Given the following descriptions, write balanced chemcial reactions with states

of matter (s),(l),(g), or (aq):

14) Some people have high iron in their water. This causes rust stains to form in

their sinks and toilets. Several rust removing chemicals that you can buy

contain hydrochloric acid which reacts with the rust. Write a chemical

equation showing how hydrochloric acid reacts with rust (Fe 2 O 3 ) to form

iron(III) chloride and water.

15) Let’s say you wanted to make a little hydrogen as part of a project to

simulate the Hindenburg disaster. You know that when metals are combined

with acids, hydrogen, and an ionic compound are produced. What would

happen if you reacted the zinc from inside a new penny with the sulfuric acid

that is in your car battery.

16) Your in that creative mood again and want to make one of those silly fake

snow displays, the kind you have in water and shake so that the fake snow

falls inside. One way to make fake snow is to make a precipitate. If you

reacted calcium chloride solution with silver nitrate solutions, you would get

a double replacement reaction. Would a precipitate form? Write out the

chemical reaction below.
