Answer:

"The distance the spring stretches " is the correct option.

Explanation:

The Hooke's law for a spring is given by :

F_{spring}=-k\Delta x

Where

k is spring constant in N/m

\Delta x is the compression or stretching in the spring

Hence, the correct option for \Delta x is (b) "the distance the spring stretches .

For hydrocyanic acid, HCN, Ka = 4.9 × 10-10. Calculate the pH of 0.20 M NaCN. What is the concentration of HCN in the solution?
gogolik [260]
By using the ICE table :

initial    0.2 M            0           0
change -X                 + X           +X
Equ     (0.2 -X)            X               X

when Ka = (X) (X) / (0.2-X)
so by substitution:

4.9x10^-10 = X^2 / (0.2-X) by solving this equation for X 
∴X ≈ 10^-6
∴[HCN] = 10^-6

and PH = -㏒[H+]
             = -㏒ 10^-6
             = 6
