What is the minimum amount of unstable atoms needed to produce an uncontrolled chain reaction is called?
The minimum amount of unstable atoms needed to produce an uncontrolled chain reaction is called critical mass.
Which is the best description of activation energy?
The amount of energy needed to start a chemical reaction. Source: Biology class
The amount of energy needed to cause a chemical reaction to occur is the?
The amount of energy necessary to cause a chemical reaction to occur is called activation energy.
What is the amount of fissionable material required to continue a reaction at a constant rate?
The amount of fissionable material required to sustain a nuclear reaction at a constant rate is determined by the material's critical mass. The critical mass is the minimum amount of fissionable material needed to sustain a chain reaction, and it varies depending on the material and the reactor design. By controlling factors such as neutron moderation and absorption, reactor operators can adjust the critical mass to maintain a steady reaction rate.
Energy needed to kick start a reaction is called what?
The energy needed to kick start a reaction is called activation energy. It is the minimum amount of energy required for a chemical reaction to occur. It is usually provided in the form of heat or light energy.
What is the minimum amount of material needed to sustain a nuclear reaction?
The minimum amount of material needed to sustain a nuclear reaction depends on the type of reaction. For example, in a nuclear fission reaction, a critical mass of fissile material is needed to sustain a chain reaction. In a fusion reaction, high temperatures and pressures are needed to overcome the electrostatic repulsion between nuclei.
The minimum amount of unstable atoms needed to produce an uncontrolled chain reaction is called?
The minimum amount of unstable atoms needed to produce an uncontrolled chain reaction is called?
What is the minimum amount of unstable atoms needed to produce an uncontrolled chain reaction is called?
The minimum amount of unstable atoms needed to produce an uncontrolled chain reaction is called critical mass.
What is required for a chain reaction to start?
For a chain reaction to start, there needs to be a sufficient amount of fissile material, such as uranium-235 or plutonium-239, present in a compact enough form to reach critical mass. Additionally, there must be a neutron source to initiate the reaction by introducing a neutron to the fissile material.
The minimum amount of energy needed to start a chemical reaction is called?
The activation energy.
What is the minimum amounth of energy required for a reaction occur?
The minimum amount of energy required for a reaction to occur is called the activation energy. This energy is needed to break the bonds in the reactant molecules and initiate the chemical reaction. Once the activation energy is overcome, the reaction can proceed on its own.

The minimum amount of energy needed to start any reaction?
The minimum amount of energy needed to start a reaction is called the activation energy. It is required to break the bonds in reactant molecules and initiate the process of forming new bonds in the products. This energy barrier must be overcome for a chemical reaction to occur.
What is the amount of radioactive material needed to sustain a chain reaction in order to provide useful energy?
The critical mass.
The amount of energy needed to cause a chemical reaction to occur is the?
The amount of energy necessary to cause a chemical reaction to occur is called activation energy.
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.
True or false activation energy is needed only by chemical reactions that release energy?
true activation energy is the minimum amount of energy needed to start a chemical reaction
