Question

identify each part of this chemical equation, which describes the breakdown of water into hydrogen and oxygen. a (the entire green box): dropdown b (the blue box): dropdown c (the arrow): dropdown d (the purple box): dropdown

Explanation:

• For part A (entire green box): In a chemical equation, the entire expression showing reactants and products is the chemical equation itself.
• For part B (blue box: \(2H_2O\)): In a chemical reaction, the substances that react (on the left side of the arrow, usually) are reactants. Here, \(H_2O\) (water) is breaking down, so it's a reactant.
• For part C (the arrow): The arrow in a chemical equation represents the direction of the reaction, indicating the process of the reaction occurring, and is called the reaction arrow (or yield sign), showing that reactants are converted into products.
• For part D (purple box: \(2H_2 + O_2\)): The substances formed as a result of the reaction (on the right side of the arrow) are products. Here, hydrogen (\(H_2\)) and oxygen (\(O_2\)) are formed from water, so they are products.

Answer:

A (the entire green box): Chemical Equation
B (the blue box): Reactant
C (the arrow): Reaction Arrow (Yield Sign)
D (the purple box): Products
