Concentration
These units are used to express molarity.
What are moles per liter (mol/L or M)?
The net ionic equation for the following complete ionic equation:
Ca2+(aq) + 2Cl-(aq) + 2Na+(aq) + 2OH-(aq) ---> Ca(OH)2 (s) + 2Na+(aq) + 2Cl-(aq)
What is Ca2+(aq) + 2OH-(aq) ---> Ca(OH)2 (s) ?
The name for the reactants left over after a reaction is complete.
What are excess reactants?
The following combination of reactants can be described as this type of reaction.
Ca(NO3)2 (aq) + NaOH (aq) --> ? + ?
What is a double replacement reaction?
This process can be described as "making a solution weaker"
What is dilution?
The ions in solution that remain unchanged throughout a reaction.
What are spectator ions?
When balancing a chemical equation, these numbers can be changed in order to make sure the reaction follows the Law of Conservation of Mass.
What are coefficients?
These reactions are easily identified by the presence of oxygen gas as a reactant.
What is combustion?
Aqueous solutions are classified as these types of mixtures which are known to be "uniform throughout"
What are homogenous mixtures?
The word used to describe an ionic compound's ability to dissociate in water.
What is soluble/solubility?
This many moles of hydrogen gas are required to produce 12 moles of H2O in excess O2 according to the balanced chemical equation:
2 H2 (g) + O2 (g) --> 2 H2O (g)
What are 12 moles of H2?
This is used to determine whether or not a metal will be replaced in a reaction.
What is the activity series?
These substances are described as the ones "in greatest abundance" within a solution.
What are solvents?
The ions from this group on the periodic table are generally considered always soluble in water, regardless of anion.
Considering the unbalanced equation, this compound would be the limiting reactant for a reaction involving 15 moles of solid calcium and 12 moles of aluminum bromide solution.
Ca (s) + AlBr3 (aq) --> CaBr2 (aq) + Al (s)
What is solid calcium?
What are decomposition reactions?
A solution that is made of 116.88 grams of sodium chloride, NaCl, and is dissolved in 4 L of solution is determined to have this molarity.
What is 0.5M NaCl?
This precipitate forms from the combination of sodium chloride and silver (i) fluoride. (For full points you must determine the chemical formula of the precipitate, not just the name)
This mass, in grams, of CO (molar mass 28.01 g/mol) is needed to react completely with 150 g of Fe2O3 (molar mass: 159.69 g/mol) according to the unbalanced equation:
Fe2O3 (s) + CO (g) → Fe (s) + CO2 (g)
What is 78.93 grams of CO?
The formation of this product is evidence of an acid/base neutralization reaction.
What is liquid water, H2O?
