Answer:

27°C

Explanation:

q = 1500 J

m = 50g

c = 4.18 J/g°C

q = m·c·ΔT

ΔT = \frac{1500J}{50g*4.18\frac{J}{gC} } = 7C

ΔT = final temperature - initial temperature

Final temp = 20 + 7 = 27°C

kari74 [83]
Use the PV = nRT equation T is in Kelvins = 31 + 273 = 304 K

P(0.5) = (2.91)(0.0821)(304)
P(0.5) = 72.6289
P = 145.25 atm or 1.45x10^2 atm

The main difference is in the presence of a carbon atom; organic compounds will contain a carbon atom (and often a hydrogen atom, to form hydrocarbons), while almost all inorganic compounds do not contain either of those two atoms.
