The atoms and molecules in a gas are in constant motion. Temperature is a measure of this motion. How are these related? As temp
Sedaia [141]

Here we have to choose the correct statement on the effect of temperature on the motion of the molecules and atoms of a gas.

As the temperature increases the molecules and atoms move faster.

As per the kinetic theory of gas molecules and atoms the kinetic energy (K.E.) of the atom or molecules is related to temperature by the equation

K.E. = \frac{3}{2}kT ( k = Boltzmann constant, T = temperature.

Thus as the temperature increases the K.E. increases thus the atom or molecules move faster.

With the decrease of temperature the movement of the atoms or molecules will be less and they will be near to each other.

The increment of temperature increase the K.E. thus the atoms or molecules move apart from each other.

With the decrease of temperature the movement of the atoms or molecules decreases.

When hydrogen ................................... a CIS formation exist.
There are two types of formation which are possible in fatty acids, these are CIS and TRANS configurations.
A fat is described as a CIS fatty acid if its hydrogen atoms are lying on the same side of the carbon carbon double bonds. A fat is said to be a trans fatty acid, if the hydrogen atoms in its molecules are lying on the opposite sides of the carbon bonds.

A chemist fills a reaction vessel with 9.47 atm nitrogen monoxide (NO) gas, 2.61 atm chlorine (C12) gas, and 8.64 atm nitrosyl c
lys-0071 [83]

Answer:

\Delta _rG=2832.2J/mol

Explanation:

Hello,

In this case, the Gibbs free energy of that reaction is computed by computing the equilibrium constant as:

K=\frac{p_{NOCl}^2}{p_{NO}^2p_{Cl_2}} =\frac{8.64^2}{9.47^2*2.61}=0.319

Hence the Gibbs free energy:

\Delta _rG=-RTlog(K)=-8.314\frac{J}{mol*K}*298.15K*ln(0.319)\\\\\Delta _rG=2832.2J/mol

Best regards.

Sparrows with average-sized wings survive severe storms better than those with longer or shorter wings, illustrating?
8090 [49]

Sparrows with average-sized wings survive severe storms better than those with longer or shorter wings illustrates Stabilizing selection.

Stabilizing selection is a natural selection in which stabilized traits are selected rather than any extreme traits by the nature. Nature do not favors any drastic change in the traits over the years.

Stabilizing selection is often confused with or misunderstood as negative or purifying selection.

Stabilizing selection favors intermediate variants promoting survival of the species.

Average phenotype is selected and continuously dominates in coming generations.

This natural selection helps species to adapt stable phenotype for better survival rate.
