What else can I help you with?
Why is a burning candel a chemical change and not a physical changes?
Burning is a chemical reaction with oxygen (oxidation).
What is the function of a spark in a reaction between oxygen and hydrogen gas?
The spark is the activation energy. It is the catalyst of the chemical reaction.
What is a chemical reaction that absorbs heat energy and stores it the chemical bonds of the product?
An example of a chemical reaction that absorbs heat energy and stores it in the chemical bonds of the product is photosynthesis, where carbon dioxide and water react in the presence of sunlight to produce glucose and oxygen. The energy from sunlight is absorbed during the reaction and stored in the bonds of glucose.
Is chemical energy potential energy?
Yes and no. Yes before the reaction, No after the reaction.There is potential chemical energy among constituent substances in an exothermic reaction - such as in Hydrogen and Oxygen. When the chemicals combine, the reaction liberates thermal energy that was stored as potential chemical energy before the reaction.During the chemical reaction, the potential energy is converted into thermal (and perhaps other forms, such as light) energy.After the chemical reaction, the thermal energy is disspiated, and the potential energy is gone.
A chemical reaction takes place in which magnesium combines with oxygen to form magnesium oxide. Which of the chemical equations matches the reaction above?
The balanced chemical equation for the reaction between magnesium and oxygen to form magnesium oxide is: 2Mg + O2 -> 2MgO.
What chemical changes oxygen into energy?
Oxygen is not changed into energy. However, energy may be released when it combines with a range of other chemical compounds and elements.
Why is a burning candel a chemical change and not a physical changes?
Burning is a chemical reaction with oxygen (oxidation).
What is the chemical change of the sun's energy into glucose and oxygen?
This chemical reaction is called photosynthesis.
How do oxygen produce energy when there no light?
Through oxidation. That is to say, a chemical reaction that involves oxygen.
Oxygen in the blood why?
The chemical energy needed to drive all the chemical processes of the human body is obtained by an oxidation reaction that requires oxygen.
Can oxygen be oxidized in a chemical reaction?
Yes, oxygen can be oxidized in a chemical reaction.
What energy can be converted to what energy when mercury oxide is heated please help fast?
Metallic mercury has chemical potential energy, since it can combine with oxygen in an exothermic reaction, therefore, by driving out the oxygen with heat, you are converting heat energy to chemical potential energy.
What provides the chemical potential energy in a candle?
The chemical potential energy in a candle comes from the combustion of the wax through a chemical reaction with oxygen in the air. This reaction releases heat and light energy, which is used as a source of energy for illumination and heating.
Would a reaction with oxygen be a chemical or physical property?
A reaction with oxygen would generally be considered a chemical property because it involves a change in the chemical composition of the substances involved. Physical properties, on the other hand, do not involve changes in chemical composition.
What is the function of a spark in a reaction between oxygen and hydrogen gas?
The spark is the activation energy. It is the catalyst of the chemical reaction.
What energy transformation in iron?
When iron rusts, a chemical reaction occurs where oxygen in the air combines with the iron. This reaction results in a release of heat energy, which is a transformation from chemical energy (stored in the iron) to thermal energy (heat).
How is fire a chemical energy?
Fire is a chemical reaction that involves the rapid oxidation of a material (such as wood or gas) with oxygen in the air. This process releases energy in the form of heat and light, making fire a form of chemical energy transformation.
