Write the word equation to represent the reaction between hydrochloric acid and calciumhydrochloric acid + calcium → calcium chloride + waterhydrochloric acid + calcium → calcium chloride + hydrogenhydrochloric acid + calcium → calcium hydrochloride + waterhydrochloric acid + calcium → calcium hydrochlorideQuestion 1 of 10 Loading... 2. What are the advantages/disadvantages of using the fermentation of glucose to manufacture ethanol.Advantages: Uses continuous process which is efficient. Uses renewable resources, e.g sugar cane. Low temperature and pressure so low energy input. Disadvantages: Slow rate of reaction. Impure product.Advantages: Uses renewable resources, e.g sugar cane. Uses low temp and pressure therefore low energy input. Disadvantages: Uses batch process which is inefficient. Slow rate of reaction. Impure product.Advantages: Uses continuous process which is efficient. Uses renewable resources, e.g sugar cane. Pure product. Disadvantages: Slow rate of reaction. High temperature and pressure require high energy input .Advantages: Uses renewable resources, e.g sugar cane. Pure product. Disadvantages: Uses batch process which is inefficient.
