Question #1• What is the mass of 3.5 moles

of Cu(NO3)2?

Molar mass = 187.5

3.5 x 187.5 = 656.25

Question #2• What mass of NaF would be

made from 42.1 L of F2 gas at STP?

2Na + F2 2NaF

42.1L / 22.4 L x 2 mol NaF x 42g =

158g

Question #3• Balance this equation:__ NaCl +__Cu __CuCl2 +

__Na2_ NaCl +__Cu __CuCl2 + 2_Na

Question #4• What type of reaction is this?

2 NaCl + Cu CuCl2 + 2 Na

Single Replacement

Question #5• Using this balanced equation,

2 NaCl + Cu CuCl2 + 2 Na

If you had 50g of Cu and 25g of NaCl, which would be the limiting reactant?

• Convert massmolmol Na for each• The one which makes the least Na is the limiting

• 50g Cu makes 1.57 mol Na• 25g NaCl makes 0.43 mol Na• NaCl is limiting

Question #6• Use Collision Theory to explain WHY

heating up a reaction causes it to occur faster (2 reasons)

Particles move faster so…

•Hit more often and•Hit with more energy

Question #7CaCO3(s) + HCl(aq) CaCl2(aq) + H2O(l) + CO2(g)

What would happen to this graph if the CaCO3 was ground finely?

Question #8• Name this organic compound

using IUPAC rules

C – C – C = C – C

2-pentene

Question #9• 2-Butene + HBr →

2-Bromobutane

Question #10• Write a balanced chemical

equation for the reaction between aluminum and chlorine.

2 Al + 3 Cl2 2 AlCl3

Question #11• What would you see if you

added solid calcium carbonate to hydrochloric acid?

• Write the balanced equationBubblesCaCO3 + 2 HCl CaCl2 + H2CO3 H2O + CO2

Question #12• Name some general

properties of basesBitter tastingIn cleaners

pH > 7[H+] < 1 x 10-7

Feel slipperyFormulas end with OH or CO3

Pink in phenolphthaleinBlue/purple in U.I.

Question #13• Name this:• C – C – C – C – C – C – C = C

l l Cl C

7-chloro-5-methyl-1 octene

Question #14• Calculate the pH of a solution

with a [OH-] of 1.2 x 10-10

2 ways…1.[H+] = 1x 10-14/[OH-] = 8.3 x

10-5 Then, pH = -log[H+] = 4.1

2.pOH = -log[OH-] = 9.9 Then, pH = 14-pOH = 4.1

Question #15• Why are saturated fats more

unhealthy?

(1)They remain solid at room/body temp

(2)So… they build up in your body• Clogging arteries• Making blood platelets sticky• Increasing bad cholesterol

Good Luck!
