Suna passes an electric current through a sample of clear, colorless, and odorless liquid. As the experiment continues, bubbles

form, and the volume of liquid decreases. Suna collects samples of two colorless, odorless gases that bubble out of the liquid. One of the gases burns. Neither the original liquid nor the other gas burns. Which is the best explanation of her results? A) The electric current changed some of the sample to gas even though the sample was not breaking down. Therefore, the original liquid is a compound.B) The electric current released a gas that was odorless and colorless, like the original sample. Therefore, the original liquid is an element.C) The sample was broken down by the electric current and formed a new substance that could burn. Therefore, the original liquid is a compound. D) The sample lost some of its volume, but the gas still had the same chemical makeup as the original sample. Therefore, the original liquid is an element.

Answer: option <span>C) The sample was broken down by the electric current and formed a new substance that could burn. Therefore, the original liquid is a compound.


The use of the electric current to decompose substances is called electrolysis.

The case presented is the same of the electrolysis of water: the electrical current decomposes the water (a compound) into the elements that form it: hydrogen (a gas that burns) and oxygen (a gas that does not burn).</span>

All molecules are compounds<br> True or false
Harrizon [31]

False (All compounds are molecules, but not all molecules are compounds. That is because a molecule can be made up of two atoms of the same kind, as when two oxygen atoms bind together to make an oxygen molecule. However, all compounds are made up of two or more different types of atoms.)

Write the full electron configuration of the Period 2 element with the following successive IEs (in kJ/mol):
Julli [10]

Answer:

Boron (B) is the element whose IE matches with our data.

Electronic Configuration of boron: 1s^22s^22p^1

Explanation:

Ionization Energy (IE):

It is the minimum amount of energy which is required to remove the lose electron. If the electron is closer to the nucleus then greater amount of energy is required to remove the electron.

If we look from left to right in a period, ionization energy increases due stability of valance shell.

From the data given to us:

IE₁ = 801

IE₂ = 2427

IE₃ = 3659

IE₄ = 25,022

IE₅ = 32,822

Boron (B) is the element whose IE matches with our data.

Electronic Configuration of boron: 1s^22s^22p^1

Boron has 5 electrons (3 in valance shell) that's why it has 5 Ionization Energies.
