According to the gibbs free energy equation, g = h - ts, when could a high temperature make a reaction that was nonspontaneous at low temperature spontaneous?

When enthalpy change of the reaction is endothermic and entropy change of the reaction is positive, a high T will make reaction more spontaneous (i.e. change in G becomes negative). When T is low, magnitude of enthalpy change will be greater than magnitude of (T x entropy change) and hence change in G will be positive and reaction is non-spontaneous.

state the principle of separating two immiscible liquids by separating funnel. describe an activity with diagram to separate a mixture of water and kerosene oil. answer: immiscible layers separate out in layers depending on their densities in separating funne

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.
