Biology - Chemistry of Life Review

TermDefinition
Intramolecular Forces -Non-Polar Covalent bond -Polar Covalent bond -Ionic bond
Range of Electronegativity of Non-Polar Covalent bond 0 - 0.4
Range of Electronegativity of Polar Covalent bond 0.4 - 2
Range of Electronegativity of Ionic bond 2+
What is a Non-Polar Covalent bond? Anything bonding to itself, plus any C-H bond and CO2
What is a Polar Covalent bond? Nonmetals kind of close on Periodic Table
What is an Ionic bond? Far away from each other on Periodic Table, big elcecrtonegativity difference
Intermolecular Forces -Dipole-dipole (Hydrogen bonds) -London Dispersion Forces -Vander Waals
Hydrogen Bonding Bonding to F, O, N intermolecularly
Electronegativity Trend Diagonal up to right top of the Periodic Table
Strong Intermolecular Force -Solid, possibly liquid -High melting point + boiling point -Low vapor pressure
Weak Intermolecular Force -Gases -Low melting point + boiling point -High Vapor Pressure
What is it when reactant + heat 🡢 product? Endothermic reaction, heat is absorbed
What is it when reactant 🡢 product + heat? Exothermic reaction, heat is released
Intramolecular Force 🡢 Intermolecular Force Non-Polar Covalent 🡢 ? Polar Covalent 🡢 ? Ionic 🡢 ? Intramolecular Force 🡢 Intermolecular Force ? 🡢 London Dispersion Force ? 🡢 Dipole-Dipole (Hydrogen Bonding) ? 🡢 None
7 Strong Acids 1. HCl 2. HBr 3. HI 4. H2SO4 5. HNO3 6. HClO3 7. HClO4
What do the 7 strong acids do in a solution? They fully dissasociate/split
What is a buffer? A solution that resists change in pH when a OH- and H+ are added
What is a Conjugate base? Is the species that remains after an acid donates a proton (H+) during a chemical reaction. (Formed when acid loses proton)

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
