Which of these is the correct word equation for the reaction, 4 Fe (s) + 3O2 (g) → 2FeO3 (s)?

1 answer:

6 0

The correct answer is
solid iron reacts with oxygen gas to form solid iron (III) oxide.
The state symbol (s) indicates that iron and iron oxide are in the solid state while the state symbol (g) indicates that oxygen gas is present in the gaseous state.
Moreover, the compound formed has iron (III) as the cation because two moles of iron (III) atoms bind with three moles of oxygen atoms.

Question 2Classify the following organic structures:CH3OCH3CH2CH2CHCH2CH3CH3NHCH3CH3CH(OH)CH₂CH3

Naily [24]

Within the options, we have four organic compounds. Let's see what the skeletal structure of the compounds is in order to identify them better:

The first compound CH3OCH3 has two methyl groups linked by a carbon atom, this type of compound is called an Ether

The second compound has a double bond, it is badly written but it seems that is an alkene.

The third compound has two methyl groups linked by nitrogen atoms, therefore will be an amine.

The last compound has a hydroxyl group, therefore it is an alcohol

Answer:

CH3OCH3 Ether

CH2CH2CHCH2CH3 Alkene

CH3NHCH3 Amine

CH3CH(OH)CH₂CH3 Alcohol
