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.
Where is the mass to a chemical reaction found?
A hemical reaction has no mass; only chemical compounds have molar mass.
What is true about the balance of mass in a fusion reaction?
In a fusion reaction the mass of the products is less than the mass of the reactants.
In an ordinary chemical reaction the mass of the product you?
In an ordinary chemical reaction, the mass of the products is equal to the mass of the reactants. Matter is conserved.
Can mass go down in a chemical reaction?
The mass of reactants is equal to the mass of products.
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 the density of a block of wood with a mass of 120g and a volume of 200cm3 power?
Density = Mass/VOlume = 120g/200cm3 = 0.6 grams per cm3
In a nuclear reaction mass must be a lost to produce energy?
The mass is not lost but transformed in energy.
When an acid and a base produce a salt and a water what is the reaction?
sodium chloride
In a nuclear reaction mass must be lost to produce energy. true or false?
False. Both mass and energy are conserved.
What is required for a chain reaction to start?
Critical Mass is that minimum amount of fissionable material needed to maintain a chain reaction
What is the amount of fissionable material that must be present in order for a nuclear reaction to take place called?
The critical mass. With an amount of U-235 or Pu-239, the smallest critical mass will be a sphere. For a nuclear reactor, it will be the minimum number of fuel assemblies loaded to produce a chain reaction.
The size of the force needed to produce acceleration of an object is determined by the objects what?
Mass ?
What is the density of an object with a mass of 120g and a volume of 7ml?
Density = Mass/Volume = 120 grams/7 ml = 17.142857... grams per ml.
What force would be needed to produce an acceleration of 1 ms-2 on a ball of mass 1kg?
One Newton would be needed.
How many cups are there in 120g of dog food?
mass can't be converted into volume! silly! what's the density of the dog food? 120g of light fluffy dog food will take up more volume that heavy dense dog food
What is the amount of radioactive material needed to sustain a chain reaction in order to provide useful energy?
The critical mass.
