Answer:

Answer:K = 5.04 × 10⁵²

Explanation:

The relation between equilibrium constant and emf is:

E^{0}_{cell} = \frac{0.0592}{n}  (logK)

Given

E^{0}_{cell} = 1.56

n = 2 (for the given reaction)

Putting values

1.56=\frac{0.0592}{2}(logK)

logK=52.70

K = 5.04 × 10⁵²

Because rusting is a spontaneous process under standard conditions, which of the following is a correct conclusion about the pro
lawyer [7]

The correct conclusion about the process is that "DeltaG" is negative and the product of temperature and "DeltaS" is greater than "DeltaH". That is option C

Spontaneous reaction are natural reactions that occurs without depending on energy from external sources.

A typical example of a spontaneous reaction is the rusting of iron.

To know if a reaction is spontaneous, second law of thermodynamics is used through Gibbs free energy.

At standard conditions ( constant temperature and pressure), Gibbs free energy(G) is equal to enthalpy change(ΔH) minus product of temperature(T) and the entropy change (ΔS) of the system.

That is, ΔG =ΔH −TΔS,

Entropy (S) is a measure of the degree of disorderliness of a system.

Enthalpy (H) is the heat of the reaction which is positive when heat is given out or negative when heat is absorbed.

From the formula, when ∆G is less than 0, the reaction is said to be spontaneous.

For ∆G to be less than 0, this means ∆H(DeltaH) is less than 0 and T∆ S( product of temperature and "DeltaS") is greater than 0 to achieve a negative value for ∆G(DeltaG)

Therefore, DeltaG" is negative and the product of temperature and "DeltaS" is greater than "DeltaH".

1 loop in the primary coil and 8 loops in the secondary. If the secondary voltage is 120 V, what must be the primary voltage
Jet001 [13]

Answer:

V_{p} = 15 V

Explanation:

<u>Given the following data;</u>

Number of loops in primary coil, Np = 1 loop.

Number of loops in secondary coil, Ns = 8 loops

Voltage in secondary coil, Vs = 120V

To find the voltage in the primary coil, Vp;

Transformer ratio is given by the formula;

\frac{V_{p}}{V_{s}} = \frac{N_{p}}{N_{s}}

Making Vp the subject of formula;

V_{p} = \frac{N_{p}}{N_{s}} * V_{s}

Substituting into the equation, we have;

V_{p} = \frac{1}{8} * 120

V_{p} = \frac{120}{8}

V_{p} = 15 V

Therefore, the voltage in the primary coil, Vp is 15 Volts.

How many moles of water are produced when 5 moles of hydrogen gas react with 2 moles of oxygen gas?
Marysya12 [62]

4 moles of water are produced

Explanation:

  • 4 moles of water are produced when 5 moles of hydrogen is reacted with 2 moles of oxygen gas
  • The balanced equation given is when 2 moles of hydrogen reacts with 1 mole of oxygen and it forms 2 moles of water.
  • The equation we have to solve is the 5 moles of hydrogen is reacting with 2 moles of oxygen gas, we can write the equation as 5H_{2} +2O_{2} -->  4H_{2} O + H_{2}
  • This is the balanced equation when 5 moles of hydrogen reacts with 2 moles of oxygen. The balanced equation means the number of hydrogen atoms and oxygen atoms on both sides would be equal in number.
