Question

Which of the following shows the combustion of a hydrocarbon?
OA. NaOH + HCI → NaCl + H₂O
OB. CO₂ + H₂O → H₂CO3
OC. 2C₂H₂ +502 + 4CO2 + 2H₂O
OD. C₂H4 + Cl₂ ⇒ C₂H4Cl₂

Answer 1

Answer:

C.) 2 C₂H₂ +5 O₂ --> 4 CO₂ + 2 H₂O

Explanation:

*None of these answers perfectly display the combustion of a hydrocarbon, so I chose the one that looks most similar*

The combustion of a hydrocarbon (CₙH₂ₙ₊₂) occurs when a hydrocarbon reacts with oxygen gas (O₂) and produces carbon dioxide (CO₂) and water (H₂O).
