Answer:
Explanation:
A double displacement reaction is one in which exchange of ions take place. The salts which are soluble in water are designated by symbol (aq) and those which are insoluble in water and remain in solid form are represented by (s) after their chemical formulas.
A double displacement reaction in which one of the product is formed as a solid is called as precipitation reaction.
The balanced chemical equation is:
<u>Answer:</u> The nuclear binding energy of the given element is
<u>Explanation:</u>
For the given element
Number of protons = 3
Number of neutrons = (6 - 3) = 3
We are given:
M = mass of nucleus =
Calculating mass defect of the nucleus:
Converting this quantity into kg/mol, we use the conversion factor:
1 kg = 1000 g
So,
To calculate the nuclear binding energy, we use Einstein equation, which is:
where,
E = Nuclear binding energy = ? J/mol
= Mass defect =
c = Speed of light =
Putting values in above equation, we get:
Hence, the nuclear binding energy of the given element is
