Gas Laws

100

This gas law is represented by P₁xV₁=P₂xV₂

What is Boyle's law?

200

This gas law is represented by V₁/T₁=V_2/T₂

What is the Charles law?

300

This gas law is represented by P₁/T₁=P₂/T₂

What is the Gay-Lussac Law?

400

This gas law is represented by PV=nRT

What is the combined gas law?

500

The R in the ideal gas law stands for:______________

What is the universal gas constant?

pH Scale

100

This ranges from 0-14, with 0 being the most acidic and 14 being the most basic.

What is the pH Scale?

200

This half of the pH scale usually donates protons and contains most safe things to consume.

What are acids?

300

This side of the pH scale accepts protons and contains most cleaners.

What are Bases?

400

This is represented by ?=-log[H+].

What is the equation to find pH?

500

This is represented by ?=10^-pH.

What is the equation to calculate the concentration of hydrogen atoms?

Solutions

100

What is solvent? 

What is doing the dissolving. 

200

What is a solution?

What is a homogenous mixture

300

What are factors that affect solubility? 

What is Temperature, Time, Amount of solute, Amount of solvent, Mix factors for?

400

What is the molarity of a 500mL solution that contains 0.75mol?

M=1.5

500

A 3m solution that is 700mL is added to 1,900mL. What is the new molarity?

M2= 1.12

Stoichiometry

100

This is shown as the atomic mass.

What is used to represent molar mass?

200

This is the relationship between moles

(# of Mol A=# of Mol B)

What is stoichiometry?

300

This represents the number(#) of moles of a given element.

What does the number of coefficients stand for?

400

This is called "Theoretical Yield"

What is max product?

500

This is represented by the use of coefficients and the molar mass of A and using stoichiometry to get the # of coefficients of B and then using the molar mass to achieve the final goal.

What is the process of going between Gram A and Gram B?

Balancing Equations

100

This is adding coefficient(s) to one or both sides of the equation to make them equal.

What is balancing equations?

200

These are represented by the number proceeding the Atomic symbol of an element or compound.

What are coefficients?

300

These are known as Synthesis, Decomposition, Single Replacement, Double Replacement, and Combustion.

What are the 5 types of equations?

400

These are known as (a+b), (a-b), (a+bc=b+ac), (ab+cd=ad+bc), and (propellant+o₂=H₂O+CO₂)

What are the 5 examples of each equation?

500

These are a) start with metals, b) go to nonmetals, c)balance polynomials as a unit, and d)do Hydrogen and Oxygen last.

What are the 4 tips given by Mr. Siemens for Balancing Equations?
