The following data were collected during the temperature-volume laboratory activity using hot oil and capillary tubes:
Temperature (°C) Length of trapped air in the tube (cm)
- Convert the Temperatures to Kelvin (K)
- The temperature was changed by the chemist. Which axis would this be?
- Using graph paper, construct a graph using the Kelvin temp and the Length in cm (which is the volume). Use Zero for the lowest values.
- Determine the temperature in Kelvin and Celsius where the volume would be Zero.
Use the Periodic Table and a calculator to help you convert the following. Please show all work.
- Convert 685 torr to atm
- If a balloon with a volume of 10.5 L and pressure of 765 torr is pushed to the bottom of a pool with a pressure of 4 atm, what will be the new volume in L?
Welcome back and Happy New Year! Now is a time to reflect on the past and make some changes to improve for the new year. Please write the questions and answer the following in your notes.
- What worked well for you this past semester in this class?
- What 3 specific things (study more is not specific) could you do to improve in this class?
- List and describe 3 class rules.
- When are cell phones allowed to be used in this class?
On Separate Paper, Balance the Equations using the smallest numbers for coefficients. Turn in to In-Box when finished.
- __H2 + __Cl2 –> __HCl
- __Na + __F2 –> __NaF
- __CH4 + __O2 –> __CO2 + __H2O
- __CaBr2 + __FeCl3 –> __FeBr3 + __CaCl2
- __C3H7OH + __O2 –> __CO2 + __H2O
On a separate sheet of paper, complete showing all your work and turn in to the inbox. You will need a calculator and Periodic Table and can use your notes.
- A chemical compound has a mixture of 1 copper, 1 sulfur, 10 hydrogens and 9 oxygens. The formula for the compound is CuSO4•5H2O. Determine the molar mass for the compound.
- The percent of water in the compound for number 1 is 36.08%. Prove it!
Pick 3 metals and 3 nonmetals and do the following:
- Write the symbol of the atom and how many electrons it has
- Write the symbol of the ion and how many electrons it lost or gained
- Label the ion as a cation or anion
- Create 9 compounds with your 6 ions and write their formulas and their names.
Example: 1 metal = Barium and 1 nonmetal = Astatine
- Ba = 56 electrons and At = 85 electrons
- Ba2+ lost 2 electrons and At1- gained 1 electron
- Ba2+ is a cation and At1- is an anion
- formula = BaAt2 and the name is Barium Astatide
