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
A substance that undergoes a change in a chemical reaction is called a reactant or reagent. Usually, chemical reactions comprise of the changes that only pertain to the movement of electrons in the forming and breaking of chemical bonds.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 >
Burning a match is a chemical reaction because the reactant, primarily wood, is chemically altered into a different substance, ash. A chemical reaction or change involves one or more reactants having bonds broken or altered to form new substances. In the case of burning a match, wood and oxygen are transformed into ash and smoke, two distinctly new products.Full Answer >
The chemical reaction between aluminum and bromine is an exothermic one that produces aluminum bromide. The equation of the chemical reaction is 2 Al + 3 Br2 ? 2 AlBr3. It indicates that two molecules of aluminum combine with three molecules of bromine to produce two molecules of aluminum bromide.Full Answer >
