Just as the babe trusts life when it gropes for its mother's breast, so the most skeptical of scientists trusts it when he declares that water is made of two parts hydrogen and one part oxygen, and sets it down for a certainty that this will always be so that he is not being played with by some sportive demon, who will today cause H2O to behave like water, and tomorrow like benzine.
The production of acetic acid from alcohol is a simple oxidation. The equation C2H6O + O2 = C2H4O2 + H2O shows the chemical change that occurs. This oxidation can be brought about by purely chemical means. While alcohol will not readily unite with oxygen under common conditions, if the alcohol is allowed to pass over a bit of platinum sponge the union readily occurs and acetic acid results.
It is well to know that when a piece of potassium is thrown on water the change which takes place is expressed by the formula K + H2O = KHO + H. But it is better still to have a mental picture of the tiny atoms clasping each other, and mingling so as to make a new substance, and to feel how wonderful are the many changing forms of nature.
You cannot conceive H2O, which is the chemical form of water, without having humidity associated; for that is an inherent quality of water. The power of attraction has as its function attractive, or magnetic, qualities. We cannot separate attraction from that power. The power of repulsion has as its function repelling—sending off. You cannot separate the effect from the cause.
Some H2O for a gent fainted. Look at Bantam's flowers. Gemini. He's going to holler. The colleen bawn. My colleen bawn. O, cheese it! Shut his blurry Dutch oven with a firm hand. Had the winner today till I tipped him a dead cert. The ruffin cly the nab of Stephen Hand as give me the jady coppaleen. He strike a telegramboy paddock wire big bug Bass to the depot. Shove him a joey and grahamise.
Dayson asked in a low voice, leering pawkily, as though to indicate that he was a man who could be trusted to think of everything. "Will be to-morrow, I think," said Mr. Cannon. "Got that letter ready, Miss Lessways?" Hilda sprang into life. "Yes," she said, handing it diffidently. "But if you'd like me to do it again you see it's " "Plethora of H2O," Dayson put in, indulgent. "Oh no!" Mr.
Maggie, get the corkscrew into action and fill the glasses with the choicest vintage of H2O. A toast. Here's to Larry!" The dinner was simple: beef stewed with potatoes and carrots and onions, and pie, and real coffee. But it measured up to Hunt's boast: the chef of the Ritz, limited to so simple a menu, could indeed have done no better.
He was pale and unhealthy and miserable and fawning, and an assiduous borrower of sums ranging from twenty-five cents to a dollar. One dollar was his limit. He knew the extent of his credit as well as the Chemical National Bank knows the amount of H2O that collateral will show on analysis. When he sat on my table he held one hand with the other to keep both from shaking. Whiskey.
We have water enough in tanks to last us three months, or indefinitely if we should have to be careful, as we can automatically distill and purify all our waste water, recovering absolutely pure H2O. We have compressed air, also in tanks, but we need very little, as the air is constantly being purified. Also, we have oxygen-generating apparatus aboard, in case we should run short.
Water is the compound that in its various forms does most to change the earth upon which we live, and it is more necessary for the continuation of life than anything else except air. Pure water does not exist in nature, that is, we have never found a compound of the composition H2O. Water always contains other matter. The various salts are dissolved in it and it absorbs gases.
