Calculate the ΔH for the following reaction: Cu + ½ O2 CuO
Given the following information:
CuO + Cu Cu2O ΔH = -11 kJ
2 CuO Cu2O + ½ O2 ΔH = +115 kJ

a  solution  is always transparent, light passes through with no scattering from solute particles which are molecule in size. the  solution  is homogeneous and does not settle out. a colloid is intermediate between asolution  and a  suspension. while asuspension  will separate out a colloid will not.

the answer to your question is c

i don't see a text, but i am gonna assume this *orbit* the curved path, usually elliptical, described by a planet, satellite, spaceship, etc., around a celestial body, as the sun.
