the chemical equation shown represents a reaction between two reactants, carbon (c) and hydrogen (h₂). the reaction produces a substance called methane (ch₄). c + 2 h₂→ch₄. based on the chemical equation, which statement about conservation of mass is the most correct for this reaction? a mass is conserved because the h₂ remains together as h₄ instead of being split into individual h atoms. b mass is conserved because there are four hydrogen atoms and one carbon atom on both sides of the reaction arrow. c mass is not conserved because there are more hydrogen atoms in the product (four atoms) than in the reactants (two atoms). d mass is not conserved because there is one substance on the product side of the reaction arrow but two substances on the reactant side.

Answer

Brief Explanations:

The law of conservation of mass states that mass is conserved in a chemical reaction as the number and type of atoms are the same on both sides of the balanced chemical equation. In the given equation $C + 2H_2\rightarrow CH_4$, there is 1 carbon atom and 4 hydrogen atoms on both the reactant and product sides.

Answer:

B. Mass is conserved because there are four hydrogen atoms and one carbon atom on both sides of the reaction arrow.
