Moles
We need to do this when going from grams to moles.
What is divide by molar mass?
The formula below models this type of reaction:
A + B --> AB
What is a Synthesis Reaction?
This is how many Sig Figs 4.2000 kg has.
What is 5 sig figs?
This is the unit for percent composition.
What is Percent?
This is the reactant that runs out first.
What is the limiting reactant?
This is the molar mass for oxygen (O).
What is 16 g/mol?
The formula below models this type of reaction:
Ax + By --> Ay + Bx
What is a Double Replacement Reaction?
We attain mole ratios from this.
What is a balanced chemical equation
This is missing from the following equation:
%comp = .../(Mass of Compound)
What is the mass of the element?
This is the equation for percent yield.
What is
% Yield = (Actual)/(Theoretical)
This is the molar mass for NaCl.
What is 58.44 g/mol?
This type of bond would form from the reaction of Mg and Cl?
What is Ionic bond?
This is scientific notation for the following number: 64,000,000.
What is 6.4 x 107?
This is the percent of hydrogen in the following compound: H2O.
What is 11%?
This is the limiting reactant for the following reaction. We start with 2 mol H2 and 2 mol O2.
2H2 +O2 --> 2H2O
What is H2?
There are this many grams in 9.7 moles of NaCl.
What is 566.9 g?
This type of bond would form from the reaction of P and F.
What is Covalent?
This is the opposite of melting.
What is freezing?
This is the percent of C in the following compound: CH4.
What is 75%?
In a chemical reaction, we get 14.8 g from the reaction. We calculated that the reaction should yielded 25.7 g. This is percent yield of the reaction.
What is 57.6%?
% Yield = (14.8)/(25.7) * 100%
A container holds 32.0 grams of Methane (CH4). There are this many molecules of Methane present in the container.
What is 1.2x1024. (12x1023)
This is the chemical name for CuO.
What is Copper (II) Oxide?
The melting point of a substance is the same as this property of substance.
What is the freezing point?
This is the percent of Mg in the following compound: Mg(NO3)2.
What is 16%?
A student is performing a synthesis reaction to create Sodium Chloride (NaCl). The student starts the reaction with 1.0 mole of Sodium (Na) and an unlimited supply of Chlorine gas (Cl2). After the reaction is complete, the student weighs the product and finds an actual yield of 48.0 g. This would be the percent yield of the reaction.
2Na + Cl2 --> 2NaCl
(Theoretical: 58 g) What is 82.8%?
