Fission is the energetic splitting of large atoms such as Uranium or Plutonium into two smaller atoms, called fission products. To split an atom, you have to hit it with a neutron.
Hope this helped.
Answer:
Rubidium belong to Alkaline group 1, and
Strontium belong to Alkaline group 2.
Explanation:
We know that elements are organized on the periodic table based on their properties. The statement correctly predicting and explaining the chemical reactivity of two metals is given below -Rubidium (Rb) is more reactive than strontium (Sr) because strontium atoms must lose more electrons.
Answer:
(a) When aqueous solution of hydrochloric and ammonia chemically react together then it results in the formation of ammonium chloride.
The reaction equation for this reaction is as follows.
Now, ioni equation for this reaction is as follows.
Cancelling the spectator ions, the net ionic reaction equation is as follows.
(b) When sodium hydroxide chemically reacts with ammonium chloride then it forms ammonia, water and sodium chloride as follows.
Now, the total ionic equation will be as follows.
Cancelling the spectator ions from the above equation. Then the net ionic equation will be as follows.
An old star dies out, causing a supernova, causing hot gases to accumulate, creating the Sun.
