What else can I help you with?
Do all chemical reaction require activation energy?
Yes, they do.
What is the relationship between the temperature and the rate of chemical?
Heat energy is necessary for some chemical reactions to occur. Some chemical reactions are endothermic meaning they require or absorb energy for a chemical reaction to occur. Other chemical reaction are exothermic meaning they release energy when the chemical reaction takes place..
Will a chemical reaction that asborbs energy happen with out a source of energy?
No, a chemical reaction that absorbs energy is called an endothermic reaction. The transfer of heat from the surrounds into the substance. In reactions, energy is always CONVERTED, not created which means that nothing can be converted i.e. heat to chemical if there is no heat or initial energy.
Which of the following is not required in a chemical reaction?
An enzyme is not required in a chemical reaction. While reactants, energy, and a chemical reaction pathway are essential components of a chemical reaction, enzymes can speed up the reaction but are not always necessary for it to occur.
What is an example of a chemical reaction that releases energy?
One example of a chemical reaction that releases energy is the combustion of methane gas (CH4) in the presence of oxygen. This reaction produces carbon dioxide (CO2) and water (H2O) along with a significant amount of heat and light energy.
Do all chemical reaction require activation energy?
Yes, they do.
Does a change in energy always occurr during a chemical reaction?
no

Is energy always given out when a chemical reaction takes place?
Yes.

What is an exothermic reaction?
An exothermic reaction is a chemical reaction that is done by the release of heat. It gives out energy to its surroundings. The energy needed for the reaction to occur is less than the total energy released.

Different chemical reactions take different amounts of what?
Energy. Different chemical reactions require different amounts of energy to occur, which can affect the speed and extent of the reaction.
A chemical reaction that absorbs free energy?
Endothermic reactions are chemical reactions that absorb free energy, typically in the form of heat. These reactions require an input of energy to proceed. Examples include photosynthesis and the melting of ice.
Do glow sticks require batteries?
No. They include their energy source, to glow for a while (thanks to a chemical reaction).
What is a chemical reaction in which energy is absobed?
Endothermic reaction is a type of chemical reaction that absorbs energy. Energy is a property of objects.
