What else can I help you with?
What energy is the energy needed to start a reaction?
Activation Energy.
What type of energy does a glow stick use?
A glow stick uses chemical energy to produce light. This is typically achieved through a chemical reaction between hydrogen peroxide and a phenyl oxalate ester, which produces a chemiluminescent reaction that gives off light.
In what form is the energy released in this reaction?
In an exothermic reaction heat energy is released.
What statements about activation energy is correct?
Activation energy is the minimum amount of energy required for a chemical reaction to occur. An increase in activation energy leads to a decrease in reaction rate. Catalysts lower the activation energy required for a reaction to proceed, increasing the reaction rate. Activation energy does not affect the overall energy change of a reaction, only the speed at which it occurs.
What does the energy hill represent of an energy diagram?
The energy hill on an energy diagram represents the activation energy required for a chemical reaction to occur. It shows the energy difference between the reactants and the transition state of the reaction. The height of the energy hill determines the rate at which the reaction will proceed.
What term is used for the type of chemical reaction that gives out heat energy?
Exothermic reaction gives free heat (energy).
What term is used 4 the type of chemical reaction that gives out heat energy?
Exothermic reaction gives free heat (energy).
What reaction gives out energy?
If by energy you mean heat energy exothermic reactions.
When a chemical reaction takes in more energy than it gives off it becomes what?
When a chemical reaction takes in more energy than it gives off, it becomes an endothermic reaction. In an endothermic reaction, energy is absorbed from the surroundings in the form of heat.
exothermic?
A reaction that gives off energy
This is a reaction that gives out energy?
This type of reaction is known as an exothermic reaction. In this process, energy is released in the form of heat to the surroundings. Example of an exothermic reaction is the combustion of fuel.
What is the name of a chemical reaction that gives out energy?
A chemical reaction that produces energy is said to be exothermic. In comparison, if it consumes energy it is endothermic.
Is it true that Every chemical reaction gives off energy?
yes it does <><><> No- some reactions ABSORB energy. In terms of heat energy, some are exothermic, and some are endothermic.
What reaction gives out heat and other kinds of energy?
Endothermic
What is a reaction that gives out a lot of heat?
An example of a reaction that gives out a lot of heat is the combustion of gasoline in engines. This reaction releases a large amount of energy in the form of heat and light.
Which type of reaction gives off heat?
An exothermic reaction gives off heat as a result of energy being released in the form of heat. In an exothermic reaction, the products have lower energy than the reactants, leading to the release of heat to the surroundings.
What is the name of the exothermic reaction that gives off co2?
alternative energy
