Heating sugar results in caramelization and is a chemical reaction. A chemical reaction is the process in which one substance is altered and forms a new substance with differing properties. More »

Sugar dissolving in water is a physical change and not a chemical one. Chemical changes only occur when new substances form. Dissolving sugar in water does not cause a chemical reaction to take place. More »

Dextrinisation is a kind of browning that occurs when foods containing starch are cooked, or exposed to an alkali, acid or enzyme. Dextrinisation is a chemical change in the starch molecule caused by the break down of su... More »

When sugar is burned, chemical changes take place, depending on if the sugar is burned in a complete or an incomplete combustion reaction. During a complete combustion reaction, sugar is transformed into CO2 and H20. In ... More »

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 wit... More »

The enthalpy of formation is defined as the energy, in the form of heat, given off or absorbed during a chemical reaction under the most stable conditions for the reaction to occur from pure elements. The basic formula f... More »

The term "chemical reaction" refers to any process that changes a set of chemical substances to another. That is, the substances that are put into a chemical reaction are different, on a molecular level, from those that ... More »
