Describe and explain how petrol is separated from the mixture of hydrocarbons in crude oil?

Answers

Answer 1

Answer: It's an exciting and interesting process but those 5 points aren't worth a decent answer. The whole process is called fractioned distillation where different temperatures are reached, transforming the crude oil in gas. After being hit by a cold source it colds becoming different hydrocarbons depending on the temperatures.

Which formula represents a polar molecule?
(1) O2
(2) CO2
(3) NH3
(4) CH4

Answers

Answer: Option (3) is the correct answer.

Explanation:

A molecule is polar when the net dipole moment of molecule is zero. When an electronegative atom is attached to an electropositive atom then the electronegative atom pulls the shared pair of electrons more towards itself.

As a result, the movement of electrons is more towards the electronegative atom and the dipole moment becomes zero. This will also induce partial positive and partial negative charge on electropositive and electronegative atom.

On the other hand, $O_(2), CO_(2), and CH_(4)$ are covalent compounds and does not have a net zero dipole moment.

Thus, we can conclude that out of the given options $NH_(3)$ represents a polar molecule.

What is the mass percent of nitrogen in ammonium carbonate, (NH4)2CO3?

Answers

In order for you to calculate for the mass of ammonium carbonate, you need to know the molar mass of it and the nitrogen atoms in the compound. Ammonium carbonate has a molar mass of 96.08 grams per mole. There are two nitrogen atoms in ammonium carbonate which is equal to 28.02 grams per mole. Divide the molar mass of nitrogen to the ammonium carbonate, 28.02/96.08 x 100, we get 29.16wt% nitrogen.

Answer:

29.16%.

Explanation:

You can determine the mass percent, or how much of the total mass of ammonium carbonate is nitrogen, by first determining the mass of nitrogen and the mass of the total compound.

1. the mass of nitrogen in this compound is 2 x 14.007, or 28.014.

2. the mass of ammonium carbonate is 96.09 grams.

To find the percentage of nitrogen in the overall mass of ammonium carbonate, simply divide the mass of nitrogen by the mass of ammonium carbonate and multiply by 100:

28.014/96.09 x 100 ....................... 29.16%.

What is the correct way to represent 5600 L using scientific notation?–5.6 mc031-1.jpg 103 L
–5.6 mc031-2.jpg 10–3 L
5.6 mc031-3.jpg 10–3 L
5.6 mc031-4.jpg 103 L

Answers

To answer this you first must know that the value before the x10^n must be below 10 and equal or greater than 1. All the choices are valid with respect to this law. Next, 5600L is positive canceling the first 2 choices. The last value is the answer since multiplying a value with 10^3 makes a larger number or moves the decimal place to the right 3 places.

The correct way to represent 5600 L using scientific notation is written as 5.6 x 10³ L.

What is Scientific notation?

Scientific notation or standard form is method of representing large numbers in more condensed form using power of ten.

The correct way to represent 5600 L using scientific notation is written as follows;

5600 L = 5.6 x 10³ L

Thus, the correct way to represent 5600 L using scientific notation is written as 5.6 x 10³ L.

What volume of a 2.5 M stock solution of acetic acid (HC2H3O2) is required to prepare 100.0 milliliters of a 0.50 M acetic acid solution?

Answers

To solve this we use the equation,

M1V1 = M2V2

where M1 is the concentration of the stock solution, V1 is the volume of the stock solution, M2 is the concentration of the new solution and V2 is its volume.

2.5 M x V1 = 0.50 M x .100 L

V1 = 0.02 L or 20 mL

Answer:

20 milliliters

20g of sugar is stirred into a beaker containing 100 g of water. After the sugar has completely dissolved, the solution is put on the scale. What is the mass of the solution ? help A) 20g B) 80g C) 100g D) 120g

Answers

The correct answer is: Option (D) 120g

Explanation:

We are given the following:

Mass of sugar = 20 g

Mass of water = 100 g

When sugar is completely dissolved into water, the mass of the solution will get:

mass-of-solution = mass-of-sugar + mass-of-water

mass-of-solution = 20 + 100

mass-of-solution = 120 g (Option D)

Its D I Think because mass cant really disappear
