Evaluation: I complete the following:

• I followed all the instructions dictated

• I brought all my materials (lab coat)

• I had a good behavior during the lab

• I made successfully my experiment

• I worked in-group as asked

• I enjoyed working with a didactic activity

Conclusion questions:

- How is your prediction match up with you observation?

They were close but not accurate, were almost all right but I missed some ones and made a few mistakes while predicting the reactions.

- Why were sodium and calcium not tested with acid?

Because they would react explosively and vigorously , putting in danger our security while doing the lab.

- Predict a metal not tested here that would a. react vigorously b. not react with water or dilute hydrochloric acid

A. potassium is a metal that would react with water or dilute hydrochloric acid

B. silver is a metal that would not react with water or dilute hydrochloric acid

- Write word and symbol equation for the reactions

Zinc:

- Zinc does not react with water

- Zinc + hydrochloric acid —> zinc chloride + hydrogen

- Zn(s) + 2HCl(aq) —> ZnCl2(aq) + H2(g)

Sodium:

- sodium + water —> sodium hydroxide solution + hydrogen

- 4Na(s) + 4H2O(l) —> 4NaOH(aq) + 2H2(g)

- Sodium + dilute hydrochloric acid —> sodium chloride + hydrogen

- 2Na(s) + 2HCl(aq) —> 2NaCl(aq) + H2(g)

Calcium:

- Calcium + water —> calcium hydroxide + hydrogen

- Ca(s) + 2H2O(l) —> Ca(OH)2(aq) + H2(g)

- calcium + dilute hydrochloric acid —> calcium chloride + hydrogen

- Ca(s) + 2HCl(aq) —> CaCl2(aq) + H2(g)

Copper:

- Copper does not react with water.

- Copper does not react with hydrochloric acid

Lead:

- Lead does not react with water

- lead + hydrochloric acid —> lead chloride + hydrogen

- Pb(s) + 2HCl(aq) —> PbCl2(aq) + H2(g)

Iron:

- Iron does not react with water

- iron + hydrochloric acid —> iron chloride + hydrogen

- Fe(s) + 2HCl(aq) —> FeCl2(aq) + H2(g)

Magnesium:

- Magnesium + water —> magnesium hydroxide solution + hydrogen

- Mg(s) + 2H2O(l) —> Mg(OH)2(s) + H2(g)

- magnesium + hydrochloric acid —> magnesium chloride + hydrogen

- Mg(s) + 2HCl(aq) —> MgCl2(aq) + H2(g)
