200

How do you find how much 1 atom or molecules weighs when given the molar mass

Divide the right molar mass by Avogadro's number

300

Determine the mass in grams of a single molecule of water (H₂O)

2.99×10⁻²³g

400

How do you always solve empirical formula problems if not giving the mass

Assume 100 grams

500

How do you calculate Mass Percent

Mass Percent of Element= (Molar Mass of Compound/Mass of Element in 1 Mole of Compound) ×100

Chp.7

100

What are the 4 steps for balancing equations

Put a 1 in front of the biggest molecule

Balance the rest of the equation base on that molecule

If there is a roadblock double the whole equation

Balance the smaller molecules last. 

200

300

Define the 3 types of equations  

Molecular- Showing the complete normal formula for each compound

Complete ionic- Showing all elements/compounds as they are in a solution or the breaking down of aqueous solutions

Net ionic- Only showing the precipitate and its parts. 

400

Which is a combustion reaction

B.C₆H₁₂O₆+6O₂→6CO₂+6H₂O

C.HCl+NaOH→NaCl+H₂O 

D. H₂SO₄+2NaOH→Na₂SO₄+2H₂O 

B.C₆H₁₂O₆+6O₂→6CO₂+6H₂O

500

What are the 4 classifications of reactions 

Synthesis(combination)= A+B->AB

Decomposition=AB->A+B

Single displacement= A+BC-> AC+B

Double displacement= AB+CD-> AC+BD

Chp.8

100

What is the solution map for chemical equations mass conversions

mass A -> mol A -> mol B -> mass B

200

What are the 3 type of yields and how do they work

Theoretical-the amount of product that can be made in a chemical equation base on the amount of the limiting reactant

Actual- the amount of product actually produced

Percent- (ty/ay)* 100%

300

CaCO₃→CaO+CO₂

If 50.0 g of CaCO₃is heated and the percent yield of CO₂ is 90.0%, what is the actual yield of CO₂ in grams?

19.78 g

How do you use enthalpy 

mass->moles->energy 

500

Fe₂O₃+3CO→2Fe+3CO₂

Calculate the percent yield
