Draw a representation that shows the interactions between solute and solvent in an aqueous solution of potassium bromide. Ball and stick models are fine.
Must show ion-dipole interactions
In America, what sport do people watch every weekend during the fall months?
Use Coulomb's Law to explain why BaSO4 is not soluble in water but MgSO4 is soluble in water
The ion dipole forces between Mg+2 and water are greater than the ion-dipole forces between water and Ba+2. This is because Mg has a smaller radius, which is explained through Coulomb's law.
What famous story about a headless horseman and a nervous school teacher is set during the autumn season?
The Legend of Sleepy Hollow
Fractional distillation was used to isolate an unknown volatile substance that had contaminated the well at a rural property. Is the boiling point of the unknown substance greater than, less than, or equal to 100 degrees C at 1 atm?
Less than, because the vapor pressure of the unknown substance when it is in liquid phase must be greater than that of water an any given temperature in order for it to be isolated through fractional distillation. As a substance boils when its vapor pressure equals the atmospheric pressure, the boiling point must be less than 100 degrees C at 1 atm.
What was the first group in history to use scarecrows?
Explain why potassium bromide dissolves in water
Ion-dipole
Why do leaves change color in the fall?
Less chlorophyll production due to less exposure to sunlight.
Explain how solutes can be separated by paper chromatography.
The solvent is either attracted to the polar cellulose paper or the non polar solvent, and travels far as such.
Which country started the tradition of pumpkin carving?
Ireland
What is the Halloween themed town where the infamous Witchcraft Trials of 1692 took place?
Salem, Massachusetts
What animal is most associated with Halloween and said to bring bad luck if it crosses your path?
Black cat
Explain why a glass of soda at 30 degrees C will go flat faster than a glass of soda at 5 degrees C.
The solubility of gas decreases as the temperature of the liquid solution increases. Higher kinetic energy means the particles break free from the intermolecular forces holding them.
When is Día de los Muertos celebrated? (think the movie Coco)
November 1 and 2
A fractional distillation was used to isolate an unknown volatile substance that had contaminated the well water of a rural property. What can be said about the relative strengths of intermolecular interactions among and between the components in question?
What Green Day song from their 2004 album has become synonymous with the beginning of fall and the passage of time?
Wake Me Up When September Ends
Explain why NO is more soluble in water than O2.
NO is larger than O2, and the NO bond is slightly polar allowing for more dipole-dipole interactions when it dissolves in water.
What iconic TV series is set in the fictional town of Stars Hollow and often features fall festivals and celebrations?
Gilmore Girls
Explain why bubbles of CO2 form when you open a bottle of soda.
When the lid is removed, equilibrium shifts because the pressure is released, allowing bubbles to form.
The iconic "basic girl" drink of the pumpkin spice latte is composed of which 5 spices?
Cinnamon, nutmeg, clove, allspice and ginger.
Which explorer is credited with introducing pumpkins to Europe in the 15th century?
Christopher Columbus
What movie is based on a true story about the son of a coal miner that goes on to become a NASA engineer?
October Sky
What is the name of the fictional town where “Stranger Things” is set, which experiences eerie occurrences during fall?
Hawkins Indiana
Fall equals football and this movie, based on a true story, follows a football team at a newly integrated high school. What movie is it?
Remember the Titans
What type of tree produces acorns?
Oak
