Question

the following chemical equation represents how plants make glucose and oxygen using carbon dioxide and water in the presence of sunlight:

6co₂ + 6h₂o → c₆h₁₂o₆ + 6o₂

complete the statements.

• in a chemical, the coefficients show how many copies of each subst in the reaction.

• the subscri show how many atoms of each element are in a single substar

• to count the t_iber of oxygen atoms in \6co₂\, take the coefficient of and multiply by the subscript of.

Explanation:

In a chemical equation, coefficients indicate the number of molecules or formula units of a substance involved in the reaction. Subscripts show the number of atoms of each element within a single molecule or formula unit. For counting atoms in a compound with a coefficient (e.g., \(6CO_2\)), multiply the coefficient by the subscript of the relevant element (here, oxygen).

Answer:

• In a chemical equation, the coefficients show how many copies of each substance are in the reaction.
• The subscripts show how many atoms of each element are in a single substance.
• To count the total number of oxygen atoms in “\(6CO_2\)”, take the coefficient of \(CO_2\) (which is \(6\)) and multiply by the subscript of \(O\) (which is \(2\)). So the total number of oxygen atoms is \(6\times2 = 12\).
