Writing Chemical Reactions
The following reaction would result in these two products:
CH4 + 2O2 -------> ? + ?
What are carbon dioxide and water?
Classify the following reaction:
2H2O → 2H2 + O2
Decomposition
The insoluble product in a precipitation reaction is called this
what is the precipitate?
Matt breaks into his dad's chemical cabinet and decides to throw some quick lime into water which gets hot! Matt knows a chemical reaction occured because of this
These are present during a reaction, but don't participate in the formation of the product.
What is a spectator ion?
State the law of conservation of matter
Matter cannot be created nor destroyed, only transformed
Classify the following reaction:
Zn + 2HCl → H2 + ZnCl2
Single displacement
What is the correct formula for magnesium (IV) nitrate?
Mg(NO3)2
food coloring is added to water - did a chemical reaction occur?
What is no - the combination is a mixture.
What are solvents?
How would you balance the following equation:
CH4 + Cl2---------->CCl4 + HCl
CH4 + 4Cl2---------->CCl4 + 4HCl
Classify the following reaction:
HCl + NaOH → NaCl + H2O
Double displacement
Using a solubility table, will lead carbonate form a precipitate?
Yes
What is gas formation?
This is a solution of known molarity (i.e. concentration)
What is a standard solution?
before a chemical reaction can be properly balanced, the reactants and products must be this (meaning they are the correct formula)
what is electrically neutral or balanced?
CaO + H2O -----> Ca(OH)2 represents this type of chemical reaction
What is synthesis?
What are the products formed when Sodium Hydroxide and Magnesium Chloride are reacted?
Magnesium hydroxide and Sodium chloride
Two clear solutions are mixed and immediately the solution becomes cloudy white. We know a reaction occured due to this
What is the formation of a solid?
This is the thing that gets dissolved
what is a solute?
What is a salt?
True or false: precipitation reactions can be classified as double displacement reactions?
True
Barium chloride solution and calcium nitrate solution are mixed. Will a precipitate form? If so name the precipitate
Magnesium metal is ignited over a bunsen burner. How do we know that a chemical reaction occured?
What is the release of energy in the form of light?
Precipitation reactions are only possible because of the unique property of water
What is water is polar?
