(SOMEONE PLS HELP I NEED THIS DONE BY 7:30PM) Compounds Lab Report Instructions: In this virtual lab you will build chemical compounds from known elements. Record your hypothesis and compound results in the lab report below. You will submit your completed report to your instructor. Note: If you cannot complete this lab as directed, please contact your instructor for assistance. Name and Title: Include your name, instructor's name, date, and name of lab. Objectives(s): In your own words, what is the purpose of this lab? 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. 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. Compound NameChemical FormulaSodium (Na) AtomsCalcium (Ca) AtomsHydrogen (H) AtomsOxygen (O) AtomsCarbon (C) AtomsChlorine (Cl) AtomsEx: Sodium hypochloriteNaClO100101 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. Why do you believe knowing how elements and compounds react together is essential in everyday matters? Some elements are more "reactive" than other elements; why do you think this is? Choose one of the compounds from the table and explain how you know the numbers of atoms in your formula. 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 a large number of compounds in this world?

Objectives(s):

to build chemical compounds from known elements

Hypothesis:

if I use oxygen hydrogen and carbon then I can make five new compounds in four minutes

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.

Compound Name Chemical Formula Sodium (Na) Atoms Calcium (Ca) Atoms Hydrogen (H) Atoms Oxygen (O) Atoms Carbon (C) Atoms Chlorine (Cl) Atoms

Ex: Sodium

hypochlorite NaClO 1 0 0 1 0 1

Water H20 o 0 1 2 0 0

Glucose C6H12O6 0 0 12 6 6 0

Formic/methanoic acid HCOOH 0 0 2 2 1 0

Butanoic Acid C3H7COOH 0 0 8 2 4 0

Carbon Dioxide C02 0 0 0 2 1 0

Carbon Monoxide CO 0 0 0 1 1 0

Fructose C6H12O6 0 0 12 6 6 0

0 0 0

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.

I found as many combinations of carbon hydrogen and oxygen as possible

If there is a job that combines elements you would be doing that every day making it an every day matter

elements are like people, they are all different causing them to react differently and be more reactive

H20 has four because there are 2 oxygen and one hydrogen because of the numbers in the name of the compound

Yes because two elements can form two different types of bonds causing different outcomes

Answer from: Quest

1.from liquid state to gaseous state is evaporation 3.solid to liquid is melting 5. solid to gaseous state is sublimation 6. gas to solid state is decomposition 7. a change of state is known as the states of matters

Answer from: Quest

answer: a tank of height h is filled with water and sits on the ground. water squirts from a hole at a height y above the ground and has a range r. for two y values, 0 and h, r is zero. determine the value of y for which the range will be a maximum.
