Chemistry Mid Term Exam Version

.:6. Design a (hypothetical) experiment that adheres to the Scientific Method. Be sure to include all the necessary requirements at each step and give examples at all of the steps. Start with an observation, whether it’s real or made up, state the null hypothesis, and design an experiment (including an experimental and control group, random sampling, sample size, and reproducibility) that will allow the student to reject or fail to reject the hypothesis, and state the conclusion (20 points.)

•Be sure to write a detailed procedure for each lab design so that the same procedure can be followed accurately by anyone who reads it. Include details on the setup, the control of variables, and how the rate of each trial will be compared.

Refer as needed to material in Chapters 12 and 13. Read the instructions carefully and answer all questions clearly and concisely. Include examples to highlight your comments.

Guidelines: You may use all of the resources (e.g., textbook, other books, websites) available to you, EXCEPT FOR OTHER PEOPLE. Your work must be done individually. Any exams that appear similar in format and/or answers will be considered to have been done in a group setting. All such exams will receive a score of 0. Late exams will not be accepted for any reason. Any late exams will receive a score of 0. These policies will be strictly enforced.

• Please type you answers into this sheet. You must submit the worksheet two ways: 1) upload the worksheet as a Word document 2) cut and paste your answers into the student response box for the assignment.

Answer the questions below. When you are finished, submit this assignment to your teacher by the due date for full credit.

BEFORE CONDUCTING THE EXPERIMENT - You should already have submitted to your teacher an EXCELLENT Investigation Design that included:

You have been struggling with the contents of CHEM 200. It is very important for you to work more closely and frequntly with your Achieve tutor for this class. Please, follow your CHEM 202 intructor's advice and go to the tutoring sessions offered by Department of Chemestry to support the work you do at Achieve.

I learned that mass and volume work together to find the

Please make a copy of this document and submit it to classroom. Mrs. DeLucia will want a copy as well. You must come up with a different answer for each question.

The PH describes how basic or acid a substance is. The greater the PH the more basic the substance will be, but the lower the PH the more acid the substance will be. A PH of 7 is considered neutral and a PH higher of 7 is basic, a PH lower than 7 is acid.The importance of the PH of water is that it determines the biological life that can develop on that specific area. Pure water has a neutral PH of seven but this factor can vary as different chemicals are added to the water, making it more acid or basic.

Please complete this worksheet by typing answers into the spaces under the questions asked. This worksheet is worth 25 points. Place it in the appropriate dropbox when you are finished. I have enabled the originality check. Do not cut and paste or directly quote from the text or other sources. If the originality check gives a score above 50% you will be asked to redo the assignment.

A second design is quantitative research. This analysis engages mathematical models, theories, and hypothesis to examine cause and effect. It shows the relationship between data and observation through measurements. Control groups are used with

The experimental design used for this experiment is a between group design. A between group design is an experiment that includes two or more groups of participants being tested at the same time.
