Q:

What are the advantages and disadvantages of chemical energy?

A:

Quick Answer

The advantages and disadvantages of chemical energy depend on the ways in which energy is stored and released during a chemical reaction. Chemical energy is the force that powers everything in the world, from the human body to vehicles on the road.

Full Answer

According to Health Research Funding, chemical energy is defined as the energy stored within chemical bonds released through exothermic reactions. There are several energy sources that can be used to create a chemical reaction. These range from crude oil, coal, wood and other combustible material. One of the main advantages of using chemical energy is that it is the most abundant source of energy available. Chemical energy is also easily combustible, which makes it great for powering engines and vehicles.

The main disadvantage of chemical energy is that it has adverse effects on the environment. Burnt crude oil emits carbon dioxide into the atmosphere, which contributes to global warming. Chemical energy is also harmful to human health due to the pollution released as a byproduct of the chemical reactions. It is for this reason that scientists are looking for renewable energy sources that are more efficient and less harmful than chemical energy. Current alternatives to chemical energy include solar energy and wind energy.

  • Q:

    How can a chemical reaction be shown to be endothermic?

    A:

    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.

    What is the chemical reaction for burning sugar?

    A:

    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.
