How many grams of methane gas (ch4) need to be combusted to produce 11.8 l water vapor at 1.85 atm and 304 k? show all of the work used to solve this problem.
ch4 (g) + 2o2 (g)yields co2 (g) + 2h2o (g)
use pv=nrt
r = 0.0821 l atm/mol k

How many moles are equivalent to 55.5g of nano3

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.

Imagine that you push on a large rock. at what point does your effort change the rock’s mechanical energy?
