Question

drag each tile to the correct location. classify the chemical equations as being balanced or not balanced. 2co + 2no → 2co₂ + n₂ 6co₂ + 6h₂o → c₆h₁₂o₆ + o₂ h₂co₃ → h₂o + co₂ 2cu + o₂ → cuo balanced not balanced

Explanation:

Step1: Check first equation

For $2CO + 2NO
ightarrow2CO_2+N_2$, on the left - hand side, we have 2 C, 2 O from CO and 2 O from NO (total 4 O), 2 N. On the right - hand side, we have 2 C, 4 O in $2CO_2$ and 2 N in $N_2$. It is balanced.

Step2: Check second equation

For $6CO_2 + 6H_2O
ightarrow C_6H_{12}O_6+O_2$, on the left - hand side, we have 6 C, 12 H, 18 O. On the right - hand side, in $C_6H_{12}O_6$ we have 6 C, 12 H, 6 O and in $O_2$ we have 2 O (total 8 O). It is not balanced.

Step3: Check third equation

For $H_2CO_3
ightarrow H_2O + CO_2$, on the left - hand side, we have 2 H, 1 C, 3 O. On the right - hand side, in $H_2O$ we have 2 H, 1 O and in $CO_2$ we have 1 C, 2 O (total 3 O). It is balanced.

Step4: Check fourth equation

For $2Cu+O_2
ightarrow CuO$, on the left - hand side, we have 2 Cu and 2 O. On the right - hand side, we have 1 Cu and 1 O. It is not balanced.

Answer:

Balanced: $2CO + 2NO
ightarrow2CO_2+N_2$, $H_2CO_3
ightarrow H_2O + CO_2$
Not Balanced: $6CO_2 + 6H_2O
ightarrow C_6H_{12}O_6+O_2$, $2Cu+O_2
ightarrow CuO$
