isnent for Chemical Equations Part Ii Single Displacement Reactions and Electrochemistry You must read the next experiment and then answer these questions. 1) Define the following terms: (4 pts) a) reduction: Shemic reestn nd aainina elec b) oxidation: doad stekon invdves lamelechon c) activity series d) single displacement reaction: . 2) Consider the following reaction: (2 pts each) CuSo(aq)Zn(s)Cu(s)+Znso4(eq) a) What is the charge on the copper ion in Cuso,?1+ (cu b) what is the charge on the Cu(s) metal? (a) c) Did the copper ion lose electrons or gain electrons to become copper metal? ained euehvinExplanation / Answer
a) reduction- reduction is the gaining of electrons by atoms in chemical reaction
b) oxidation - oxidation is the loss of electrons by atoms in a chemical reaction
c) activity series - It is the rank of metals in decreasing order of ability to displace hydrogen gas from acids and water
d) Single Displacement Reaction - It is a type of chemical reaction where an element reacts with a compound and replaces another element of that compound.
2) a The charge of Cu in CusO4 is +2
b) The charge of Cu metal is 0
C) Cu gained electrons to become Cu metal.
