Average Atomic Mass: H.W

Follow the link below and after watching the video provided answer questions 2 and 3 found below the video.

https://www.ck12.org/c/chemistry/calculating-atomic-mass/lesson/Calculating-Atomic-Mass-CHEM/?referrer=featured_content

Calculate the following Average atomic mass remember to show your work:

  1. Neon has two major isotopes, Neon-20 and Neon-22. Out of every 250 neon atoms, 225 will be Neon-20 (19.992 g/mol), and 25 will be Neon-22 (21.991 g/mol). What is the average atomic mass of Neon?
  2. In a sample of 200 Chlorine atoms, it is found that 151 are Cl-35 (34.969 amu), and 49 are Cl-37 (36.966 amu). What is the average atomic mass of Chlorine?
  3. Without doing any math, are there more Bromine-79 atoms or more Bromine-80 atoms on earth? (Hint: look at the periodic table.)

October Project

Using the following concepts each group will create an images only presentation. Each image will be utilized to explain each concept and answer questions in class. Keep in mind that for several concepts you can use only one image.

  • Frame of reference
  • Displacement
  • Positive displacement
  • Negative displacement
  • Velocity
  • Speed
  • Average velocity
  • Instantaneous velocity
  • Slope
  • Rise
  • Run
  • Acceleration

Velocity vs Time Graphs: H.W.

Make a graph for the following and calculate the slope for each graphed trajectory.

  1. A car goes from rest to 25 m in 10 s.
  2. A car starts at 30 m and reaches 45 m after 5 s.

Using the table below graph the following trajectories, calculate the velocity and label each one of them:

Displacement 1:  From the 3rd position to the 5th position.

Displacement 2: From rest to 0.4 s and back to rest ( calculating that the second displacement took the same amount of time)

Displacement 3: From 0.6 s to 1 s

October Mini Project

Group 1: Dwarf planets and ewatereventfeature20150407_mainxo planets.

Group 2: Meteors, Meteoroids, and meteorites.

Group 3:  Comets

Group 4: Asteroids.

Each group will bring a presentation that explains what each concept is, its structure/composition and where its found in or out of our solar system. Each group will also provide a brief fictional story that illustrates the properties of their assigned interstellar body as a fictional character.
