Answer:
C
Explanation:
For A, 2Al(OH)3 contains 6H on the left side of the equation but only has 3H on the right side of the equation, thus its not balanced
For B, there is 2(Al2), which is 4, on the left side of the equation but only 2Al on the right side of the equation, so it is not balanced.
For D, theres a total of 6 H on the left side of the equation as there is (OH)3 and 3H, but none of the right side, so its not balanced.
C is the correct answer as
on the left side of the equation:
2 Al(OH)3 has 2Al, 6O, and 6H
on the right side of the equation:
Al2O3 has 2Al and 3O
3 H20 has 3H and 6O
this makes a total of 2Al, 6H and 6O, which is equal to the number of each element in the left side, thus it is balanced and is the right answer.
In the future for these type of qns, you want to add up the number of each element on the left, then the ride, and see compare the numver of element they have. if the number of all the elements on both sides are the same, the equation is balanced.

Answer:
an inducer
Explanation:
An Enzyme is a protein molecule found in cells which work as biological catalysts.
They speed up chemical reactions in the body, but do not get used up in the process, and can be used over and over again.
In chemistry inducers are molecules that regulates gene expression, and can bind to protein repressors or activators.
Lactose here acts as an inducer because it inactivates the repressor of an operon.
