Question

identifying parts of a chemical equation
identify each part of this chemical equation, which
describes the burning of methane and oxygen.
a (the entire green box):
b (the blue box):
c (the arrow):
d (the number):
e (the purple box):

Explanation:

• A (the entire green box): A chemical equation represents a chemical reaction. Here, it shows the reaction between methane and oxygen.
• B (the blue box): Reactants are the substances that undergo a chemical change. In this equation, \(CH_{4}\) (methane) and \(O_{2}\) (oxygen) are the reactants.
• C (the arrow): The arrow (\(

ightarrow\)) in a chemical equation means "reacts to form". It separates the reactants from the products.

• D (the number): In a chemical equation, the numbers (like \(2\) in \(2O_{2}\) and \(2H_{2}O\)) are coefficients. Coefficients indicate the relative amounts of each substance involved in the reaction.
• E (the purple box): Products are the new substances formed as a result of the chemical reaction. Here, \(CO_{2}\) (carbon dioxide) and \(H_{2}O\) (water) are the products.

Answer:

A. chemical equation
B. reactants
C. reacts to form
D. coefficient
E. products
