Complete the sentences to identify the difference between a nonmetal atom and its anion.

In an anion, there are more *blank* than *blank*, giving the anion a *blank* charge.

In nonmetal atoms, the number of *blank* and *blank* are the same and there is a *blank* charge.

key bank:

- a positive

- no net

- electrons

- protons

- a negative

- neutrons

Answers

Answer:

more protons than neutrons and the number of electrons and blank are blank

Explanation:

The complete sentences that distinguish the difference between a nonmetal atom and its anion are as follows:

In an anion, there are more electrons than protons, giving the anion a negative charge. In nonmetal atoms, the number of protons and neutrons are the same and there is a negative charge.

What are Non-metals?

Non-metals may be defined as the type of chemical element that lacks the characteristics of a metal. They do not show any metallic attributes. But in the periodic table, they range from colorless gases to shiny and high melting point solids.

In the whole periodic table, elements are classified into three parts. They are metals, non-metals, and metalloids. Each classification has its own attributes and characteristic properties.

The non-metals significantly gain electrons due to their stronger nuclear charge and become negatively charged anions.

Therefore, the complete sentences that distinguish the difference between a nonmetal atom and its anion are appropriately described.

Okay.. so I guess this is how it goes:

1. Rainforest

Answer: The balanced equation will be

6H2 + N2 → 2NH3

Explanation:

First step is to balance nitrogen

ie, H2 + N2 → 2NH3

Second step is to balance hydrogen accordingly

ie, 6H2 + N2 → 2NH3

This is the perfect balanced equation.

What geometric shape is the carbon dioxide molecule? The Lewis structure for CO2 contains two double bonds.

Answers

Answer: Linear

Explaination: The central atom of a carbon dioxide molecule is carbon. Carbon is tetravalent which just means it has 4 valence electrons. Because the valence shell isn’t full, the carbon atom can bond with other atoms creating a total of 4 bonds. This then allows the carbon to double bond with 2 oxygen atoms. Now, the atoms in the CO2 molecule Don’t share the electrons evenly because of atomic number or proton count. Because oxygen has an atomic number of 6, carbon has an atomic number of 4, and opposites attract (referring to the positivity of the nucleus and the negativity of the shared electrons), the oxygen atoms will have a slightly negative charge (-) and the oxygen will have a slightly positive charge (+ ). Therefore, the slightly negative oxygen atoms repel creating that linear shape.

A girl stands on a bathroom scale. In metric units, the scale indicates that her weight is 42

Newtons. This means the force of gravity is pulling her feet onto the scale with a force of 42

Newtons. With what force does the scale push back up against her feet?

Answers

Answer:

The bathroom scale pushes her back 42 metric units, the same as her weight. Newton's 3rd law says that how much ever you push onto some object, it pushes back onto you with that same amount of pressure.
