Is evaporation of water considered a chemical reaction? No because it’s a physical change. Some reactions have gases as a product and some do not. Just because there’s a gas doesn’t mean a chemical reaction has occurred.

elect the false statement. Which of the given statements is not a reason why reactions are performed under reflux? Refluxing all
Tatiana [17]

Answer:

Refluxing allows thermally unstable reactants to react faster without decomposition.

Explanation:

Reflux is an experimental laboratory technique, used to produce heating reactions that take place at temperatures higher than room temperature and where it is better to maintain a constant volume in the reaction. By means of this mechanism, it is possible to avoid losing solvent in the course of the process, and therefore, without releasing it into the atmosphere. This is used to heat mixtures for a long time at a certain temperature. As the temperature increases, the reactant particles collide more times and, because they have more energy, there are more particles that exceed the activation energy, which leads to more effective collisions and a higher reaction speed.
