Determine how many atoms of pure silver will be created when 19.83 x 1023 atoms of copper are used in the following reaction:
cu + 2agno3 -> cu(no3)2 + 2ag
avogadro's number: 6.02 x 1023

Answer : The number of silver atoms produced will be

Explanation : Given,

Number of atoms of copper =

The given balanced chemical reaction,

From the balanced chemical reaction we conclude that,

As, number of copper atoms react to give number of silver atoms.

So, number of copper atoms react to give number of silver atoms.

Therefore, the number of silver atoms produced will be

radioactive decay occurs in unstable atomic nuclei – that is, ones that don't have enough binding energy to hold

the nucleus together due to an excess of either protons or neutrons.

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current
