Answer:

4 ATOME nitrogen in the formula

There are  20 nitrogen atoms in the chemical formula mentioned.

What is chemical formula?

Chemical  formula is a way of representing the number of atoms present in a compound or molecule.It is written with the help of symbols  of elements. It also makes use of brackets and subscripts.

Subscripts are used to denote number of atoms of each element and brackets indicate presence of group of atoms. Chemical formula does not contain words. Chemical formula in the simplest form  is called empirical formula.

It is not the same as structural formula and does not have any information regarding structure.It does not provide any information regarding structure of molecule as obtained in structural formula.They are used to describe the chemical reactions.

There are four types of chemical formula:

1)empirical formula

2) structural formula

3)condensed formula

4)molecular formula

Which two parts are needed to make a neutral atom of nitrogen A. Electron clouds with a total of 14 electrons B. Electron cloud is a total of seven electrons C. A nucleus with seven protons and seven neutrons D. A nucleus with three protons and four neutrons

Answers

Answer:

B. Electron cloud is a total of seven electrons

C. A nucleus with seven protons and seven neutrons

Explanation:

An atom is consist of three subatomic particles: electron, proton, and neutron. Proton are positively charged particles and neutron have neutral charge, they both are present inside the nucleus in the center of the atom whereas electrons are negatively charged and surround the nucleus in a definite orbit.

Nitrogen is an element with 7 electrons in its outer orbit. As electrons are negatively charged so nitrogen atom will require 7 protons inside the nucleus to form a neutral atom of nitrogen. So, A neutral atom of nitrogen will consist of 7 electrons and 7 protons.

As, neutron has neutral charge so it will not affect the composition of neutral atom of nitrogen.

Hence, the correct options are:

"B. Electron cloud is a total of seven electrons

C. A nucleus with seven protons and seven neutrons ".

B and C

Chelsea adds a 65% acid solution to 25 milliliters of a solution that is 30% acid. How much of the 65%
acid solution should be added to create a solution that is 40% acid?

Answers

Answer:

10 ml

Explanation:

The concentration of the acid solution Chelsea adds to the 25 milliliters of 30% acid solution = 65%

The concentration of the acid solution Chelsea requires = 40%

The volume, X, of the 65% acid solution required is given as follows;

65% × X + 30% × 25 = 40% × (25 + X)

As fractions, we have;

0.65 × X + 0.3 × 25 = 0.4 × (25 + X)

0.65·X + 7.5 = 10 + 0.4·X

0.65·X  - 0.4·X = 10 - 7.5

0.25·X = 2.5

X = 2.5/0.25 = 10

X = 10 ml

The volume of the 65% acid that should be added to create a solution that is 40% acid = 10 ml.

Autism is a disability that results from a disorder in the central nervous system. It has been speculated that the increasing number of cases of autism in recent years is due to the increase in the number of vaccinations given to young children. What might be another possible explanation for this phenomenon?

Answers

Answer:

Explanation:

As described in the question, autism is a disability that arises from a disorder in the central nervous system which is actually characterized by abnormality in the brain structure and then function. Autism is known for symptoms such as challenges with communication and interaction and some obsessive behaviors. While there is generally no known scientific cause for autism but trends have suggested that vaccination in young children causes autism.

However, genes could also be involved in this phenomenon because there have been reports of unusual genetic sequence in children that have autism. Hence, there is a possibility that vaccination actually triggers this genetic sequence which is then expressed as autism in the children.

Please note this isn't a scientific fact and just a possibility as requested in the question.

A brick delivery truck parks on a roadside scale that measures 4 m by 6 m. If the brick truck weighs 60 000 N, what pressure does the scale put on the spring below?

Answers

Explanation:

Area = Length × Breadth

A = 4 × 6

A = 24m square/ 24m sq.

Force = Pressure × Area

Force = 60,000 N/ 60,000 Newton

Pressure = Force/ Area

P = 60,000/24

P = 2500 Pa

A piece of aluminum has a mass of 12.0 g. When it is placed into a graduated

of aluminum?
0 2.66667g/ml
O 2.67 g/mL
O 2.667g/mL
O 2.7 g/mL

Answers

Answer:

The answer is 2.7 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 = 12 g

volume = final volume of water - initial volume of water

volume = 18.5 - 14 = 4.5 mL

So we have

[tex]density = \frac{12}{4.5} \\ = 2.66666666...[/tex]

We have the final answer as

2.70 g/mL
