pHabulous Chem
A substance that donates a proton (H+).
What is an acid?
The substance being dissolved.
What is the solute?
The temperature scale required for gas law calculations.
What is Kelvin?
This states energy cannot be created or destroyed; only change form.
What is the First Law of Thermodynamics?
The energy stored in a substance.
What is ehthalpy?
A substance that turns one color in the presence of acids and another color in the presence of bases.
What is an indicator?
What you can do to increase solubility if a gas solute is not dissolving well in water.
What is increase pressure or decrease temperature?
The law starting pressure and volume are inversely related.
What is Boyle’s Law? p1V1=P2V2
Energy in motion.
What is kinetic energy?
The energy necessary to start a chemical reaction.
What is activation energy?
What is commonly produced in an acid-based neutralization reaction.
What is salt + water?
A process that absorbed heat.
What is endothermic process?
The law stating volume and temperature are directly proportional.
What is Charles’s Law? (V1/T1=V2T2)
The heat required to raise the temperature of 1 gram of a substance by 1 0C.
What is specific heat?
A measure of the disorder that exists in any system.
What is entropy?
A concentration unit that tells how many moles of a substance are in a liter of solution.
What is Molarity (M)?
The number of moles of solute per kilogram of solvent.
What is molality (m)?
The equation PV=nRT is known as this.
What is the Ideal Gas Law?
The equation q=mc=T is used to calculate this.
What is heat absorbed or released?
The entropy of the universe must always either increase or remain the same; it can never decrease.
What is the Second Law of Thermodynamics?
The process of slowly reacting a base of an unknown concentration with an acid of known concentration (or vice versa) until just enough acid has been added to react with all of the base.
What is titration?
Spreading salt on icy and snowy roads is an example of this.
What is freezing-point depression?
The law stating total pressure equals the sum of partial pressures.
What is Dalton’s Law of Partial Pressures?
The temperature at which vapor pressure equals atmospheric pressure.
What is the boiling point?
This equation determines whether a process is spontaneous by relating enthalpy, temperature, and entropy.
What is Gibbs free energy equation?
