Module 12
What is Boyle's law
The pressure and volume of a gas can have an inverse relationship and mass are held constant
Is a sandwich a heterogeneous?
Yes.
What is the law of conservation of energy?
Energy can neither be created nor destroyed, only changed
What is an acid?
A solution that produces H+ ions in water
What is collision theory
It states that reacting particles must collide with one another
What is Charles' Law
The volume of a given mass of gas is directly proportional to its absolute temperature
If mentors were soluble, what would be insoluble?
Soda/pop/coke.
What is the definition of specific heat?
Amount of energy required to raise 1 gram of something by 1 degree Celsius
If a solution was basic, what would the pH have to be?
Above 7
What is equilibrium
A state of balance where opposing forces or actions cancel each other out
What is Gay-Lussac's Law
The pressure of a given mass of gas is directly proportional to its absolute temperature
What is the definition of Dilution?
The process of reducing the concentration of solute in a solution, typically by adding more solvent.
What is the equation to calculate heat?
q=mcDELTAt
What is the only substance that has a pH of 7?
Pure water
Who is Le chatelier
A French chemist and Metallurgist
What is the combined gas law
The ratio of the product of pressure and volume to absolute temperature of a gas is equal to a constant
What is the formula of Molarity?
M= moles of solute/litters of solution
What is activation energy?
Energy required to start a reaction
What is the difference between strong acids/bases and weak acids/bases?
Strong acids/bases fully ionize while weak acids/bases partially ionize
What happens when you increase concentration
It shifts the position away
What's the Conversion of Molar Volume
1 mol = 22.4 L
what is the percentage breakdown of Hydrogen (h) in propane (C3H4)?
10.1
What is the difference between endothermic and exothermic reactions?
Endothermic reactions absorb heat while exothermic reactions release heat
What are the products in a neutralization reaction
Water and a salt
What does double arrows mean in a equilibrium equation
It means that the reaction is reversible
