aren't exact, but they're a close approximation.

there are no statements provided but here is why:

sulfur belongs to group 16 because it can be found in nature whether it is in a free or combined state.
