Answer 2

The chemical equation you've provided represents a chemical reaction between tin(IV) oxide (SnO2) and carbon monoxide (CO) to produce tin (Sn) and carbon dioxide (CO2). This is a balanced chemical equation, as the number of atoms of each element on both sides of the equation is the same:

On the left side (reactants):

• Sn: 1 atom
• O: 2 atoms (from SnO2)
• C: 2 atoms (from 2CO)

On the right side (products):

• Sn: 1 atom
• O: 2 atoms (from 2CO2)
• C: 2 atoms (from Sn)

So, the equation is balanced with 1 Sn, 2 O, and 2 C atoms on both sides. This reaction represents the reduction of tin(IV) oxide by carbon monoxide to produce tin metal and carbon dioxide gas.
