Question

this passage describes a chemical reaction. read the passage. then, follow the instructions below. some chemical factories make hydrogen gas (h₂) using a process called steam methane reforming. in this process, methane (ch₄) combines with steam (h₂o) at high temperatures to form a mixture of hydrogen gas and carbon monoxide (co). this mixture can then be used to make substances like hydrogen fuel and ammonia. complete the table to classify the substances in this chemical reaction. substance reactant product carbon monoxide (co) hydrogen (h₂) methane (ch₄) steam (h₂o)

Explanation:

Reactants are substances that undergo a chemical change (they are on the left side of the chemical equation). Products are the new substances formed (on the right side of the chemical equation). According to the passage, methane (\(CH_4\)) and steam (\(H_2O\)) combine (react) to form hydrogen gas (\(H_2\)) and carbon monoxide (\(CO\)). So, \(CH_4\) and \(H_2O\) are reactants, while \(H_2\) and \(CO\) are products.

Answer:

Substance	Reactant	Product
hydrogen (\(H_2\))		\( \checkmark \)
methane (\(CH_4\))	\( \checkmark \)
steam (\(H_2O\))	\( \checkmark \)
