3U Chemistry Unit 2

Unit 2: Chemical Reactions

QuestionAnswer
Precipitate an ionic solid that forms by the reaction between an aqueous cation and aqueous anion
Conservation of Mass explains why we balance equations: there should be the same number of atoms of each type of element on both sides of the equation
coefficient the number in front of a formula that shows the # of particles of that substance involved in the reaction
subscript the number or symbol placed below and to the right of an element or compound
synthesis reaction a nonmetal oxide reacts with water to form an acid
decomposition reaction metal hydroxides form metal oxides and water
AB --> A + B metal carbonates form metal oxides and carbon dioxide when heated
combustion reaction always involves oxygen as a reactant and produces heat/light
complete and incomplete combustion always produces carbon dioxide and water
incomplete combustion produces carbon dioxide and water AND soot and/or carbon monoxide
single displacement reaction requires you to rank the reactivity of metals or halogens in aqueous reactions
double displacement reaction Acid + carbonate-containing compound produces an ionic compound, water + CO2
double displacement reaction requires you to consult a solubility table to determine whether a precipitate was formed
double displacement reaction Sodium hydroxide + ammonium chloride produces sodium chloride + ammonium hydroxide (which further decomposes into water + ammonia gas)
neutralization reaction an acid and base combine to form a salt and water
dissociation what happens to an ionic solid when it dissolves in water...it separates into its component ions
dissolving is a physical change
Corrosives can damage or even destroy metal. They begin to cause damage as soon as they touch the skin, eyes, respiratory tract, digestive tract, or the metal.
low solubility the substance will not dissolve in water and will remain a solid
account for... create a reason or explanation for...
demonstrate Show proof or evidence for something. Explain or show how something works.
Carbonic acid decomposes into water and carbon dioxide
Ammonium hydroxide decomposes into water and ammonia gas
nonmetal oxides plus water form acid rain!

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
