In an exothermic reaction the difference between the chemical energy of the reactants and the chemical energy of the products equals?
The amount of heat given off by the reaction
In the reaction of Al and FeCl3 to form Fe and Al2O3 energy is given off The reaction is classified as what kind of reaction?
exothermic reaction! (sudenly?)
What happens in a exothermic reaction?
In an exothermic reaction, the total making and breaking of bonds results in a net release of energy.
What is a chemical reaction in which more energy is taken in than given off?
Exothermic Reaction
What is the name given to the reaction where oxygen is removed from a chemical?
This reaction can be called "deoxidation" or "reduction".
A change of state where energy is given off is called an?
Exothermic reaction.
A change of state where energy is given off is called a?
Exothermic reaction.
A change of state where energy is given off it is called?
an Exothermic reaction
The amount of energy needed to start a chemical reaction is called what?
The energy required is called the activation energy. The minimum amount of energy needed to start a chemical reaction is given by the formula Ea=-RT*ln(k/A). R is the universal gas constant, T is temperature in Kelvin, k is the reaction rate coefficient and A is the frequency factor.
How much energy is given off in the reaction?
The energy is dependent on the reactants.
The energy and particles given off during a nuclear reaction are called?
Radiation
What is the minimum amount of energy needed to start a chemical reaction is called?
The energy required is called the activation energy. The minimum amount of energy needed to start a chemical reaction is given by the formula Ea=-RT*ln(k/A). R is the universal gas constant, T is temperature in Kelvin, k is the reaction rate coefficient and A is the frequency factor.
Energy is the energy needed to start a chemical reaction?
The energy needed to statr a chemical reaction is the 'Activation Energy' , which is given the symbol (Ea).
Is the energy given off in a fusion reaction greater or less than the energy off in a fission reaction?
greater than
What kinds of energy is given off in a chemical reaction?
nuclear
What word is used to describe a reaction in which energy is given out?
exothermic
How is the thermal energy different from temperature?
Thermal energy is energy given off by a substance due to a reaction.
