Answer the following question given this paragraph: Chemists want to be able to predict the outcome of reactions. They would like it to be possible to predict what will happen when reactants are added together under a given set of conditions. The conditions of a reaction might include things like temperature, pressure, and concentrations of various reaction components. If the given conditions favor the formation of products, the reaction is said to be spontaneous . Q: How is a reaction described when the given conditions favor formation of products? Choices: - instantaneous - fluctuations - planned - spontaneous A:
spontaneous

Ques: Answer the following question given this paragraph: Distillation is an effective method to separate mixtures comprised of two or more pure liquids. Distillation is a purification process where the components of a liquid mixture are vaporized and then condensed and isolated. In simple distillation, a mixture is heated and the most volatile component vaporizes at the lowest temperature. The vapor passes through a cooled tube (a condenser), where it condenses back into its liquid state. The condensate that is collected is called distillate. Q: What is a purification process where the components of a liquid mixture are vaporized and then condensed and isolated? Choices: - conduction - sterilization - dispersion - distillation A:
Ans: distillation

(A).
beating
