Convert the following description of a chemical reaction toan equation.

1.       Combustion ofalcohol: alcohol (C₂H₆O_(l))is burned in the presence of oxygen. Carbon dioxide and water are produced.

2.      Iron oxide is formed from Iron and oxygen gas.

3.      Plants use water and carbon dioxide to make glucose(C₆H₁₂O₆)and oxygen.

Draw the following chemical reaction.

4.       CH_4(g)+ 2O_2(g)→ 2H₂O_(g)+ CO_2(g)

Describe this reaction in words.

5.      CH_4(g)+ 2O_2(g)→ 2H₂O_(g)+ CO_2(g)

6.      2H₂O_(l)+ electricity → 2H_2(g)+ O_2(g)

Tuesday, February 12th and Thursday, September 14th Start a new heading in your notebook. Title it“Chemical Reactions with Metals.”

Instructions: For this lab wewill be mixing 9 substances and looking for chemical reactions. Copy down the above table. Leave space in each numbered cell.

Once the table is copied down, predict if the reactions 1-15will occur or not. If the reaction willhappen, write down the balanced reaction. And explain why it will happen.  If the reaction will not happen, write downwhy it will not.

1.       Cu + Zn → Noreaction. Copper and zinc are both metals. They will not combine through asynthesis reaction because they can’t form a covalent compound or an ioniccompound.

2.      Cu + NaCl → Noreaction. Copper will not replace sodiumin a single displacement reaction because sodium is higher on the activityseries than copper.

Tuesday, February 19th and Wednesday, September 20th Start a new heading in your notebook. Title it“Double Displacement Reactions.”

Announcements Quiz 7: Chemical Reactions will be on the 25^thand 26^th. 

Complete and balance thefollowing chemical reactions. Name thetype of reaction as well.

1.       C₂H₆+ O₂ →

2.       H₂+Cl₂→

3.       HgO (heat)→

4.       Zn(II)SO₄+Al →

5.       H₂SO₄+ CaO→

Write down the 3 outcomesthat will cause a double displacement reaction to happen.

3.

Last class period we looked at reactions 1-15 from thetable. We only found 2 singledisplacement reactions.

Now, let’s do the same for 16-36. If a reaction will happen, it will be adouble displacement.

Let’s assume we perform these reactions in test tubes.

How many NaCl(aq) test tubes will we need? ___

How many CaOH(aq) test tubes will we need? ___

How many Cu(II)SO4(aq) test tubes will we need? ___

How many HCl(aq) test tubes will we need? ___

How many NaOH(aq) test tubes will we need? ___

How many CaCl2(aq) test tubes will we need? ___

How many KCl (aq) test tubes will we need? ___

How many total test tubes will we need?____

 If the reaction willhappen, write down the balanced reaction. And explain why it will happen.  If the reaction will not happen, write downwhy it will not.

Do this for the remaining reactions (16-36)

16.   NaCl(aq) +CaOH(aq) → No reaction. 
   CaCl₂is soluble, and so is NaOH. So double displacement reaction will happen.
