The equilibrium constant for the reaction is 1.1 x 106 M. HONO(aq) + CN-(aq) ⇋ HCN(aq) + ONO-(aq) This value indicates that

The given question is incomplete. The complete question is given here :

The equilibrium constant for the reaction is M.

This value indicates that

A. is a stronger base than

B. HCN is a stronger acid than HONO

C. The conjugate base of HONO is

D. The conjugate acid of CN- is HCN

A. is a stronger base than

Explanation:

Equilibrium constant is the ratio of product of the concentration of products to the product of concentration of reactants.

When ; the reaction is product favoured.

When ; the reaction is reactant favored.

; the reaction is in equilibrium.

As, , the reaction will be product favoured and as it is a acid base reaction where acts as acid by donating ions and acts as base by accepting

Thus is a strong acid thus will be a weak conjugate base and is a strong base which has weak conjugate acid.

Thus the high value of K indicates that is a stronger base than

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.
