The reaction between baking powder and an acid is an example of an everyday chemical reaction. As bread bakes, the reaction releases carbon dioxide, which is then trapped in the structure of the cooked dough to make it light and fluffy.Know More
Another example of an everyday chemical reaction is the digestion of food in the stomach. In this case, the acid in the stomach reacts with the proteins, fats and other molecules contained within the food and breaks them down into more manageable parts. Some of these molecules are bonded and dispersed throughout the body via the blood stream, while others go to the intestines where they are fermented by bacteria. Fermentation consists of a series of chemical reactions.
There are two main types of fermentation: lactic acid fermentation and ethanol fermentation. The names refer to the end product, but they both start with the same reactant, glucose. Bacteria consume the glucose and form the by-product. Lactic acid fermentation can also start with lactose, which is found in milk, and is used to create yogurt. This sugar is then broken down in the presence of water to form glucose, another everyday chemical reaction. The bacteria utilize the glucose, excreting lactic acid.Learn more about Chemistry
One of the biggest chemical reactions made from household items is between ammonia and bleach, creating toxic gas that can cause asphyxia and black-outs. Chemical reactions occur when two unlike molecules are joined.Full Answer >
Energy can play many different roles in chemical reactions, and it can be a product of a chemical reaction, a necessary component for a chemical reaction, or energy can have little part in a chemical reaction. Chemical reactions that require additional energy are called endothermic reactions, while those that produce energy are called exothermic reactions.Full Answer >
A chemical reaction can be shown to be endothermic if it absorbs heat and causes a decrease in the temperature of its surroundings. Illustrative lab experiments performed in schools to demonstrate endothermic reactions often use the reaction occurring between vinegar and baking soda or the reaction between barium hydroxide and ammonium nitrate. The latter reaction, if taking place in a flask resting in a small amount of water, will absorb enough heat from the water to cause it to freeze.Full Answer >
The chemical reaction for the burning of sugar by the body is shown through the chemical equation C12H22O11(s) + 12 O2(g) -----> 12 CO2(g) + 11 H2O(l). In this equation, C12H22O11 is the sugar, which burns by reacting with the oxygen to create carbon dioxide and water.Full Answer >
