Calculate the amount of heat (in kJ) required to raise the temperature of 250 grams of water
from 30°C to 90°C. (The specific heat of water
is 4.18 J/g.°C.)
Answer in units of kJ.

Draw two cyclic constitutional isomers of cis-1

The arrangement of particles is most ordered in a sample of

Chlorine and water react to form hydrogen chloride and oxygen, like this: 2cl2 (g) + 2h2o (g) → 4hcl (g) + o2 (g) also, a chemist finds that at a certain temperature the equilibrium mixture of chlorine, water, hydrogen chloride, and oxygen has the following composition: compound concentration at equilibrium cl2 0.55m h2o 0.57m hcl 0.53m o2 0.34m calculate the value of the equilibrium constant kc for this reaction. round your answer to 2 significant digits.
