Question 1

How would you classify reaction Eq. 5-2? ( Eq 5-2 is calcium (s) +water (l) --> hydrogen (g) + calcium hydroxide (aq))

neutralization

oxidation-reduction

precipitation

disproportionation

Question 2

In Eq. 5-3, calcium hydroxide is classified as, (Eq. 5-3 is calcium hydroxide + hydochloric acid-->water +salt)

an acid.

a reductant.

an oxidant.

a base.

Question 3

Which is the correct balanced equation for Eq. 5-2?

2Ca(s) + 2H2O(l) ? H2(g) + 2CaOH(aq)

Ca(s) + H2O(l) ? H(g) + CaOH(aq)

Ca(s) + 2H2O(l) ? H2(g) + Ca(OH)2(aq)

Ca(s) + 2H2O(l) ? 2H(g) + Ca(OH)2(aq)

Question 4

Which is the correct balanced equation for Eq. 5-3?

Ca(OH)2(aq) + 2HCl(aq) ? 2H2O(l) + CaCl2(aq)

CaOH(aq) + HCl(aq) ? H2O(l) + CaCl(aq)

Ca(OH)2(aq) + 2HCl(aq) ? H3O+(l) + CaCl2(aq)

Ca(OH)2(aq) + HCl(aq) ? H2O(l) + CaCl2(aq)

Question 5

What is the stoichiometric relation between calcium hydroxide and hydrocloric acid in Eq. 5-3?

1:1

3:1

1:2

2:1

neutralization

oxidation-reduction

precipitation

disproportionation

Explanation / Answer

1) oxidation-reduction

2) a base

3) Ca(s) + 2H2O(l) ? H2(g) + Ca(OH)2(aq)

4) Ca(OH)2(aq) + 2HCl(aq) ? 2H2O(l) + CaCl2(aq)

5) 1:2
