What is a synthesis reaction?
a reaction that occurs when one element within a compound is exchanged with another element
a reaction that occurs when a single substance breaks apart and forms two or more new substances
a reaction that occurs when a substance combines with molecular oxygen, releasing light and energy
a reaction that occurs when two or more reactants combine into one product
It is the last one right?
Yes but the one before that COULD be right under the right circumstances. I'm sure the last one is the intended answer.
Yes, you are correct. A synthesis reaction is a reaction that occurs when two or more reactants combine to form a single product. In this type of reaction, the reactants come together to produce a more complex substance. This is also commonly referred to as a combination reaction. An example of a synthesis reaction is the formation of water (H2O) from hydrogen (H2) and oxygen (O2) gases.
To find the answer to your question, you can use your knowledge and understanding of chemistry concepts. The term "synthesis reaction" itself can provide a clue, as it implies the combining or synthesis of substances. By eliminating the other choices and understanding the concept of synthesis reactions, you can conclude that the correct answer is "a reaction that occurs when two or more reactants combine into one product."
