Advanced Chemistry: Test #1 (Chemical Reactions)

Multiple Choice: Circle the letter to the left of the best response for the following question (3 pts.)

1. If an ionic compound XT reacts with element Z to form compound ZT and the element X, then Z:

a. must be a metal that is more active than X

b. must be a metal that is less active than X

c. must be a nonmetal that is more active than T

d. must be a nonmetal that is less active than T

e. more than one of the above could be true

2. An attempted reaction between sodium and water yields:

a. NaOH

b. H₂ + NaOH

c. Na₂O + H₂

d. NaH + O₂

e. no reaction

3. For each of the following pairs of potential reactants, determine whether or not a reaction will occur. If you determine that no reaction will occur for a given set of reactants, cross out any work done on that problem and write ‘N.R.’ on the product side. If a reaction does occur, write a balanced molecular equation, showing the physical state of each reactant and each product. IF MORE THAN ONE REACTION IS POSSIBLE, WRITE THE EQUATIONS FOR BOTH REACTIONS. (15 pts.)

a. mercury + oxygen

b. tin + nitrogen

c. silver + bromine

4. For each of the following pairs of potential reactants, determine whether or not a reaction will occur. If you determine that no reaction will occur for a given set of reactants, cross out all work done on that problem and write ‘N.R.’ on the product side. If a reaction does occur, write a balanced molecular equation, showing the physical state of each reactant and each product. If more than one reaction is possible, you only need to write an equation for one of them. (3 pts. each)

a. aqueous iron(II) nitrate + aqueous lead(IV) chloride

b. sulphuric acid + solid aluminum

c. solid tin + aqueous magnesium chloride

d. solid silver + hydrochloric acid

e. solid lead + water

f. aqueous silver nitrate + aqueous sodium sulphite

g. solid tin + liquid mercury

h. aqueous sodium hydroxide + aqueous hydrogen chloride

i. solid potassium + gaseous helium

j. solid calcium + gaseous nitrogen

k. aqueous copper(I) sulphate + aqueous calcium chloride

l. aqueous ammonium phosphate + aqueous iron(II) chloride

m. solid zinc + copper(I) nitrate

n. aqueous sodium iodide + liquid bromine

5. Write the balanced equation (including physical states) for: (3 pts. each)

a. the combustion of butane (C₄H₁₀)

b. the dissociation of lithium carbonate

c. the decomposition of lithium chlorate

d. the combustion of propanol (C₃H₇OH)

e. the decomposition of lithium carbonate

6. For each of the following pairs of potential reactants, determine whether or not a reaction will occur. If you determine that no reaction will occur for a given set of reactants, cross out all work done on that problem and write ‘N.R.’ on the product side. If a reaction does occur, write a net ionic equation, showing the physical state of each reactant and each product. If more than one reaction is possible, you only need to write an equation for one of the reactions. (3 pts. each)

a. aqueous iron(III) chloride + aqueous lead(II) nitrate

b. sulphuric acid + solid iron

c. solid magnesium + aqueous aluminum chloride

d. aqueous ammonium nitrate + aqueous sodium sulphite

e. aqueous lithium hydroxide + aqueous hydrogen chloride

f. aqueous copper(II) chloride + liquid bromine

g. aqueous ferric chloride + aqueous sodium hydroxide

h. aqueous potassium bromide + gaseous fluorine

i. aqueous rubidium sulphide + aqueous strontium bromide
