* Pb +2 charge, O -2 charge * cancel out 

400

Potassium Dichromate 

K₂CrO₄

K has +1 charge, CrO₄ - 2 charge 

500

Ionic Vs. Covalent Bonding

100

Ionic Bonds are made up of ______ and _______

metal and non-metals 

200

Covalent bonds are between ___________ 

non-metals 

* Covalent- cousins 

300

What Type or reaction is Li₂O? 

Ionic

Li: metal 

O: non-metal 

400

CO₂  Is what type of reaction? 

Covalent

Both non metals 

500

True of False: When you form bonds you must always bond to the coupled lone pairs. 

False!!! Don't break up couples. You bond only to the single standing electrons. 

Relationships

100

Using PV=nRT 

What type of relationship does Pressure and Volume have? 

 Inverse

* Remember SI! Same side= Inverse relationship. 

200

Using PV=nRT

What is the relationship between pressure and Temperature? 

Direct 

*OD- Opposite = direct relationship. 

* The more you add to a container the hotter it will get. 

300

Speed of light= (frequency) (wavelength) 

What is the relationship between frequency and wavelength? 

Inverse! 

* SI= Same side- inverse 

400

Energy=(Planck's constant) (frequency)

What is the relationship between energy and frequency? 

Direct 

* OD= Opposite- direct

500

A fixed mass of gas at 300K and 1 atm has a volume of 100mL. Which change doubles the volume of gas? 

a. Increasing temperature to 600k 

b. Reducing temperature to 150K 

A. 600k 

PV=nRT volume and temperature are directly proportional. If you double temperature 300K to 600K volume will do the same. 

Conversions

100

How many L are in 350 mL ? 

.350L 

* you divide by 1,000, or move the decimal three times to the right. 

200

What process do you use to convert mmHg to atm? 

Divide by 760 mmHg 

1 atm= 760 mmHg

300

How do you convert kJ to J? 

multiply by 1, 000 

1 kJ= 1,000 Joules 

400

1 mole (any element) = 

Molar mass of element/ Use periodic table. 

500

1 mole of (any element) = how many particles or atoms? 

6.022x10²³

(Avogradro's number)
