Which of the following are also compounds? Select all that apply.


A.
H2O

B.
CuFeS2

C.
Cl

D.
Mg

E.
KCl

Water, copper ferrous sulphate and potassium chloride are the compounds. Therefore, option A, B and E are correct.

A chemical compound is a substance that contains atoms from many chemical elements bonded together by chemical bonds. It is made up of numerous similar molecules. Therefore, a molecule made up of only one type of atom is not a compound.

When various atoms are linked or chemically bound together to form molecules, the result is a compound. Water is an example of a compound. Due to the chemical bonding of two hydrogen atoms and one oxygen atom, water is known chemically as H2O.

Substances that cannot be divided into less complex substances with differing properties are known as elements. The periodic table is an arrangement of elements according to their properties. A molecule is made up of two or more atoms. Compounds are molecules made up of more than one element.

Thus, option A, B and E are correct.

Directions
Now that the lab is complete, it is time to write your lab report. The purpose of this guide is to help you write a clear and concise report that summarizes the lab you have just completed.
The lab report is composed of two sections:
Section I: Overview of Investigation
Provide background information.
Summarize the procedure.

Section II: Observations and Conclusions
Include any charts, tables, or drawings required by your teacher.
Include answers to follow-up questions.
Explain how the investigation could be improved.

To help you write your lab report, you will first answer the four questions listed below based on the lab that you have just completed. Then you will use the answers to these questions to write the lab report that you will turn in to your teacher.
You can upload your completed report with the upload tool in formats such as OpenOffice.org, Microsoft Word, or PDF. Alternatively, your teacher may ask you to turn in a paper copy of your report or use a web-based writing tool.
Questions


Section I: Overview of Lab
What is the purpose of the lab?
























What procedure did you use to complete the lab?
Outline the steps of the procedure in full sentences.
















Section II: Observations and Conclusions
What charts, tables, or drawings would clearly show what you have learned in this lab?
Each chart, table, or drawing should have the following items:
An appropriate title
Appropriate labels




























If you could repeat the lab and make it better, what would you do differently and why?
There are always ways that labs can be improved. Now that you are a veteran of this lab and have experience with the procedure, offer some advice to the next scientist about what you suggest and why. Your answer should be at least two to three sentences in length.











Writing the Lab Report


Now you will use your answers from the four questions above to write your lab report. Follow the directions below.

Section I: Overview of Lab
Use your answers from questions 1 and 2 as the basis for the first section of your lab report. This section provides your reader with background information about why you conducted this lab and how it was completed. It should be one to two paragraphs in length.


Section II: Observations and Conclusions
Use your answers from questions 3 and 4 as the basis for the second section of your lab report. This section provides your reader with charts, tables, or drawings from the lab. You also need to include answers to the follow-up questions and ways in which you would improve the lab.

Overall
When complete, the lab report should be read as a coherent whole. Make sure you connect different pieces with relevant transitions. Review for proper grammar, spelling, punctuation, formatting, and other conventions of organization and good writing.

How are mixtures and solutions different?

1.Unlike a solution, a mixture has density and will always sink in a liquid because mixtures lack buoyancy.

2.Unlike a solution, a mixture can dissolve completely in a liquid because the properties of the ingredients change.

3.Unlike a solution, a mixture is unable to change states of matter from a solid to a liquid or gas.

4.Unlike a solution, a mixture can easily be separated and each ingredient keeps its physical properties.
