Question

1. combination reactions can be generalized as: a + b → ab express the combination reaction of iron and oxygen as a chemical equation. hint: it is not necessary to balance the equation. a + b → ab choices: fe fe2 o o2 o3 feo feo2 fe2o3 submit answer 0 / ∞ submissions used heads up! you need to submit this answer for it to save and be graded. score: 0/1

Explanation:

Step1: Identify reactants

Iron is represented as Fe and oxygen in air is $O_2$.

Step2: Determine product

When iron reacts with oxygen, one of the common products is $Fe_2O_3$.

Step3: Write chemical equation

$Fe + O_2
ightarrow Fe_2O_3$

Answer:

$Fe + O_2
ightarrow Fe_2O_3$
