Equation Writing In-Class Work
Directions: For the statements below…
1. Write a balanced net ionic equation
2. Answer the question that follows
Please do all of your work on a separate sheet of paper.
1. Solutions of zinc sulfate and sodium phosphate are mixed. If a wire loop is dipped into the final
reaction mixture and placed in a flame, what color will the flame turn?
2. Small chunks of solid sodium are added to water. Describe a test to confirm the gaseous product
in your reaction.
3. Ethene gas is bubbled through liquid bromine. What is the general relationship between carbon
and hydrogen atoms in an alkene?
4. A solution of nitric acid is added to solid calcium carbonate. Give two gaseous compounds that
could result from a redox reaction involving nitric acid.
5. A solution containing the silver (I) ion is allowed to undergo a redox reaction with a solution
containing the iron(II) ion. If the resulting solution is filtered, would anything remain on the filter
paper? Explain.
6. Solid potassium chlorate is heated. Would the acid made from the chlorate ion be strong or weak?
Explain.
7. Solutions of sodium fluoride and dilute hydrochloric acid are mixed. Which particle is bigger, the
fluorine atom or the fluoride ion? Explain.
8. Excess sodium cyanide solution is added to a solution of silver nitrate. How many  and  bonds
exist within the bond between the C and N in the cyanide ion?
9. Solid calcium oxide is heated in the presence of sulfur trioxide gas. If calcium oxide is placed in
water, give a statement describing the pH of the solution.
