Examine the following reaction: NH4Cl (s)→NH3 (g)+HCl (g)ΔH0=176 kJ

At 25 °C, this reaction has a ΔG0 of 91.1 kJ.

What is the ΔS0 of this reaction?

0.896 kJ/K

0.285 kJ/K

−0.896 kJ/K

−0.285 kJ/K

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.

explanation:

increased stability in the completion of fluorine's outer shell.

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?
