Question

Which of the following reactions is a synthesis reaction?

Answer 1

Answer:

B) 4H₂(g) + O₂(g) ⟶ 2H₂O(l)

Explanation:

• Chemical reactions occur when compounds or elements combine to form new compounds or other elements.
• Chemical reactions may be classified into various types which include synthesis reactions, replacement reaction, decomposition reactions, and precipitation reactions among others.
• In our case, we were supposed to identify a synthesis reaction.
• Thus, we need to know what is a synthesis reaction.
• A synthesis reaction is a reaction that occurs when two elements or small compounds combine to generate a large compound.
• In this case, B is the choice that shows a synthesis reaction where hydrogen gas combines with oxygen gas to yield water.
