suvedi (bs26733) – H02: Stoichiometry – mccord – (51600) 1 This print-out should have 29 questions. Multiple-choice questions may continue on the next column or page – find all choices before answering. This assignment comes from Chapters 2 and 3 in your book. Nomenclature (the nam- ing of compounds, etc...) is in Chapter 2. Chapter 3 is on stoichiometry. You need to know how to calculate all the types of prob- lems on this homework. ALEKS does do this well. READ Chapter 3 and LOOK at the ex- amples. This is important although I will not formally cover it in class. You are expected to know this already. 001 10.0points Which compound has the wrong chemical for- mula? 1. Mg(OH) 2 2. (NH 4 ) 2 SO 4 3. CaOH 4. Ba 3 (PO 4 ) 2 002 10.0points Cobalt(III) oxide would be the label for 1. Co 3 O. 2. CoO 3 . 3. CoO. 4. Co 2 O 3 . 5. Co 3 O 2 . 003 10.0points Give the formula for aluminum hydroxide. 1. AlH 3 2. Al(OH) 3 3. AlOH 3 4. AlOH 004 10.0points Choose the formula for the compound potas- sium dichromate. 1. K 2 Cr 3 2. K 2 Cr 3. K 2 CrO 4 4. K 2 Cr 2 O 7 5. KCrO 3 6. KCr 2 O 7 7. KCrO 4 8. K 2 Cr 3 O 4 005 10.0points How many atoms are in 0 . 0427 mol K? Answer in units of atoms. 006 10.0points Which one has the greatest number of atoms? 1. 3.05 moles of helium 2. 3.05 moles of argon 3. All have the same number of atoms 4. 3.05 moles of water 5. 3.05 moles of CH 4 007 10.0points Each mole of Al(NO 3 ) 3 contains how many moles of oxygen atoms?
