Quick bread leavening process, agents (one or more food-grade chemicals—usually a weak acid and a weak base) are added into the dough during mixing. These agents undergo a chemical reaction to produce carbon dioxide, which increases the baked good's volume and produces a porous structure and lighter texture. Yeast breads often take hours to rise, and the resulting baked good's texture can vary greatly based on external factors such as temperature and humidity. By contrast, breads made with chemical leavening agents are relatively uniform, reliable, and quick. Usually, the resulting baked good is softer and lighter than a traditional yeast bread. Chemical
Substance theory inverse relation is participation. Thus in the example above, just as red inheres in the apple, so the apple participates in red. Two common arguments supporting substance theory are the argument from grammar and the argument from conception. The argument from grammar uses traditional grammar to support substance theory. For example, the sentence "Snow is white" contains a grammatical subject "snow" and the predicate "is white", thereby asserting "snow is white". The argument holds that it makes no grammatical sense to speak of "whiteness" disembodied, without asserting that snow or something else "is" white. Meaningful assertions are formed by virtue
