What is the net charge of a nitrogen atom with 8 electrons

Answers

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

is pepperoni pizza an element, compound,
heterogeneous mixture, or homogeneous mixture?

Answers

Pepperoni pizza is a heterogeneous mixture because you can see the ingredients.

Pepperoni pizza is a heterogeneous mixture. Therefore, option C is correct.

A heterogeneous mixture is a type of mixture that consists of visibly different substances or phases that are not uniformly distributed. In a heterogeneous mixture, the different components can be easily distinguished and separated. The composition and properties of the mixture can vary at different locations within the mixture.

In a heterogeneous mixture, the substances do not blend together at the molecular level, unlike in a homogeneous mixture where the components are uniformly distributed.

B. There are 40 particles inside the nucleus and 18 particles outside the nucleus.
C. There are 40 particles inside the nucleus and 40 particles outside the nucleus.
D. There are 40 particles inside the nucleus and 22 particles outside the nucleus.

Answers

Answer:

A

Explanation:

Argon atom is a noble gas. In argon atom, there are 18 particles inside the nucleus and 18 particles outside the nucleus. Thus, the correct option is A.

What is Argon atom?

Argon is a non-metal element. It belongs to the group 18 (VIIIa) of the modern periodic table of chemical elements. This group is also called the noble gases group of the periodic table.

The argon atom is a noble gas which is made up of 18 protons and 18 electrons which are present inside the nucleus and outside the nucleus of the atom, respectively. The atom contains eight electrons in its outermost shell. Argon is a colorless and an odorless gas under the normal conditions. When argon is activated by the treatment of a high-voltage electric field, it emits a violet-colored light.

Therefore, the correct option is A.

Why do atoms always contain the same number of electrons and protons?

Answers

Answer:

An electron is a negatively charged subatomic particle and a proton is a positively charged subatomic particle. Positive charge(s) attract negative charge(s) and vice versa. The proton and neutron stay together and attract one another to give the atom an overall charge of zero (neutral). Which is the charge of an atom. When there is an unequal number of protons and neutrons an ion is formed. If the number of protons are more than the electron, a positively charged ion called cation is formed. On the other hand, if the number of electrons are more than the protons a negatively charged ion called anion is formed.

Answer:

When an atom has an equal number of electrons and protons, it has an equal number of negative electric charges (the electrons) and positive electric charges (the protons). The total electric charge of the atom is therefore zero and the atom is said to be neutral. ... Chemically, we say that the atoms have formed bonds.

6. An alloy of iron contains 75.0% iron and 25.0% other elements. How many grams of iron are present in 150. g of the alloy?

Answers

Answer:

108.5

Explanation:

half of 150 is 75 and half of that is 32.5. Add that to 75 and you'll get your answer

112.5 g of iron is present in the alloy.

From the question given above, the following data were obtained:

Percentage of iron (Fe) = 75%

Percentage of other elements = 25%

Mass of the alloy = 150 g

Mass of iron (Fe) =?

The mass of the iron present in the alloy can be obtained as follow:

[tex]Percentage = \frac{mass of element }{total mass }\\\\[/tex]

75% = [tex]\frac{mass of Fe}{150}[/tex]

[tex]0.75 = \frac{mass of Fe}{150}\\\\[/tex]

Cross multiply

Mass of Fe = 0.75 × 150

Mass of Fe = 112.5 g

Therefore, 112.5 g of iron is present in the alloy.

Calculate the number of moles for 12.044*10^23 number of helium atoms

Answers

Answer:

Explanation:

number of moles=number of particle (atoms)/avogadro number (NA)

we know that avogadro number is equal to 6.23*10^23

given number of atoms=12.044*10^23

therefore

moles=12.044*10^23/6.23*10^23=1.9=2

If a substance has a mass of 12.50 g and takes up 3.4 mL of space, what is the density?

Answers

Answer:

The answer is

3.68 g/mL

Explanation:

The density of a substance can be found by using the formula

[tex]density = \frac{mass}{volume} [/tex]

From the question

mass of substance = 12.50 g

volume = 3.4 mL

The density of the substance is

[tex]density = \frac{12.50}{3.4} \\ = 3.676470588...[/tex]

We have the final answer as

3.68 g/mL

A scientist grew bacteria on gel in her lab.
She wanted to find out if bacteria would grow faster on gel A or gel B.
she placed a few bacteria on gel A and a few on gel B.
After 24 hours, she observed how many bacteria were present.
Identify the independent and dependent variables.​

Answers

Answer:

The independent variable is type of gel and the dependent variable is the number of bacteria.

Explanation:

An experiment generally tests how one variable is affected by another. The affected variable is called the dependent variable. In the plant experiment shown above, the dependent variable is plant growth. The variable that affects the dependent variable is called the independent variable. In the plant experiment, the independent variable could be fertilizer—some plants will get fertilizer, others will not. The scientists change the amount of the independent variable (the fertilizer) to observe the effects on the dependent variable (plant growth). An experiment needs to be run simultaneously in which no fertilizer is given to the plant. This would be known as a control experiment. In any experiment, other factors that might affect the dependent variable must be controlled. In the plant experiment, what factors do you think should be controlled? (Hint: What other factors might affect plant growth?)
