The process by which complex compounds are broken down by enzymes and by which many organic alcohols are formed is called fermentation.
a. true
b. false

The given statement is true.

Explanation:

When there occurs changes in organic substrates with the help of enzyme action then this process is known as fermentation. This process results in the formation of alcohols.

For example, process of fermentation occurs in yogurt, pickles, beers, wine etc.

Also equation for alcoholic fermentation is as follows.

Therefore, we can conclude that the given statement process by which complex compounds are broken down by enzymes and by which many organic alcohols are formed is called fermentation, is true.

1. 1 mole of anything contains 6.022x10^23 pieces  

d  

2. a  

3. c, number  

5. 1.24x10^24atoms / 6.022x10^23atoms/mole = 2moles h2 atoms  

6. fe2br3 mass = 2moles x mass fe + 3 moles x mass br  

molar mass = grams / number of moles = g/mole  

to find moles = g / molar mass  

to find mass = g = molar mass / moles
