Answer:
Lactose is found in animal milk is lactase is the enzyme that is required to digest it.
Explanation:
Lactose is a disaccharide made of glucose and galactose units. This sugar is naturally present in animal milk and it is digested (broken in its units) by the lactase enzyme.
Some people are lactose intolerant because their bodies is not able to produce the enzyme. If they ingest dairy products it may cause health issues. Nowadays it is possible to purchase the lactase enzyme and ingest it with a dairy food to avoid any health effects.
Answer: Option (a) is the correct answer.
Explanation:
Entropy means the degree of randomness present within the molecules of an object.
When a substance is present in a solid state then its molecules are held together because of strong intermolecular forces of attraction.
As a result, molecules are not able to move freely and therefore, there will be no randomness.
But when a substance changes into liquid state then its molecules mover further apart from each other due to gain in kinetic energy. Hence, randomness increases.
On the other hand, when a substance moves from liquid to gaseous state then its molecules gain more kinetic energy due to which there will be high degree of randomness.
Therefore, as the products in the given reaction are present in liquid and gaseous state. So, this means that there has been an increase in entropy.
A decrease in entropy is represented by negative sign and an increase in entropy is represented by a positive sign.
Thus, we can conclude that the sign of
for the given reaction is
> 0.
The pair of both compounds that have the same empirical formula are C6H12O6 and HC2H3O2. The answer is letter D. <span>H2O and H2O2, BaSO4 and BaSO3 and FeO and Fe2O3 do not have the same empirical formula.</span>
