Answer:

A 3s orbital is at a greater average distance from the nucleus than a 2s orbital

Explanation:

As the principal quantum number n increases, the distance of the orbital from the nucleus increases. Hence if we consider the 2s and 3s orbitals, it is easy to see that the 3s orbital is at a greater distance from the nucleus than the 2s orbitals.

This is clearly seen when we plot the radial distribution against the distance from the nucleus. This enables us to visualize the region in space in which an electron may be found.

Answer: The equilibrium constant for $NO_2(g)\rightleftharpoons NO(g)+\frac{1}{2}O_2(g)$ equation is $1.36\times 10^{-7}$

Explanation:

The given chemical equation follows:

$2NO(g)+O_2(g)\rightleftharpoons 2NO_2(g)$

The value of equilibrium constant for the above equation is $K_{eq}=5.4\times 10^{13}$

Calculating the equilibrium constant for the given equation:

$NO_2(g)\rightleftharpoons NO(g)+\frac{1}{2}O_2(g)$

The value of equilibrium constant for the above equation will be:

$K'_{eq}=\frac{1}{\sqrt{K_{eq}}}\\\\K'_{eq}=\frac{1}{\sqrt{5.4\times 10^{13}}}\\\\K'_{eq}=1.36\times 10^{-7}$

Hence, the equilibrium constant for $NO_2(g)\rightleftharpoons NO(g)+\frac{1}{2}O_2(g)$ equation is $1.36\times 10^{-7}$

If South America were not there, explain how the direction of South equatorial current would be different

forsale [732]

Explanation:

South America land mass serves as a deflector for the South equatorial current. This deflection the current causes them to move in a different direction. If the Continent were not present the direction of the South equatorial current would not change and it would continue to flow in the west.

Simora [160]

The container with chalk powder will contain the least amount of water, because it absorbs water, but the containers with honey and cocunut oil will conserve their amount of water, because they will prevent the water evaporation (especially cocunut oil because it will be on the top side of the container).
