AP Chemistry - Principles of Oxidation-Reduction Reactions

1

Consider the following reaction:

$Cu_{(s)}+2Ag^{+}{(aq)}\rightarrow Cu^{2+}{(aq)}+2Ag_{(s)}$

What is the oxidizing agent, and what is the reducing agent?

2

In the following reaction, which compound is being oxidized?

$3CuS+8HNO_3\rightarrow3CuSO_4+8NO_{(g)}+4H_2O$

3

Consider the following reaction:

$Zn_(_s_) + CuSO_4_(_a_q_) \to Cu_(_s_) + ZnSO_4_(_a_q_)$

Which of the following statements is true?

4

Which of the following reactions involves the transfer of electrons?

Oomycetes of the genus Phytophthora are capable of causing economic damage by destroying crops. The name Phytopthora from the Greek phyton = plant, and phthora = destruction literally means plant-destroyer. However, chemists may battle their destructive effects.

The compound named copper(II) carbonate can be used to destroy the plant-destroyer, and can be produced as shown in the following equation:

$CuSO_4_{(aq)} + Na_2CO_3_{(aq)} \rightarrow CuCO_3_{(s)} + Na_2SO_4_{(aq)}$
