Answer

1. C + O_2 \rightarrow CO_2 2. N_2 + O_2 \rightarrow N_2O_5 3. N_2 + H_2 \rightarrow NH_3 4. C_2 + H_2 \rightarrow C_2H_6 5. CH_4 \rightarrow C + H_2 Use the color key to model each atom in these unbalanced reactions. Explanation 1. Write Unbalanced Reactions List the unbalanced chemical equations as given or requested. 1. C + O_2 \rightarrow CO_2 2. N_2 + O_2 \rightarrow N_2O_5 3. N_2 + H_2 \rightarrow NH_3 4. C_2 + H_2 \rightarrow C_2H_6 5. CH_4 \rightarrow C + H_2 2. Draw/Model Unbalanced Reactions (Color Key) Assign colors to each element for modeling: - Red = Hydrogen (H) - Black = Carbon (C) - Blue = Oxygen (O) - Green = Nitrogen (N) - Yellow = Sulfur (S) - Orange = Sxpgen (likely a typo, ignore unless specified) - Purple = Chlorine (Cl) - Pink = Potassium (K) **Example for 1st reaction:** - Reactants: 1 black (C), 2 blue (O) - Products: 1 black (C), 2 blue (O) together Repeat similar color assignments for other reactions.
