Answer:
Usually give off heat energy
Explanation:
Exergonic reactions are the ones which are spontaneous. Spontaneous reactions are indicated by the negative change in the Gibbs free energy. In order to provide characteristics for an exergonic reaction, we need to define the Gibbs free energy in terms of the enthalpy change and the entropy change:

Here:
is the enthalpy change;
is the entropy change;
is the absolute temperature.
In order to achieve a negative value in the Gibbs free energy change, we should have:

This is true for all temperatures if:

The major term here is the change in enthalpy, notice that we wish the enthalpy change to be negative.
Negative enthalpy change corresponds to an exothermic reaction, the one which releases heat. This means exergonic reactions would usually give off heat.
The answer is a. 1.4

Interaction occurs when light goes into an object as heat energy is Absorbed light.
Absorbed light makes an object dark. Absorption of light is when the light is absorbed by the object and converts it into heat energy. The objects converts the wavelength of light into the larger wavelength of heat. this makes the object warmer and produced energy. Absorption depends on the frequency of light that is transmitted. The wavelength of light defined as the distance between the the two successive troughs of the the light wave.
Therefore, Interaction occurs when light goes into an object as heat energy is Absorbed light.

Answer:
2.48 atm
Explanation:
The partial pressure of the gas is equal to the product of the mole fraction and total pressure.
So,

Given that:-
Moles of A = 1.33 moles
Moles of B = 2.14 moles
Moles of C = 1.12 moles
Mole fraction of B can be calculated as:-

Total pressure = 5.28 atm
Thus, partial pressure of gas B = 0.47 x 5.28 atm = 2.48 atm
Because of the wind and the cold from ur breath
