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

Imagine you are about to investigate what happens when sodium and potassium are mixed together. Before you begin your experiment
inessss [21]

Explanation:

Potassium and Sodium are both metals on the periodic table. Both elements are found on the s-block of the table. Therefore, it is not possible for both of them to combine to form a compound.

For a compound to form two elements must combine in a definite order to given  single product.

The combination is facilitated by a loss, gain or sharing of electrons between two species. This leads to an attraction between the combining species.

Both Sodium and potassium would prefer to lose electrons and there is no reason for them to combine to form a compound.

A student collects 629ml of oxygen at 0.500at, the student collected 0.0337 moles. At what temperature did the student collect t
VashaNatasha [74]

Answer:

114 K

Explanation:

Given data

  • Volume of oxygen (V): 629 mL = 0.629 L
  • Pressure of oxygen (P): 0.500 atm
  • Moles of oxygen (n): 0.0337 mol
  • Temperature (T): ?

We can calculate the temperature at which the student collected the oxygen using the ideal gas equation.

P \times V = n \times R \times T\\T = \frac{P \times V}{n \times R}  = \frac{0.500atm \times 0.629L}{0.0337mol \times 0.0821atm.L/mol.K} = 114 K

The oxygen gas was collected at 114 K.

MrRissso [65]
A chemical property of soda ash is that it is an alkaline compound , of pH 11.6 in aqueous solution. The chemical name of soda ash is sodium carbonate. It is a sodium salt of carbonic acid and occurs as a white crystalline compound. It has a cooling alkaline taste. It can be found in the ashes of many plants. It is produced in large quantities from sodium chloride (common salt). It can be found as a mineral in mineral deposits of natron usually in seasonal lakes when the lakes dry up.
