# Hon Chemistry 9-6-22 ID of Unknown Lab

HONORS CHEMISTRY – Happy use your brain day!! Can you now use what you’ve learned about density? Who is going to be your spokesperson? When is your lab going to be due? Do you need two due dates???

Can’t wait to “watch” you work!

clear average is 1.48 g/cm^3

• S Skinner HC6 says:

actually 0.81 g/cm^3

2. R McCoy says:

i believe the clear blocks are gamma

Color Black

V=l^3
V= 12.20cm * 4.15cm * 1.30cm
V= 65.82cm^3

m= 65.96g

D= m/V
D= 65.96g/ 65.82cm^3
D=1.00 g/cm^3

Averaged Density= 0.99 g / cm^3

Block name Beta

Milky
Width-7.32cm
Height-1.25cm
Length-4.50cm
Volume= l x w x h
Volume=(4.50cm)x(7.32cm)x(1.25cm)
Volume- 41.175cm^3
Mass=36.60g
Density=Mass/volume
Density=36.60g/41.175cm^3=0.889g/cm^3
Density=0.889g/cm^3

6. Emerson says:

The milky group have an average of .910 g/cm^3, which matches perfectly with the Delta block name.

7. S Skinner HC6 says:

1.14 g/cm^3 average for clear

• R McCoy HC6 says:

so we’re done?
thanks sydney

• R McCoy HC6 says:

should we do uncertainty?

8. M Cox says:

Moriah, ask her if we need to keep the sheets

9. H Watson HC6 says:

I can do the average for the paper white blocks?

10. A Stine HC6 says:

gray

11. Emerson says:

I’m guessing white is Alpha?

12. R Rivers HC6 says:

Short White block
Mass-38.58g
Length-8.80cm
Width-4.20cm
Height-1.90cm
V=l x w x h
V=8.80cm x 4.20cm x 1.90cm
V=70.2cm^3
D=m/V
D=38.5g/70.2cm^3
D=0.548g/cm^3
Mass – 38.5g

1) mannings block:
m=79.09g (electric balance)
(l=7.60cm; w=8.25cm; h=1.30cm—ruler)
V=lwh
V= 81.51cm^3
D=m/V
D=0.97g/cm^3

2) olivias block:
m=82.70g (electric balance)
(L=11.22cm; w=5.90cm; h=1.25cm—ruler)
V=lwh
V=82.75cm^3
D=m/V
D= 1.00g/cm^3

3) Jackson’s block:
m=65.96g (electric balance)
(l=12.20cm;w=4.15cm; h=1.30cm—ruler)
V=lwh
V=65.82cm^3
D=m/V
D=1.00g/cm3

Average: 0.97g/cm^3 + 1.00g/cm^3 + 1.00g/cm^3 = 2.97g/cm^3
2.97g/cm^3/3 = 0.99g/cm^3

Manning, Jackson Reeves, and I think that the average of the density of our block (0.99 g/cm^3) is closest to the density of Beta (0.967g/cm^3).

has anybody averaged the gray block

32. K Reynolds C4 says:

This week I finished the coin mass lab. I struggled with it at first because I couldn’t balance the ruler, but I eventually got it to balance and finished my project. I give myself a 4.

33. Moriah Tims says:

This week I was able to stay on top of homework assignments by using kahoots, quizlets, and class group chats in order to fully take advantage of the tools and resources that are open to me. This is so I can be better prepared for class and future tests. Based on this reflection, I give myself a 3 out of 5 because there are still things I could have done better.

34. E Dye HC6 says:

I would give myself four stars for this week. I was pleased, but frustrated, with my test this week. I was pleased with the grade, but I was mad at my careless mistake that led to me not getting the better grade. Additionally, I was pleased at the class’ ability during the Lab of Unknowns to communicate and calculate without speaking. Next test I will use my time more wisely, so that I could help eliminate careless errors.

35. HC6 M Cox says:

For this week, I would rate myself 3/5 stars. This week I stayed on top of my work, but was still a little lazy for most of the week. This was mostly due to the three day weekend. I did, however, run further than I ever have in my life, which is something I guess.

36. H Watson HC6 says:

This week has been three out of five stars for me. While I may have not gotten the grade I wanted to on my test. I know that I did the best of my ability. From this I have learned for the future a better way to study and take a test.

37. O Court HC6 says:

I would give myself three out of five stars for this week. I was happy with the way I worked hard to study and finish all my assignments while also having after school activities. I didn’t do as good as I wanted to on certain tests/quizzes, but I learned how to better prepare for them in the future by studying a different way. Next time I will try other studying methods as well as focusing on my work!

38. A Stine HC6 says:

This week, I would rate myself a 4/5. I did very well on my test, but looking at my mistakes, most of them were careless. I was frustrated at how I could’ve scored higher but was proud of myself for getting an A on the first test.

39. S Skinner HC6 says:

This week I rate myself four out five. I was happy with my grade on the test, but I could have done better if I didn’t make careless mistakes. I was also happy with how well the class worked together on the ID of Unknowns lab.

40. E Harrell HC6 says:

This week I’d rate myself a 4/5. I was happy with the way i studied for the test but I made careless mistakes on the test that held me back from getting a much better grade on the test. I think one solution for this could be to practice with time management, as time was the reason I wasn’t able to go back and check over my work and answers like I do on most tests.
