Fission is a form of nuclear transmutation because the resulting fragments are different elements from the original atom. A neutron-induced fission of U-235 results to krypton and barium.

A uranium235 sample starts with 200 atoms and 700 million years later there are 100 atoms What is the halflife of uranium235?
700 milliion years. The definition of half-life is the period of time during which one-half of the atoms of an element undergo decay into other elements.
When energy is absorbed during a chemical reaction the reaction is classified as what reaction?
endothermic reaction
What is a heat reaction?
This the heat released during a chemical reaction.
What symbols are used to show what happens during a reaction?
It helps show you what goes on during a chemical reaction
What is a correct description of enthalpy of a reaction?
The enthalpy of a chemical reaction is the change of heat during this reaction.
What substances during chemical reactions are involved?
The initial substances in a chemical reaction are called reactants.
What is necessary sustain a nuclear chain reaction?
In a chain reaction, neutrons released during the splitting of an initial nucleus trigger a series of nuclear fissions.

The reactant are the new materials produce during a chemical reaction?
No. The reactants are the initial materials that undergo chemical reaction; the new materials produced have the unsurprising name "products".
Using ccor work on contaminated material when must you work in mopp 4?
during the initial phase
Is endothermic a chemical reaction?
Yes. A chemical reaction which absorbs heat during the reaction. The opposite to exothermic which releases heat during the reaction.
How do enzymes affect reactions?
The initial velocity of a gradually increases during enzyme substrate reaction. The concentration of the substrate also increases with it.
What is a reactant?
A reactant is a substance that participates in and changes during a reaction.
When energy is absorbed during a chemical reaction the reaction is classified as what reaction?
endothermic reaction
What is released during the light reaction?
Carbon dioxide is released during the light reaction.
What happens to the potential energy of the molecules in a reaction?
The potential energy of the molecules change during a reaction.
Is energy absorbed or released during a decomposition reaction?
Energy is released during a decomposition reaction.
