Question

which of the following best describes the number of atoms for each element in the chemical reaction?
oa. there are 6 carbon atoms, 12 hydrogen atoms and 18 oxygen atoms on the reactant side and 6 carbon atoms, 12 hydrogen atoms and 18 oxygen atoms on the product side
ob. there are 6 carbon atoms, 12 hydrogen atoms and 8 oxygen atoms on the reactant side and 6 carbon atoms, 12 hydrogen atoms and 18 oxygen atoms on the product side
oc. there are 6 carbon atoms, 12 hydrogen atoms and 18 oxygen atoms on the reactant side and 6 carbon atoms, 12 hydrogen atoms, and 3 oxygen atoms on the product side
od. there are 6 carbon atoms, 12 hydrogen atoms and 12 oxygen atoms on the reactant side and 1 carbon atom, 2 hydrogen atoms, and 3 oxygen atoms on the product side

Explanation:

Step1: Count atoms on reactant side

• Carbon: In the first reactant molecule, count carbon atoms. There are 6 carbon atoms.
• Hydrogen: Count hydrogen atoms in the first reactant molecule. There are 12 hydrogen atoms.
• Oxygen: Count oxygen atoms in both reactant molecules. First reactant has some oxygen (let's assume from structure) and second reactant (6 \(O_2\) molecules, so \(6\times2 = 12\) oxygen atoms from second reactant. Total oxygen on reactant side: \(6+ 12=18\) oxygen atoms.

Step2: Count atoms on product side

• Carbon: In the first product (\(CO_2\) - like structure, assume 6 carbon atoms as per conservation).
• Hydrogen: In the second product (\(H_2O\) - like structure, count hydrogen. There are 12 hydrogen atoms.
• Oxygen: First product (\(CO_2\) - like, assume \(6\times2 = 12\) oxygen from first product and second product (\(H_2O\) - like, \(6\times1=6\) oxygen. Total \(12 + 6=18\) oxygen atoms on product side.

Answer:

A. There are 6 carbon atoms, 12 hydrogen atoms and 18 oxygen atoms on the reactant side and 6 carbon atoms, 12 hydrogen atoms and 18 oxygen atoms on the product side.
