agar butt): Only glucose fermentation has occurred. Glucose was degraded first. Since this substrate is minimally present‚ the small amount of acid produced on the slant surface is oxidized rapidly. Peptones in the medium are used in production of alkali. In the butt the acid reaction is maintained because of reduced O2 tension and slower growth of the organism. b.

Man‚ Muir and Emerson: The Ideas of Holy Environmentalism Abstract: Muir and Emerson initiated the beginnings of highlighting transcendental beliefs and connecting the thoughts of God through nature. While each author seemingly employs differing approaches to establishing this idea of holy environmentalism‚ the themes and stylings remain largely coherent with one another through the belief in nature as the inventions of God and therefore a medium in which mankind is to gain knowledge.

mixture changes color). In simple acid-base titrations a pH indicator may be used‚ such as phenolphthalein‚ which becomes pink when a certain pH (about 8.2) is reached or exceeded. Another example is methyl orange‚ which is red in acids and yellow in alkali solutions. Not every titration requires an indicator. In some cases‚ either the reactants or the products are strongly colored and can serve as the "indicator". For example‚ a redox titration using potassium permanganate (pink/purple) as the titrant

that in moist air‚ it combines slowly with oxygen to form aluminum oxide. The aluminum oxide forms a very thin‚ whitish coating on the aluminum metal (N/A‚ n.d.). This element is also a fairly active metal. It reacts with many hot acids and with alkalis. Aluminum also reacts quickly with hot water‚ and in powdered form‚ it catches fire quickly when exposed to a flame (N/A‚ 1996-2012). Back then‚ the Ancient Greeks and Romans used alum as an astringent‚ for medicinal purposes‚ and as a mordant in

baking soda is added. These ingredients are cake raising agents which release carbon dioxide‚ allowing the cake to rise. Baking powder (a white powder) is a dry chemical ingredient used in the making of a cake. It consists of sodium bicarbonate (an alkali)‚ acid salt (such as tartaric acid) and starch that when exposed to water‚ react together to form carbon dioxide gas causing it to expand‚ thereby producing bubbles and allowing the cake dough to rise. Typically today‚ modern baking powders are double
