HW SHEET

Reflection and Goals.

HW REVIEW

Lab groups

•Check your answers with the key

•Give yourself a ½ point for every correct formula, and a ½ point for every correct name

•Give yourself a total (mentally)

NOW!

Go through and fill in the blanks with your new partner

RULES FOR MOLECULE NAMING

1. 1st Non-Metal normal 2. 2nd Non-Metal ends in –IDE Prefixes are used to show # of atomsMono – 1, Di – 2, Tri – 3, Tetra – 4, Penta – 5, Hexa– 6

Mono is NEVER used with the 1st Non-Metal

Ex: Carbon Dioxide = CO2, not monocarbon dioxide

PRACTICE!

Name it!

1. CF4

2. NO2

3. NO

Write the formula!

4. Dicarbon difluoride

5. Sulfur monoxide

6. Phorphorus pentafluoride

Check yourself…

1. Carbon tetrafluoride

2. Nitrogen dioxide (NOT MONONITROGEN!)

3. Nitrogen monoxide

…before you wreck yourself!

4. C2F2

5. SO

6. PF5

NAMING ACIDS Acids are compounds that give off H+ ions when dissolved in water

In high concentrations these ions can disrupt our cell membranes and “burn” us

Contains Phosphoric Acid H3PO4

ACID FORMULAS AND NAMING Formulas always start with a Hydrogen Two types of Acids: 1) Does not contain oxygen

Hydro ______ ic Acid

(Blank= name of anion) HBr

Hydrobromic Acid

ACID FORMULAS AND NAMING

Notice you still have to make sure the compound is neutral! Cross the charges to make subscripts when writing the formula!

H+ + S2- = H2S or Hydrosulfuric Acid

H+ and N3- = H3N or Hydronitric Acid

H+ and NO2- = HNO2

H+ and NO3- = HNO3

ACID FORMULAS AND NAMING Formulas always start with a Hydrogen 2) Does Contain Oxygen

H+ + a polyatomic ion Don’t use hydro– , change the ending of the polyatomic

ate becomes ic ite becomes ous

Ex: H+ + SO42- (sulfate) = H2SO4 ate ic Sulfuric Acid

I ATE BIG AND GOT SICK,H2SO4

ATE IC SULFURIC ACID

TAKE A BITE YOU LITTLE WOUSH2SO3

ITE OUS SULFUROUS ACID

NOW YOU TRY! Give the name:

HCl

HClO2

HClO3

Give formula:

Phosphoric acid

Hydrophosphoric Acid

Hydrochloric Acid

Chlorous Acid

Chloric Acid

H3PO4

H3P

NON-WRITTEN EXIT TASK
