Objectives(s):
In your own words, what is the purpose of this lab?
To teach me about chemical compounds
Hypothesis:
In this section, please include the if/then statements you developed during your lab activity. These statements reflect your predicted outcomes for the experiment. If you combine two certain compounds, then it will make a new compound.
Procedure:
The materials and procedures are listed in your virtual lab. You do not need to repeat them here. However, you should note if you experienced any errors or other factors that might affect your outcome. Using your summary questions at the end of your virtual lab activity, please clearly define the dependent and independent variables of the experiment.
Data:
Record the composition of each of your compounds below. Be sure to include the number of atoms for each element. An example has been supplied for you.

Conclusion:
Your conclusion will include a summary of the lab results and an interpretation of the results. Please answer all questions in complete sentences using your own words.
Using two to three sentences, summarize what you investigated and observed in this lab. I investigated how chemical compounds work and what to use to put them together.
Why do you believe knowing how elements and compounds react together is essential in everyday matters? So, you can cook and stop injuries, these two things happen a lot in day-to-day life.
Some elements are more "reactive" than other elements; why do you think this is? Because certain elements in the compound may react more to fire or water and many other elements.
Choose one of the compounds from the table and explain how you know the numbers of atoms in your formula. Because if you add all the atoms, put in that’s the total amount. For example, water has one hydrogen atom and one oxygen atom, so water has two atoms.
Is it possible for two different compounds to be made from the exact same two elements? Why or why not? With a limited number of elements (less than 120 are known), does this mean we also have a small number of compounds, or do we have many compounds in this world? Yes, it is possible like water and hydrogen peroxide. The formula of water is H20 but hydrogen peroxide has one more oxygen-H202.
Explanation:
, then the bond is non-polar.
, then the bond will be covalent.
, then the bond will be ionic.
