is limiting the reaction and which will be
left over ("excess")
Announcements: All last work is due today if you
want it to be counted for the 6 wks.
Get rockets done this weekend!
Warm-up: 72 grams of magnesium nitrate is
produced from the action of a sodium nitrate
solution on crystalline magnesium hydroxide.
What mass of sodium nitrate had to be used?
How many molecules of sodium nitrate is that?
Steps in the process...
- Write correct formulae
- Balance the Equation
- Molar masses of all substances involved
- Given grams --> moles (use mm)
- moles given --> moles wanted (use ideal ratio)
- moles --> grams
and/or - moles --> molecules/atoms/ions/...
40g Al(NO3)3 + 24g Mg
