Acid-Base & Redox
What does pH stand for?
The potential of hydrogen ions
Three phosphate groups
Solid, liquid, gas
Is lighting a match exothermic or endothermic?
Exothermic
How long does it take for the earth to go around the sun?
365 days
A Neutralisation reaction
What is the full equation for aerobic respiration?
Glucose + oxygen -> carbon dioxide + water + energy
(C6H12O6 + 6 O2 -> 6 CO2 + 6 H2O)
How do the particles move in solid, liquid, and gas states?
Solid: vibrate in fixed position
Liquid: slide over each other, some movement
Gas: far apart and move randomly at high speeds
Fill in the blanks:
Endothermic reactions ___ heat, so the outside temperature decreases. Exothermic reactions ___ heat so outside temperature increases.
Endothermic reactions absorb heat, so the outside temperature decreases. Exothermic reactions release heat so outside temperature increases.
Name 8 elements on the periodic table
lol
What is the difference between an acid and a base?
An acid has a pH less than 7 and donates a proton (hydrogen ion). A base has a pH greater than 7 and accepts a proton.
Name TWO of the four reactions involved in aerobic respiration
Any two of the following:
Glycolysis, link reaction, krebs cycle, electron transport chain
Name THREE of the six factors effecting density
Any three of the following:
Mass, volume, temperature, state, altitude, and pressure
Name TWO of the four factors that increase the rate of chemical reactions
Any two of the following:
Temperature, pressure, catalyst, surface area
How many bones are in the human body?
206
Oxidation is when atoms ... electrons?
Explain how the relationship between ATP and ADP.
ATP can be interconverted to ADP. When the covalent bond between phosphate groups is broken, it releases energy, and forms ADP. A phosphate group can be added when it absorbs energy to reform ATP.
Define viscosity.
A substance's resistance to flow.
Mihir wants to make a SUPER big mentos-coke explosion. He is currently using normal-sized mentos. If he wants a bigger reaction, should he increase or decrease the size of the mentos?
He should decrease the size of the mentos to increase the surface area. Chopping the mentos up into a powder would significantly increase the rate of reaction!
Carbon dioxide + water -> glucose + oxygen
Define a reducing agent AND oxidising agent.
A reducing agent causes other substances to gain electrons.
An oxidising agent causes other substances to lose electrons.
In the cytoplasm, glycolysis converts glucose into what THREE products?
What's the difference between a Newtonian fluid and non-Newtonain fluid?
Newtonian fluids have a constant viscosity -- like water, oil, and alcohol.
Non-newtonian fluids don’t have a constant viscosity --like gel glue, emulsions, suspensions
What are the TWO conditions the reactants of a chemical reaction must meet to form products?
1. Collide with correct geometry
2. Have sufficient energy
How many Instagram follower's does Mihir and Sianna have COMBINED... times 5? (We will accept answers plus/minus 500).
Mihir (286) + Sianna (1,822) = 2,108
2,108 * 5 = 10,540!!
