water filtration systems work by capturing undesirable elements in the water and allowing only clean water through. Water filtration systems for residential use that use actual filters, such as the thin film composite in reverse osmosis, do this by using microscopic pores that block even small bacteria while letting water through. Others work through other materials such as activated carbon or sand, which essentially scrubs the water clean.
It is necessary to classify organisms because: ... It helps in the identification of living organisms as well as in understanding the diversity of living organisms. Classification helps us to learn about different kinds of plants and animals, their features, similarities and differences.
A
Answer:
B. Dehydration
Explanation:
Addition reaction is defined as the chemical reaction in which two different compunds combine together to form a new compund.
Dehydration reaction is defined as the chemical reaction in which water molecule (H2O) is removed from the reactant.
For example: RCO2H + R′OH ⇌ RCO2R′ + H2O
In the given equation: CH3OH + HOCH3 = CH3-O-CH3 + HOH
The reaction is showing dehydration because two molcules are combined aand water molecule is eliminated from the reactant.
Hence, the correct option is B. Dehydration.
