Fission equation of u-235 dating, choose a video to embed
Perhaps you meant fusion instead, if so it is: You can do this by changing the amount of any of the reactants or products, but you cannot change the chemical formulae of the chemicals. We want 10 oxygen atoms rather than 2, so we multiply the amount of O 2 molecules by 5. Nuclear weapons[ edit ] The Little Boy gun type atomic bomb dropped on Hiroshima on August 6, was made of highly enriched uranium with a large tamper.
What is a balance equation? This means we need to multiple the amount of H 2 O on the right by 4. This should preferrably be an element that is present in only one reactant and one product to make things simpler.
When you balance an equation you write out the reactants and products and then add molecules of either reactants, products, or both to make sure the number of molecules of each element going into the reaction is equal to the number coming out.
Why do equations have to be balanced? Our equation is now balanced and looks like this: So far the equation looks like this: Then, change the amount of one of the chemicals to make the number of atoms of that element the same on each side.
If at least one neutron from uranium fission strikes another nucleus and causes it to fission, then the chain reaction will continue. If the reaction will sustain itself, it is said to be criticaland the mass of U required to produce the critical condition is said to be a critical mass.
There is not a balancing equation.
Because of the law of conservation of mass, the reactants have the same mass as the products. In nuclear reactorsthe reaction is slowed down by the addition of control rods which are made of elements such as boroncadmiumand hafnium which can absorb a large number of neutrons.
Most modern nuclear weapon designs use plutonium as the fissile component of the primary stage,   however HEU is often used in the secondary stage.
The Law of Conservation of Mass states that mass is neither created or destroyed in an ordinary chemical reaction.
That is basically what it is, I am a chemistry teacher and I recommend you check out the website http:
