**__ Molar Mass Practice Worksheet __**

//Find the molar masses of the following compounds://

1) NaBr 1 mole of Na x 23 = 23 1 mole of Br x 80 = **103**

2) PbSO4 1 mole of Pb x 207.2 = 207.2 4 moles of O x 16 = **271.2**

3) Ca(OH)2 1 mole of Ca x 40 = 40 1 mole of O x 16 = 16 2 moles of H x 1 = **58**

4) Na3PO4 3 mole of Na x 23 = 69 1 mole of P x 31 = 31 4 moles of O x 16 = **164** 5) (NH4)2CO3 2 moles of N x 14 = 28 8 moles of H x 1 = 8 1 mole of C x 12 = 12 3 moles of O x 16 = **96**

6) C6H12O6 6 moles of C x 12 = 72 12 moles of H x 1 = 12 6 moles of Ox 16 = **180**

7) Fe3(PO4)2 3 moles of Fe x 55 = 165 2 moles of P x 31 = 62 8 moles of O x 16 = **355**

8) (NH4)2S 2 moles of N x 14 = 28 8 moles of H x 1 = 8 1 mole of S x 32 = **68**

9) Zn(C2H3O2)2 1 mole of Zn x 65 = 65 4 moles of C x 12 = 48 6 moles of H x 1 = 6 4 moles of O x 16 = **183**

10) AgF 1 mole of Ag x 108 = 108 1 mole of F x 19 = **127** Temperature difference  Materials: 1) Laptop 2) Bucket 3) Mud, sand, soil, dirt, rocks 4) Data table 5) Data logger - expand on this, because in reading this i do not understand what you want specificaly Method: Use some buckets and fill them with soil, dirt, rocks, sand and mud. Connect the Data logger to the laptop and start the program. Put the sensor into the ground and write down the tempeture difference every 2 min for 10 min. - this isnt much of a method you need to explain in greater detail Hypothesis: I predict that the material with the most air that is able to pass through will heat the slowest. _ Alright  Temp 70

The Scientific Method Adam Pitt 6/9/10

The scientific method is the process that all scientists use in an experiment. It consists of a hypothesis which is an educated guess. An observation or an experimentation. Then the data is analyzed and organized. If the experiment does not work try again you might have done some wrong ( doesn't make much sense) . Lastly draw your conclusion. The hypothesis is a statement that proposes a possible explanation to some fact or event. A hypothesis is a scientific guess. The experiment tests whether the hypothesis is true or false. It is important for the experiment to be a fair test. You do a fair test by making sure that you change only one factor at a time while keeping all the other conditions the same. The experiment should also be repeated several times to make sure that the first results weren't just an accident. ( thats good information) - needs more of an explanation with more steps , because i cant just follow a precedure with these little steps Once the experiment is complete, collect the measurements and analyze them to see if your hypothesis is true or false. Scientists often find that their hypothesis was false, so they will make a new hypothesis starting the entire process of the scientific method over again. Even if they find that their hypothesis was true, they may want to test it again. - good

The scientific method is used by coming up with a question or problem, coming up with an educated guess of what might happen in your experiment, doing the experiment, making observations and drawing the results. For the steps listed above each site I visited had different names and procedures for the scientific method. They also had different diagrams for the scientific method. - good explanation, you need to explain in a bit more detail and need to lengenth your answer and word it properly because it doesnt always make sense ( good) ﻿ abi :) Owen [] [] []  Temerature Difference Equipment Temp. Sensors Laptop Data logger Pen and paper Volunteers Gym mat Hypothesis The greater amount of exercise the volunteer does and the more difficult the exercise is the greater the skin temperature depending. Method 1. The volunteer places the skin temp sensor to an area of their choice. Then hold it there for 30 seconds. 2. Record the temp. 3. After this do 10 sit ups 4. Place the temp sensor back into the exact spot as before. 5. Repeat step 2 6. Wait 5 minuites 7. Do 20 sit ups 8. Repeat step 2, 4 and 6 9. Do 30 sit ups 10. Repeat step 2, 4 and 6 11. Do 10 push ups 12. Repeat step 2, 4 and 6 13. Do 20 push ups 14. Repeat step 2, 4 and 6 15. Do 30 push ups 16. Repeat step 2, 4 and 6 17. Do 10 step ups 18. Repeat step 2, 4 and 6 19. Do 20 step ups 20. Repeat step 2, 4 and 6 21. Do 30 step ups 22. Repeat step 2, 4 and 6
