What is an element? Arrow

Chemistry
1 answer:
Butoxors [25]2 years ago
7 0

Answer:

One arrow is positioned in each box according to Hund's Rule which tells us to maximise the number of unpaired electrons in orbitals of the same subshell, and, to give those electrons the same "spin" (parallel spin).

Which type of electromagnetic radiation had a lower frequency than infrared radiation
Alika [10]

Answer:

Radio waves

Explanation:

Radio waves, on the other hand, have the lowest energies, longest wavelengths, and lowest frequencies of any type of EM radiation. In order from highest to lowest energy, the sections of the EM spectrum are named: gamma rays, X-rays, ultraviolet radiation, visible light, infrared radiation, and radio waves.

An experiment in a general chemistry laboratory calls for a 2.00 M solution of HCL. How many mL of 11.9 M HCL would be required
Annette [7]

<u>Answer:</u> The volume of concentrated solution required is 42 mL

<u>Explanation:</u>

To calculate the molarity of the diluted solution, we use the equation:

M_1V_1=M_2V_2

where,

M_1\text{ and }V_1 are the molarity and volume of the concentrated solution

M_2\text{ and }V_2 are the molarity and volume of diluted solution

We are given:

M_1=11.9M\\V_1=?mL\\M_2=2.0M\\V_2=250mL

Putting values in above equation, we get:

11.9\times V_1=2.0\times 250\\\\V_1=42mL

Hence, the volume of concentrated solution required is 42 mL

How does the number of Carbon atoms per molecule affect the state at room temperature? Explain how this is similar or different
RSB [31]

Explanation:

There are three states of matter:

1) Solid: In this state, the particles lie closer to each other. there is a strong intermolecular force of attraction between the particles.

2) Liquid: In this state, the particles are at a certain distance to each other. There is an intermediate intermolecular force of attraction between the particles.

3) Gas: In this state, the particles are farther from each other. There is weaker  intermolecular force of attraction between the particles.

As the number of carbon atoms in a molecule increases, the number of particles increases and the particles will come closer to each other. Hence, the state of matter will shift towards the solid state.

Viscosity is defined as the tendency to resist the particles to flow. As, the number of carbon atoms increases, the Vander-Walls forces increases, the particles are closer to each other and Hence, the viscosity will increase.
