Gases
Two important gases for life.
Carbon Dioxide and Oxygen.
Like charges _________ (attract or repel)
REPEL
Without this polyatomic compound, life would not exist.
What is water?
Which elements are unreactive?
The first half of the noble gases.
Where Ms. Rivers studied chemistry.
What is western university?
A simple hydrocarbon that comes from cows and causes a lot of problems environmentally.
Methane.
Would you find hydrogen bonds in an aqueous solution of HF?
YES
Give an example of a compound that is both molecular and ionic.
Any polyatomic ion.
The reactants in a combustion reaction.
Hydrocarbon (fuel) and oxygen.
The way Ms. Rivers handles her disappointment the class' poor chemistry test scores.
By making a study time vs. test scores graph.
What is the acronym for the 7 diatomic gases?
HOFBrINCl
These types of forces increase in strength as temperature decreases, generally.
What are intermolecular forces?
Alkali metals and alkaline earth metals form only these type of compounds.
What are ionic compounds?
Is dissolution a chemical reaction?
SOMETIMES!
The only part of an atom that Ms. Rivers thinks is interesting.
What is an electron?
This extremely common gas is considered to be inert, except under extreme conditions in the presence of oxygen, where it reacts to form a compound that can cause acid rain.
What is nitrogen?
When these types of forces break, we have a chemical reaction.
What are intramolecular forces?
Combustion's product is the reactant in carbon fixation. NAME THAT COMPOUND.
Carbon dioxide.
The type of reaction we typically observe with solutions and in many electrochemical cells.
Double displacement reactions.
What colour was the food colouring I used for the experiment in week 3?
True or false: Suppose you have two identical birthday balloons, with one filled with the gas helium and the other blown up by you. Assuming they’re both filled to the same amount, these balloons will have the same number of molecules.
TRUE! PV= nRT
Ideal gases do not exhibit these types of forces, but real gases do.
Intermolecular forces (vanderwaals specifically)
What is a binary compound? Give an example.
A two-element compound.
All organic chemical reactions (including literally every reaction that supports life) is this type of reaction.
What is a redox (oxidation-reduction) reaction?
Ms. River's favourite type of chemical reaction (hint- I used this as an example in every single unit EXCEPT the grade 11 solutions unit- and not for lack of trying, it just simply does not work for that unit.)
Combustion
