Which pair of compounds represents one Arrhenius acid and one Arrhenius base?

A)
CH3OH and NaOH

B)
CH3OH and HCl

C)
HNO3 and NaOH

D)
HNO3 and HCl

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.

let that person have a turn to speak : )

i have no clue hope you find the answer

1.43 x 10^-11 j the guy commented the awnser just making sure u see it .
