The alcohol in "gasohol" burns according to the following equation: C2H60 + 3 O2 → 2 CO2 + 3H20.
In a test, 89.11 moles of water is collected from this reaction. How many moles of
alcohol (C2H60) had been consumed? (Hint: this is a two box problem.)
Only enter the number into the box. Do NOT write in any units.

Asample of silver (with work function ? = 4.52 ev) is exposed to an ultraviolet light source (? = 200 nm), which results in the ejection of photoelectrons. what changes will be observed if: silver is replaced with copper (? = 5.10 ev) more photoelectrons ejected no photoelectrons are emitted fewer photoelectrons ejected more energetic photoelectrons (on average) less energetic photoelectrons (on average)

Which term describes a fracture in the earth at which land stays in the same place? a. joint b. fault c. split d. hinge

The boiling point of propanoic acid is higher than that of 1-butanol because: propanoic acid has a higher molecular weight than 1-butanol. propanoic acid is more soluble in water than 1-butanol. propanoic acid is a better hydrogen bond donor than 1-butanol. propanoic acid forms hydrogen bonded dimers and 1-butanol does not. 1-butanol forms hydrogen bonded dimers and propanoic acid does not.
