A bit of help:
WA ch 8
Anything with the symbol 4.0 check means that you must report with accurate significant figures
3. The cube is not aluminium
7. Remember to report in the format 6.02e+23 instead of 6.02x10^23
WA ch 11
T-charts galore! Writing it down will solve a lot of problems.
3. Remember, 1 mol ZnCl2 = 2 mol Cl
10. 1 dozen = 12 things and 1 mol = _________ things
11. molar mass
19. Density = mass/volume
WA ch 15
Read the instructions!
5. Remember, % mass = g solute/g solution x 100. So set it up this way:
___ % = g NaCl / (g NaCl + ? g H2O) *100 Then solve for g H2O
6-9. Remember, Molarity = mol/liters
9. Don't forget to convert moles to grams
WA ch 12 + 11.4 & 11.5
FOLLOW the STEPS! It really does work.
Stoichiometry: 1) Balance equation
2) Convert grams (or beginning units) to moles
3) Convert moles to moles
4) Convert moles to grams (or needed units)
Ask your 3 questions:
1) Where do you I want to end up?
2) Where do I start?
3) How do I get there? Stoichiometry, equations, conversions, etc
Check your formulas, your units, be so careful!
4. Ni(CN) - add subscripts to this format
7. Na2CO3 = 37.03%
H2O = 62.97%
8. 1 CaSO4 . 2 H2O
name: calcium sulfate dihydrate
9. initial mass of hydrate = (mass of hydrate + crucible) - (mass of empty crucible)
mass of anhydrous solid = 8.57
1 BaCl2 . 2 H2O
barium chloride dihydrate
11-13. Rewrite the equation, reporting particles, then moles, then convert moles to grams
remember: molecules = covalently bonded; formula units = ionicly bonded
14-15. They want to know what step is that converts moles of one thing to moles of another thing
16. Divide each number by the smallest one to find the moles
17-18. mole-mole conversions
19-23. mole-mass and mass-mole conversions
24-30. mass-mass conversions
26. convert kg to g. Your answer will be in scientific notation
31-38. Limiting reactant
Remember to do 2 T-charts, compare the 2 answers you get
38-46. To find excess, 1) take the amount produced from the limiting reactant
2) convert the amount produced back to the excess reactant = amount excess used
3) initial amount - amount used = excess left over
39-45. Percent yield (theoretical yield from stoichiometry - limiting reactant)
44. BONUS! You can skip this one if you want - if you do it correctly, you get the bonus points!
47-50. Mixed principles - use what you know!
