Balencing
HCl+K==>K2Cl+H

What is the Law of Conservation of Energy?
Energy can't be created or destroyed.
If pressure increases, what happens to volume?
Volume decreases.
How do molecules behave in water?
They pull towards each other.
What is the difference between an endothermic and exothermic reaction?
"Endo" is internal while "exo" is external.
Ca2+NaBr==>CaBr+Na2
1,2,2,1
Potential energy is the amount of energy that is possible, while kinetic energy is the energy itself.
What is pressure caused by?
Pressure is caused by molecules bouncing off of other objects/walls.
What is the weakest bond of the IMFs?
LPFs.
What is one of the harshest reaction types from the five we have learned?
Combustion reactions
C4H8+O2==>H2O+CO2
1,6,4,4
Define activation energy and how it relates to certain types of reactions.
Activation energy is the energy it takes to cause a reaction.
If you increase the pressure of 8mL of gas from 19atm to 10atm, what's the new volume of the gas?
80*(1/10)=8mL
What is an example of a covalent bond?
Water, carbon dioxide
What is the difference between a synthesis and decomposition reaction?
Synthesis adds elements together while decomposition splits them up.
C6H12O6+O2==>CO2+H2O
1,6,6,6
Is potential energy positive or negative and why?
If a gas is 37C and you decrease its volume from 20L to 7L, what is the new temperature of the gas?
37+273=310K
310*(20/7)=885.7K
What does LDF (the bond type) stand for?
London Dispersion Forces
What are the five main known reaction types that we have learned?
Combustion, double, single, synthesis, decomposition
Fe+H2SO4==>Fe2(SO4)3+H2
2,3,1,3
What is an example of potential energy turning kinetic?
Why do spike bottomed shoes prevent you from slipping on ice?
The shoes have smaller points of pressure, causing the shoes to dig into the ice easier and stay still.
From strongest to weakest, list the IMF bonds
Hydrogen bonding, dipole dipole, LDFs
Why is it called a "Combustion reaction"?
A Combustion reaction involves a reaction that mainly causes fire.
