Which statement about spontaneous and nonspontaneous processes is correct? Spontaneous processes are favored by a decrease in H,

but nonspontaneous reactions are favored by an increase in H. Spontaneous processes are favored by a decrease in S, but nonspontaneous reactions are favored by an increase in S. An increase in S favors both spontaneous and nonspontaneous processes. A decrease in H favors both spontaneous and nonspontaneous processes.

Answer: Spontaneous processes are favored by a decrease in H, but nonspontaneous reactions are favored by an increase in H.

Explanation:

\Delta G=\Delta H-T\Delta S

\Delta G = gibbs free energy

\Delta H = change in enthalpy

\Delta S = change in entropy

For a reaction to be spontaneous, \Delta G= -ve. For this \Delta H  has to be negative i.e. there should be a decrease in enthalpy and \Delta S has to be positive i.e. there should be a increase in entropy.

\Delta G=(-ve)-T(+ve)=-ve-ve=-ve

A bottle of soda has a PH of 3.
BaLLatris [955]

Answer:

The new pH of the solution = 6

Explanation:

Given

pH of bottle of Soda is 3

As we know that

pH = -log [H+]

We will derive the hydrogen ion concentration when pH is 3

3 = - log [H+]

Taking anti-log on both the sides, we get -

H+ ion is equal to 10^{-3}

When the hydronuim ion concentration reduces by \frac{1}{1000} of the original concentration, the new hydrogen ion concentration becomes

\frac{1}{1000000} = 10^{-6}

The new pH is

= - log [ 10^{-6}]\\= 6

What are some of the techniques by which mixtures can be resolved into their components?
shtirl [24]
<span>Distillation, filtration, evaporation are some of the techniques by which mixtures can be resolved into their components.Distillation is the process of separating the component or substances from a liquid mixture by selective evaporation and condensation.Filtration is any of various mechanical, physical or biological operations that separate solids from fluids (liquids or gases) by adding a medium through which only the fluid can pass.Evaporation is a type of vaporization of a liquid that occurs from the surface of a liquid into a gaseous phase that is not saturated with the evaporating substance.</span>

When an apple falls from a tree, when does gravity act on the apple?
MrMuchimi
Gravitation Potential energy is converted into the Kinetic Energy, when it just reaches the ground. Some amount of energy is wasted in sound and heat energy when it strikes the ground. When the apple falls from the tree, it has some gravitational potential energy due to its height.
