WHAT TERM DESCRIBES ENERGY THAT REQUIRES TO GET CHEMICAL REACTIONS STARTED?
Activation energy describes the energy that is required to get chemical reactions started.
How does an atom react at low temperatures?
Chemical reactions require what is known as an "activation energy" to get started; if the reaction is exothermic, it may produce enough energy that it becomes self-sustaining. At lower temperatures there is less energy available, and so atoms are less likely to engage in chemical reactions.
What is the amount of energy needed to get a chemical reaction started known as?
activation energy
What Activation energy play in a chemical reaction?
Activation energy tells you how much energy chemical reaction needs to start. Example paper wont suddenly start burning, but you need first to put some energy in paper, before that reaction starts.
How do you have fire on your hand without burning?
There are various ways that a fire can be started without using a flame. Many chemical reactions produce enough heat to start a fire. One example is the mixture popularly known as "negative x". This mixture, which consists of ammonium chloride, ammonium nitrate, and zinc powder, will burn when exposed to a drop of water.
Which term describes energy that is required to get chemical reactions started?
Activation energy describes the energy that is required to get chemical reactions started.

What is the role of energy in chemical reations?
All chemical reactions need a certain amount of activation energy to get started.
What are complex proteins that speed up chemical reactions by lowering the amount of energy needed to get the reaction started.?
enzymes
Why do chemical reactions change properties?
when something undergoes a chemical reaction, its properties may change. meaning the properties could be different than whhat they started off as.
Why are fusion reactions difficult to recreate in a scientific laboratory?
Because of the very very high temperature and pressure required to get them started.
How does an atom react at low temperatures?
Chemical reactions require what is known as an "activation energy" to get started; if the reaction is exothermic, it may produce enough energy that it becomes self-sustaining. At lower temperatures there is less energy available, and so atoms are less likely to engage in chemical reactions.
Is the same gas produced in different chemical reactions?
If what you get is the same, chemically, as what you started with, then no, it's not a chemical reaction (be careful to take side effects into account: a series of reactions can yield the same molecule you started with, but make changes in other molecules in the process). If it's not chemically identical, then even if the properties are similar, it IS a chemical reaction.
What are the Product of chemical change?
They are chemical substances which are different from those that you started with.
Why does exothermic reactions need activation energy?
so the reaction can get started
Which of these is a challenge related to nuclear fusion reactions?
It is technically challenging to create these reactions safely and efficiently.
How- does a battery produce electricity?
A battery produces energy by converting energy released during chemical reactions into electrical energy. The chemical reactions are usually Redox reactions( reduction and oxidation reactions).A typical consists of 2 half cells - one where Oxidation takes place, the other reduction.The exchange of electrons in the reactions is through an external circuit- that's where you get your electricity.A battery produces energy by converting energy released during chemical reactions into electrical energy.
