Identify the type of reaction: Combustion reactions involve a substance reacting with oxygen to produce oxides, typically carbon dioxide and water.
For each reaction, write the unbalanced equation with the expected products: a. C(s) + O_2(g) → CO_2(g), b. C_3H_8O(l) + O_2(g) → CO_2(g) + H_2O(g), c. CS_2(s) + O_2(g) → CO_2(g) + SO_2(g), d. C_4H_6(g) + O_2(g) → CO_2(g) + H_2O(g).
Balance the carbon atoms first by ensuring the number of carbon atoms on the reactant side equals the number of carbon atoms in the carbon dioxide on the product side.
Next, balance the hydrogen atoms by adjusting the number of water molecules on the product side to match the hydrogen atoms in the reactants.
Finally, balance the oxygen atoms by adjusting the number of O_2 molecules on the reactant side to match the total number of oxygen atoms needed in the products.
