HW - equations

AP Chemistry: 17EQ
Directions: Write a “proper” equation for each chemical reaction, using the guidelines established previously in
this course. Also, answer any questions that follow a given reaction. Here are some additional reaction
patterns you should recognize:
when hydrogen peroxide is exposed to light, water is one of the products
boron tri-something compounds undergo synthesis with things having an unshared e – pair
1. Magnesium pellets are placed in 1.0 M hypochlorous acid.
1Q. How does the strength of hypochlorous acid compare to that of chlorous acid?
2. Solid zinc carbonate is added to 1.0 M sulfuric acid.
3. Chlorine gas is bubbled into a solution of potassium bromide.
3Q. What is the oxidation number of chlorine before the reaction? After the reaction?
4. A solution of sodium hydroxide is added to a solution of lead(II) nitrate.
4Q. If 1.0 L volumes of 1.0 M solutions of sodium hydroxide and lead(II) nitrate are mixed, how many moles of product(s)
will be produced, assuming the reaction goes to completion?
5. Calcium hydroxide solution reacts with perchloric acid solution.
5Q. The above reaction is between a strong acid and a strong base. Write the chemical formulas for all of the strong acids
and all of the strong bases.
6. A sample of iron(III) oxide is reduced completely with solid carbon.
6Q. Why was it necessary to use the term “reduced completely” above?
7. A small piece of potassium is added to water.
8. Powdered rubidium oxide is stirred into cold, distilled water.
9. Solid cadmium sulfite is subjected to intense heat.
10. Hypobromous acid is reacted with concentrated cesium hydroxide solution.
11. Boron trifluoride gas is added to ammonia gas.
11Q. Identify what type of acid/base each reactant represents.
12. A solution of barium chloride is added drop by drop to a solution of sodium carbonate.
12Q. What happens to the pH of the sodium carbonate solution as the barium chloride is added to it?
13. A solution of hydrogen peroxide is exposed to strong sunlight.
14. Titanium (IV) nitrate and potassium dichromate solutions are mixed.
14Q. In the product above, what type(s) of bonds are present?
15. Liquid ethanol is ignited in air.
15Q. What are the name and formula of the functional group in ethanol?
