Our solar system consists of the sun, planets, moons, asteroids, rock particles, dust, and gases that orbit the sun. From a scientific perspective, which makes the solar system a system?

For n = 3, the possible orbitals are:

• 3s orbital

• 3p orbitals

• 3d orbitals

What are the possible orbitals

3s orbital: The 3s orbital is spherical in shape and can hold up to 2 electrons.

3p orbitals: The 3p orbitals have a dum/bb/ell shape and consist of three individual orbitals: 3px, 3p/y, and 3pz. Each of these orbitals can hold up to 2 electrons, so the total capacity of the 3p sublevel is 6 electrons.

3d orbitals: The 3d orbitals have complex shapes and consist of five individual orbitals: 3dxy, 3dxz, 3dyz, 3dx2-y2, and 3dz2. Each of these orbitals can also hold up to 2 electrons, resulting in a total capacity of 10 electrons for the 3d sublevel.

In summary, for n = 3, the possible orbitals are 3s, 3p (3px, 3py, 3pz), and 3d (3dxy, 3dxz, 3dyz, 3dx2-y2, 3dz2).

Answer:The n = 3 shell, for example, contains three subshells: the 3s, 3p, and 3d orbitals. There is only one orbital in the n = 1 shell because there is only one way in which a sphere can be oriented in space.

9.75 x 10^5

A number in scientific notation has the form a x 10^b where

• a is the coefficient

• b is the exponent

Here are the steps to convert a number greater than 1 to scientific notation.

a) Find the coefficient

Put the decimal point after the first digit and drop the trailing zeroes

9.75 000

The coefficient is 9.75.

b) Find the exponent

Count the number of digits after the first digit.

In 975 000 there are five digits after the 9. Therefore, the exponent is 5.

c) Write the number

We write 975 000 as 9.75 x 10^5.

Answer:

• The hydrogen exist as a liquid at -253 degree C.

Explanation:

• Hydrogen is found as a molecular form H2. In order to become liquid , it must be cooled below its critical temperature. It become liquid at -253 degree C or 423.17  degree F or 20.8 K.

• So hydrogen become liquid at -253 degree Celsius.

Answer:

19.264×atoms are present in 3.2 moles of carbon.

Explanation:

It is known that one mole of each element is composed of Avagadro's number of atoms. This is same for all the elements in the periodic table.

So, as 1 mole of any element = Avagadro's number of atoms = 6.02× atoms

It is as simple as understanding a dozen of anything is equal to 12 pieces of that object.

As here the moles of carbon is given as 3.20 moles, the number of atoms in this mole can be determined as below.

1 mole of carbon = 6.02 × atoms

Then, 3.20 moles of carbon = 3.20 × 6.02 × atoms

Thus, 19.264×atoms are present in 3.2 moles of carbon.

Answer:

47 mL

Explanation:

By the image, the beaker graduation will from 45 from 50 mL, passing by 5 markings. So each mark has 1 mL. To read the volume, we have see the meniscus, which is the concave superficie of the liquid. The meniscus is above the second mark, so it passed 2 mL from the 45 line, the volume is 47 mL.
