Copper(II) nitrate decomposes on heating according to the balanced equation give

Question

Copper(II) nitrate decomposes on heating according to the balanced equation given below.

Let's start the process of balancing this equation by counting the atoms of elements in parentheses.

There are ____ N atoms and  ______O atoms on the left side of the equation.

Remember that a coefficient of "1" is usually not entered when balancing a chemical equation.

Now that you know how to count atoms of elements within parentheses, balance the equation by entering whole-number coefficients in the equation.

Explanation / Answer

Cu(NO3)2 ---> CuO + NO2 + O2

There are 2 N atoms and 6 O atoms on the left side

There are 1 N atom and 5 O atoms on the right side.

Both left and right side has 1 Cu atom.

Balanced equation-

2Cu(NO3)2 ---> 2CuO + 4NO2 + O2

There are 4 N and 12 O atoms on the left side.

There are 4 N and 12 O atoms on the right side.
