Question
Classify the chemical equations as being balanced or not balanced.
2CO + 2NO → 2CO2 + N26CO2 + 6H2O → C6H12O6 + O2H2CO3 → H2O + CO22Cu + O2 → CuO
Solution
-
2CO + 2NO → 2CO2 + N2: This equation is balanced. On both sides of the equation, there are 2 carbon atoms, 2 nitrogen atoms, and 4 oxygen atoms.
-
6CO2 + 6H2O → C6H12O6 + O2: This equation is not balanced. On the left side of the equation, there are 6 carbon atoms, 12 hydrogen atoms, and 24 oxygen atoms. On the right side of the equation, there are 6 carbon atoms, 12 hydrogen atoms, and 18 oxygen atoms.
-
H2CO3 → H2O + CO2: This equation is balanced. On both sides of the equation, there are 2 hydrogen atoms, 1 carbon atom, and 3 oxygen atoms.
-
2Cu + O2 → CuO: This equation is not balanced. On the left side of the equation, there are 2 copper atoms and 2 oxygen atoms. On the right side of the equation, there is 1 copper atom and 1 oxygen atom.
