Convert this word equation into a balanced formula equation, please.
valentina_108 [34]

Answer:

3Cu(NO3)2 + 2Al —> 2Al(NO3)3 + 3Cu

Explanation:

From the question given above,

Copper (II) nitrate reacts with aluminum to form aluminum nitrate and copper. This can be obtained represent as follow:

Cu(NO3)2 + Al —> Al(NO3)3 + Cu

Thus, we can balance the above equation as follow:

Cu(NO3)2 + Al —> Al(NO3)3 + Cu

There are 2 atoms of N on the left side and 3 atoms on the right side. It can be balance by putting 3 in front of Cu(NO3)2 and 2 in front of Al(NO3)3 as shown below:

3Cu(NO3)2 + Al —> 2Al(NO3)3 + Cu

There are 3 atoms of Cu on the left side and 1 atom on the right side. It can be balance by putting 3 in front Cu as shown below:

3Cu(NO3)2 + Al —> 2Al(NO3)3 + 3Cu

There are 2 atoms of Al on the right side and 1 atom on the left side. It can be balance by putting 2 in front of Al as shown below:

3Cu(NO3)2 + 2Al —> 2Al(NO3)3 + 3Cu

Thus, the equation is balanced.
