Answer:
The correct answer is option (3) "using nonviolent tactics such as boycotts and hunger strikes".
Explanation:
Cesar Chavez was a leader of American labor and civil right activists that fought to unionized migrant farm workers by the creation of The National Farm Workers Association. Cesar Chaves used nonviolent tactics to support the migrant farm workers. For instance, when Filipino American farm workers protested for higher wages in 1965, he encouraged Americans to boycott table grapes to support them; while he once performed a 24-day hunger strike in 1972 in the Santa Rita Center as a response to Arizona prohibiting boycotts and strikes by farm workers.

When a catalyst is added to a system the equilibrium concentration remains unchanged. A catalyst increases the activation energy of the forward reaction. The correct option is 2.
A substance which increases the rate of a reaction without itself undergoing any permanent change chemically or quantitatively is defined as the catalyst and the phenomenon is known as the catalysis. It is believed that a catalyst usually participates in the chemical reaction and it speeds up.
In short, the catalyst lowers the energy barrier and thereby provides a different path of lower activation energy for the reaction so that the rate of the reaction increases.
A catalyst speeds up both the forward and backward reactions to the same extent and does not alter equilibrium constant. Thus it speeds up the attainment of equilibrium faster.
Thus the correct option is 2.

Answer:
Tricontanyl palmitate: CH₃-(CH₂)₂₉-O-CO-(CH₂)₁₄-CH₃
Explanation:
Beeswax is a tough natural wax which is produced by the worker honey bees. The beeswax is an ester of the long chain fatty acids and alcohols. One of the major components of beeswax is tricontanyl palmitate.
Tricontanyl palmitate is a wax ester that is composed of 16-carbon fatty acid and a 30-carbon alcohol, joined by an ester linkage.
The molecular structure of tricontanyl palmitate is:
CH₃-(CH₂)₂₉-O-CO-(CH₂)₁₄-CH₃
Answer: D. A buildup of mostly methane gas, which is pontentially explosive.
Explanation:
Firedamp refers to a gas mixture, largely methane, that appear in underground coal mines. It is explosive at concentrations between 5 and 10% in the air.
