Making Compounds
This is a compound between a metal and a non-metal.
What is a ionic compound?
This is how you determine % yield given theoretical and actual yield.
What is theoretical/actual?
The charge of a calcium ion.
What is +2?
The value is 6.022*10^23 and allows you to convert from moles to number of atoms / molecules.
What is Avogadro's number?
This is what a balanced chemical equation gives you. (Think like converting one element to another.)
What is a molar ratio?
This is the name of the compound LiF.
What is lithium fluoride?
This is the reactant that runs out first during a reaction.
What is the limiting reactant?
These elements have ions of the same charge and therefore similar properties.
What are elements in the same column?
You should use this conversion factor to get from grams to kilograms.
What is 1 kilogram / 1000 grams?
This is the unit conversion to get from grams to moles and vice versa.
What is molar mass?
This is the chemical formula for Carbon Tetrahydride
This is the percent yield if your actual yield is 76.25 g and your theoretical yield is 87.64 g.
What is 87%?
Elements in this group do NOT react with others and are located on the far right of the periodic table.
What are noble gases?
This is how many moles are in 45.0 grams of Ca.
What is 1.12?
This is the molar ratio between potassium chlorate and oxygen gas when the following chemical equation is balanced. KClO3 --> KCl + O2
What is 2:3?
This is the chemical formula for Magnesium Chloride.
What is MgCl2?
This is the limiting reactant of the following chemical equation when you have 11.07 grams of methane and 10.02 grams of oxygen gas.
CH4 + 2O2 --> CO2 + 2H2O
What is oxygen gas?
Elements in this group often have varying charges and therefore require a roman numeral when naming the compounds.
What are transition metals?
This is how many cm3 of gold are in a sample of 1.02 moles. (The density of gold is 19.3 g/cm3)
What is 10.41 cm3?
This is the balanced form of the equation for the synthesis of sodium oxide from sodium metal and oxygen gas. (Remember oxygen is diatomic!)
What is 4Na + O2 --> 2Na2O?
This is the name of the compound Fe(OH)2
Iron (II) Hydroxide
This is your percent yield given the following balanced equation if 72.20 grams of silver nitrate is your limiting reactant, and your actual yield is 42.01 g of silver.
Cu + 2AgNO3 --> Cu(NO3)2 + 2Ag
What is 91.62%?
This is what the rows of the periodic table are called.
What is a period?
What is 1.48 kg?
CH4 reacts with O2 to create CO2 and H2O. 25.2 grams of CH4 creates this many grams of water. (Make sure to balance the equation!)
What is 56.6 grams?
