Explanation:

<u>Problem</u>:

In a gender based experiment, the blood pressure of different ages of men is been checked and recorded to determine if there is any correlation. What will be the independent, dependent and controlled variables?

<u>Answer</u>:

A controlled variable is the variable that is left constant throughout the course of an experiment. The controlled variable here is the gender.

A dependent variable is the variable that is been determined or measured during the course of an experiment. The dependent variable here is the blood pressure.

An independent variable is the variable that is intentionally or decidedly altered during the course of an experiment. The independent variable here is the age.

Complete and balance the following equations. If no reaction occurs, write NR:(d) ClF(g) + F₂(g) →
kumpel [21]

A reaction occurs between the two gases Chlorine monofluoride (ClF) and Fluorine (F₂) when they are added together and as a result of the reaction a compound named, Chlorine trifluoride (ClF₃) is formed.

The reaction which occurs by addition of Chlorine monofluoride (ClF) and Fluorine (F₂) is as follows -

ClF (g) + F₂ (g) = ClF₃ (l)

When one molecule of Chlorine monofluoride (ClF) reacts with one molecule of Fluorine (F₂) gas, both the gases react together to form one molecule of Chlorine trifluoride (ClF₃) which is a liquid. Therefore, the above reaction is already balanced.

Chlorine trifluoride (ClF₃) is a greenish-yellow liquid which acts as an important fluorinating agent and is also an interhalogen compound (compounds that are formed by mixing two different halogen compounds together). Other than it's liquid state ClF₃ also can exist as a colorless gas. This compound ClF₃ is a very toxic, very corrosive and powerful oxidizer used as an igniter and propellent in rockets.

What is the net charge of a nitrogen atom with 8 electrons
DaniilM [7]

Answer:

– 1

Explanation:

From the question given above, we obtained the following:

Electron = 8

Net charge of nitrogen =.?

Nitrogen has atomic number of 7. This also means that nitrogen has 7 proton because atomic number of an element is the equal to number of protons in the atom of the element.

Thus, we can obtain the net charge of nitrogen with 8 electrons by calculating the difference between the protons and electrons of the nitrogen atom. This can be obtained as follow:

Proton = 7

Electron = 8

Net charge = Proton – Electron

Net charge = 7 – 8

Net charge = – 1

Therefore, the net charge of the nitrogen atom with 8 electrons is – 1
