6.022 x 1023
What is a synthesis reaction?
A + B -> AB
What do you call a group of flamingos?
Formula for Heat Capacity

1s2, 2s2, 2p6, 3s2, 3p5
What is the limiting reagent?
The substance that is totally consumed when the chemical reaction is complete, while other reactant remains
What is an exothermic reaction?
This type of reaction decreases enthalpy and releases energy to the surroundings
What is the fifth sign of the zodiac?
Leo
What are the signs for Enthalpy if it is a exothermic reactions?
Delta H is negative
What is a mixture of two substances that stay physically separate?
Heterogenous Mixture
What is Guy Lussacs Gas Law?
As pressure increases, temperature increases
What is the products of a complete combustion reaction?
CO2 + water
What was the most streamed song on Spotify in August 2024?
Guess featuring Billie Eilish" by Charli xcx
State Hess's Law
If a reaction is carried out in a series of steps the Delta H for the overall reaction will equal the sum of the enthalpy changes for the individual steps.
How would I seperate a mixture of Copper Sulfate and Sand?
- dissolve copper sulfate by adding water
- filter out sand
- evaporate water from salt
What is the Ideal Gas Law
PV = nRT
The minimum amount of energy that is required for a set of reactants to begin reacting?
Activation Energy
Before embarking on a solo career, Beyoncé was part of what R&B group?
Answer: Destiny's Child
Identify whether respiration and photosynthesis is exothermic or endothermic
photosynthesis - endothermic (absorbs thermal energy from the sun to begin reaction).
respiration - exothermic (releases energy)
What is a covalent bond?
A bond where valence electrons are shared between atoms.
Define a Polar and Non-Polar Substance
In simple terms, polar means oppositely charged, and non-polar means equally charged. This is based off the differences in electronegativity
E.g. Polar - Water
E.g. Non-Polar Carbon Dioxide
List 4 ways to increase the rate of a chemical reaction
increase SA, increase temp, increase pressure (decrease volume), add catalyst
This country is the world's leading producer of bananas.
What is India?
Entropy is to measure the randomness of activity in a system, on the other hand, enthalpy is the measurement of the overall amount of energy in the system.
