What is one effect of the uneven heating of Earth caused by the Sun? (Answer with a 5 sentence paragraph)

Chemistry
1 answer:
Papessa [141]3 years ago
7 0

Answer:

Albedo

Explanation:

Usually when we talk about uneven heating of the Earth's surface we are discussing convection. The uneven heating results in some of the atmosphere to be warmer than other parts and changes in volume and pressure which result in updrafts and can cause thunderstorms and other violent weather. The cause of this is the reflectiveness of the surface of the Earth at that point (the albedo) and the angle that the sun's rays strike it at. A field covered with snow and ice is going to be much more reflective than a black top asphalt parking lot. As such the parking lot absorbs much more shortwave radiation from the sun and gets much warmer.

Be sure to answer all parts. Dinitrogen difluoride, N2F2, is the only stable, simple inorganic molecule with an N=N bond. The co
ASHA 777 [7]

(a) The molecular shapes of cis and Trans forms of N2F2 are-


b) There is EN difference between N atom and F atom. Hence the molecule will have a bond dipole.

In Cis form two fluorine atoms are on the same side of N N bond. Hence, bond moment in N2F2 cis form) do not cancel each other. Thus the cis form is polar.

In the trans form two fluorine atoms are on the opposite side of N-N bond. Bond moment of NF cancels each other.

Thus: trans N2F2 is non polar molecule.

Dolomite is a carbonate of magnesium and calcium. Analysis shows that 7.81 g of dolomite contains 1.70 grams of Ca. Fluorite is
andrew11 [14]

Answer:

The richer source of calcium is fluorite.

Explanation:

Percentage of element in compound :

=\frac{\text{mass of element}}{\text{Mass of compound}}\times 100

1. Dolomite is a carbonate of magnesium and calcium:

Given mass of dolomite = 7.81 g

Mass of calcium present in given mass of dolomite = 1.70 g

Percentage of calcium in Dolomite:

=\frac{1.70 g}{7.81 g}\times 100=21.77\%

2. Fluorite is a mineral of calcium and fluorine:

Given mass of fluorite = 2.76 g

Mass of fluorine present in given mass of fluorite = 1.34 g

Percentage of fluorine in fluorite :

=\frac{1.34 g}{2.76 g}\times 100=48.55\%

Percentage of calcium in fluorite = 100% - 48.55 % = 51.45%

Percentage of calcium in fluorite > Percentage of calcium in Dolomite

51.455 > 21.77%

So, the richer source of calcium is fluorite.
