Answer:
The one element is substituted in place of other element in compound.
Explanation:
Single replacement:
It is the reaction in which one elements replace the other element in compound.
AB + C → AC + B
For example:
Consider the reaction between zinc and silver nitrate. In this chemical reaction the zinc is substituted in place of silver in silver nitrate compound.
Chemical equation:
2AgNO₃ + Zn → ZnNO₃ + 2Ag
The starting material consist of compound ( AgNO₃) and pure element (Zn).
After reaction a new compound ( ZnNO₃) and pure element (Ag) is generated.
Answer:
It gives the number of protons in the nucleus of each atom of that element.
Explanation:
Draw CO2, C in the middle and O on each side. O has 6 e- and C has 4, so 6+6+4= 14 e-.
