Calculate the heat capacity of a wood block if you know that 1500.0 g of the wood loses 6.75x10^4 joules of energy and causes its temperature to decrease
from 57°C to 32°C.

Nitrogen dioxide decomposes according to the reaction 2 no2(g) ⇌ 2 no(g) + o2(g) where kp = 4.48 × 10−13 at a certain temperature. if 0.70 atm of no2 is added to a container and allowed to come to equilibrium, what are the equilibrium partial pressures of no(g) and o2(g)
