Question

In the balanced chemical equation-               xCu + yHNO3        ---------->    xCu(NO3)2 + y/4[NO] + y/2[H2O] The values of x and y are respectively-​

Answer 1

Answer:

Given :

The equation is   Cu+ xHNO₃⇒ Cu(NO₃)₂+ yNO₂+2H₂O

To find :

The values of x and y

Solution :

This equation can be solved by balancing the number of elements present in the either side of the equation

Number of H on th products side is 4 which should be equal to the number of H on the reactants side

       The value of x = 4

As the value of x is 2 the number on N on the reactants side is 2 which should be equal to the number of nitrogen atoms on product side

      The value of y = 2

The equation is Cu+ 4HNO₃⇒ Cu(NO₃)₂+ 2NO₂+2H₂O
