question 222 of 228. the following is a partial chemical equation:? → 2h₂ + o₂. what can you infer about the reactants in this reaction? a. the reactants include 4 hydrogen molecules and 2 oxygen molecules. b. the reactants include 4 hydrogen atoms and 2 oxygen atoms. c. the reactants include 2 hydrogen molecules and 1 oxygen molecule. d. the reactants include 2 hydrogen atoms and 1 oxygen atom.

Answer

Brief Explanations:

In a chemical reaction, atoms are conserved. Products are 2H₂ (4 H atoms) and O₂ (2 O atoms). Reactants must have equal H and O atoms.

Answer:

B. The reactants include 4 hydrogen atoms and 2 oxygen atoms.
