<u>Answer:</u> The correct answer is Option C.

<u>Explanation:</u>

There are two types of energy sources. They are:

  • <u>Renewable sources of energy:</u> This is defined as the source which does not get depleted or destroyed when they are used. For Example: Wind, solar, geothermal etc..
  • <u>Non-Renewable sources of energy:</u> This is defined as the source which gets depleted or destroyed when they are used. They are present in limited amount. For Example: Coal, natural gas, oil etc..

Hence, the correct answer is Option C.

What is the frequency of light that is associated with green in the visible spectrum with a
Delicious77 [7]

Answer:

5.5 × 10^14 Hz

Explanation:

The wavelength can be represented using the formula;

λ = v/f

Where;

λ = wavelength (m)

v = speed of light (3 × 10^8m/s)

f = frequency (Hz)

According to this question, a light associated with the visible spectrum has a wavelength of 550 nm.

550nm = 550 × 10^-9m

f = v/λ

f = 3 × 10^8 ÷ 550 × 10^-9

f = 0.0055 × 10^ (8+9)

f = 0.0055 × 10^17

f = 5.5 × 10^14 Hz

The frequency is 5.5 × 10^14 Hz

Q#1 Give a combination of four quantum numbers that could be assigned to an electron occupying a 5p orbital.
Gnesinka [82]

Answer:

For an electron in 5p orbital

5,1,-1,+1/2

For an electron in 6d orbital

6,2,-2,+1/2

Explanation:

The term quantum numbers refers to a set of values that can be used to determine the region in space where it is likely to find an electron. This region in space where there is a high probability of finding an electron is known as an atomic orbital. An atomic orbital is actually a wave function according to the Schrödinger wave equation.

There are four quantum numbers used in describing an atomic orbital: the principal quantum number (n), the orbital angular momentum quantum number also called azimuthal or subsidiary quantum number (l), the magnetic quantum number (ml), and the electron spin quantum number (ms).

For a 5p orbital;

n= 5, l= 1, ml= -1,0,1 ms= +1/2 or -1/2

For 6d orbital;

n= 6, l= 2, ml= -2,-1,0,1,2, ms= +1/2 or -1/2

Since we are requested to use a four quantum number description that can be assigned to an electron in these levels;

For an electron in 5p orbital

5,1,-1,+1/2

For an electron in 6d orbital

6,2,-2,+1/2

Quantitative is anything that is relating to a number value. Think “quantity”

Example:

1. There are 5 ml of water
2. There are 3 beakers
3. It takes 30 minutes for the reaction

Qualitative is about characteristics that can be described

Example

1. The liquid is green
2. The solution turned into a gas
3. Bubbles were produced
