Is the following formulation of a task correct? If not, please correct it: Complete and balance each combustion reaction equation. a. S(s) + O2(g) → b. C3H6(g) + O2(g) → c. Ca(s) + O2(g) → d. C5H12S(l) + O2(g) →
Verified step by step guidance1
Identify the reactants and products in each combustion reaction. Combustion typically involves a substance reacting with oxygen to form oxides.
For each reaction, write the unbalanced chemical equation. For example, for reaction (a), write S(s) + O_2(g) → SO_2(g).
Balance each equation by adjusting the coefficients to ensure the same number of each type of atom on both sides of the equation. Start with the most complex molecule.
Check that the number of atoms for each element is equal on both sides of the equation. Adjust coefficients as necessary to achieve balance.
Verify that the balanced equation follows the law of conservation of mass, meaning the total mass of reactants equals the total mass of products.
