Units, Units, Units	Chemical Bonding	Gases, Acids, and Radioactives	Solutions	Stoichiometry
100 Convert 154 cm to m 1.54 m	100 Draw the Bohr model of Aluminum Drawn on board	100 When temperature decreases, pressure... decreases	100 What is a unit of concentration? molarity; ppm; ppb; ppt; molality; % by mass; % by volume; g/mL	100 Balance the equation and identify the mol ratio of H2 to H2O: H2 + O2 -> H2O 2 H2 + O2 --> 2 H2O Mol ratio is 1:1 (2:2)
200 Convert 50.2 g/L to g/mL 0.0502 g/mL	200 Why are ionic compounds composed of a metal and a nonmetal, not two nonmetals? metals lose and nonmetals gain, forming ions	200 A radioactive compound, K-40, exists inside of your bananas. Is this dangeorus? Why or why not? No, because it is a very small amount of radiation.	200 How many moles are in 1 L of a 1 M solution? 1 mol	200 How many mol of NaCl are produced from 1.6 mol Cl2 reacting with excess Na? 3.2 mol
300 How many mol are in 4.69 g of powedered sulfur? 0.15 mol	300 Write the chemical formula of aluminum oxide and dicarbon tetrachloride Al2O3 & C2Cl4	300 A cleaning solution of muriatic acid was spilled at a restaurant. The restaurant has drain cleaner and baking soda, two bases, available as well as vinegar, an acid, and sanitizer solution, a slightly acidic solution. Which chemical should the restaurant mix with the spilled acid to clean it up and why? baking soda because you can add excess to make sure there are no dangerous chemicals remaining. Drain cleaner is also dangerous so do not want to use it.	300 what does salt (NaCl) do when it dissolves in water? i.e., how does it change? it separates into ions and disperses throughout the liquid	300 How many grams of water are produced in the neutralization reaction between 15g NaOH and excess HCl? 6,75 g
400 Why do we use the mol unit at all? allows us to convert between compounds in reactions	400 Balance the reaction between carbon tetrachloride and oxygen to produce CO2 and HOH CH4 + 2 O2 --> CO2 + 2 HOH	400 Name three positive uses of radioactive elements. nuclear power, medical uses, smoke detectors, manufacturing uses	400 What is the concentration of 4 g of HCl in 0.5 L of water? 0.22 M	400 How many grams of aluminum chloride are produced when 18.0 g of aluminum are reacted with an excess of hydrochloric acid (H2 is one of the products)? 89g
500 Find my graduated cylinder magnet. It is located at ... You did it!	500 Predict the products and balance the equation: Synthesis reaction of magnesium and oxygen 2 Mg + O2 --> 2 MgO	500 What is nuclear fission and how do we use it to help society? Splitting of atoms; nuclear power plants; create medical isotopes	500 You are making a cake that requires a minimum concentration of 4 M sugar solution as one of the ingredients. You create a 0.5 L solution of 5 M C6H12O6 (sugar) then place that solution in your fridge overnight. When you come back in the morning, there are 42.5 g of sugar crystallized onto the sides of the container. Is this new solution going to work for your cake? What is the new concentration? Yes, 4.5 M	500 3 Ag + 4 HNO3 --> 3 AgNO3 + NO + 2 H2O If 50 mol of Ag and 50 mol of HNO3 are placed in a beaker together, which one will be used up, stopping the reaction and which one will be left over? Ag will be left over, 3:4 ratio causes more HNO3 to be used than Ag for each reaction.
