Why are alkanes classified as saturated hydrocarbons?They do not react easilyThey contain only single bondsThey are usually solids at room temperatureThey are toxic substancesQuestion 2 of 10 Loading... 3. What does this symbol represent?Rate of forward reaction equals rate of backwards reactionDynamic equilibriumYield of reaction is the same both waysReversible reactionQuestion 3 of 10 Loading... 4. What are the advantages/disadvantages of using the fermentation of glucose to manufacture ethanol.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 renewable resources, e.g sugar cane. Pure product. Disadvantages: Uses batch process which is inefficient. Slow rate of reaction. High temperature and pressure require high energy input .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 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 .Question 4 of 10 Loading... 5.
