Matter is made up of particles that are constantly moving. All particles have energy, but the energy varies depending on the temperature the sample of matter is in.
Answer: -
A. An uncontrolled nuclear chain reaction is most likely to multiply exponentially.
Explanation: -
An nuclear chain reaction produces neutrons. These neutrons then can start new nuclear fissions. In a controlled nuclear fission, the number of neutrons allowed to start new fission is controlled.
In an uncontrolled reaction, the neutrons start fission very fast. These also start new nuclear fission, releasing more neutrons.
Thus. An uncontrolled nuclear chain reaction is most likely to multiply exponentially.
Normally in a mine the ore thats extracteed is unpure and contains many impurities and so are usually compounds and so must be then processed to form pure elements
some elements can be extracted from a solution of its ions such as magnesium
hope that helps
<span>We need to calculate the equivalent amount in units of moles of ammonium ions from the mass units. For this we need the molar mass of the substances involved. We calculate as follows:
31.3 g </span>(NH4)2CO3 ( 1 mol (NH4)2CO3 / 96.09 g (NH4)2CO3) ( 2 mol NH4 / 1 mol (NH4)2CO3 ) = 0.65 mol <span>ammonium ions</span>
