He because nitrogen and ozone is a molecule but helium is atom
frez [133]3 years ago

<u>Ans: Thus, O3 and He are not the formulas for diatomic. Only N2 is a diatomic</u>

A monatomic system consists of only a single element

A diatomic system consists of two elements

A polyatomic systems consists of more that two elements

1) N2: nitrogen molecule is composed of 2 N atoms. Hence it is a diatomic

2) O3: ozone is composed on 3 O atoms. Hence it is a triatomic (polyatomic)

3) He: Helium is  simply a monatomic

2C8H18 (1) + 2502 (g) --&gt; 16CO2 (g) + 18H2O (g)
Makovka662 [10]

Answer:

One gallon of octane produces approximately 7000 L of carbon dioxide.

Note:

I believe that the mass of octane should have been given as 2661 g. However, I understand that your instructor probably gave you this problem, so I will use 4000 g for the approximate mass of one gallon of octane. You can rework the problem on your own, substituting the correct masses of octane if you wish.

Step1. You must first determine the number of moles that are in 4000 g of octane, using the molar mass of octane. Step 2. Then you must determine the number of moles of carbon dioxide that can be produced by that number of moles of octane, based on the mole ratio between octane and carbon dioxide in the balanced equation. Step 3. Then use the ideal gas law to determine the volume in liters of carbon dioxide that can be formed.

How many liters of a 1.5 M solution can you make if you have .50 mol of KCl?
vaieri [72.5K]

Answer:

The answer to your question is 0.33 liters

Explanation:

Data

Volume = ?

Molarity = 1.5 M

number of moles = 0.5

Formula

Molarity = \frac{number of moles }{volume}

Solve for V

Volume = \frac{number of moles}{molarity}

Substitution

Volume = \frac{0.5}{1.5}

Simplification and result

       Volume = 0.33 l

Separating techniques - Chromatography
vodomira [7]

The method that can be used to separate the mixture is chromatography.

<h3>What is chromatography?</h3>

"Chromatography" is obtained form a Greek word which literarily means, color writing. It is a method of separation which is common in separating a mixture of pigments.

To obtain the colors used, two solvents are mixed and the sample ink is dissolved in the solvents then spotted on a thin layer and put into a TLC chamber then the chromatogram is allowed to develop.

The various components of the pigment will appear on the chromatogram and can be identified using spectrophotometry. The Rf values of each component can also be used to identify it.'
