What reading level is The Chemistry of Creation Being a Sketch of the Chemical Phenomena of the Eart book?
To quickly assess the difficulty of the text, read a short excerpt:
This was taken advantage of by chemists. It was easy to select substances which seized upon oxygen with avidity, while the nitrogen was left wholly uninfluenced by their presence. These substances were of many kinds. To enumerate a few we find employed, sulphuret of potassium, phosphorus, lead turn- ings moistened, spongy platinum, and the gas hydrogen. When the first three of these sub- stances are exposed to air, they immediately begin to oxidate, that is, to absorb its oxygen, leaving all th...e nitrogen behind. The experiments with spongy platinum and hydrogen were differently conducted to those with the former substances.
RUDE ANALYSIS OF AIR.
205 That a definite idea may be formed of this singular process, by which we learn this im- portant part of the chemical constitution of the air, the method of conducting the expe- riment with the substance Phosphorus, may be shortly stated. A portion of air should be confined in a glass tube, over distilled water, in which a small piece of phosphorus, fixed to the end of a wire, should be placed.
