Answer :
There are three processes involved in the conversion of ethane to ethanoic acid.
In first process, on the chlorination of the ethane in the presence of the sunlight or in the presence of U.V light, ethane converted into ethyl chloride.
In the second process, ethyl chloride react with the aqueous potassium hydroxide to give ethanol.
In the third process, ethanol react with an oxidizing agent (Alkaline potassium permanganate) to give ethanoic acid.
The reaction are shown below.
TRUE
FALSE
Answer:
FALSE
Explanation:
The claim that ancient philosophers did not conduct experiments or detailed observations is false. Philosophers like Aristotle made extensive contributions to biology through observation, and Hellenistic scholars conducted early forms of experimental research.
The statement that ancient philosophers discussed the world around them but did not do any experiments or detailed observations is FALSE. While it is true that some ancient philosophers, particularly in the early stages of Greek philosophy, were more speculative in nature, others, such as Aristotle, engaged in detailed observations and can be considered early scientists. For example, Aristotle conducted extensive studies on biology, classifying a vast number of species and making observations on their life cycles, habits, and anatomy.
Throughout history, methodologies have varied, and while the ancient philosophers didn't conduct experiments in the modern sense, they did employ various forms of inquiry to understand the world. Furthermore, in the Hellenistic period, scholars at institutions like the Library of Alexandria did indeed conduct forms of research that could be seen as experimental, such as Eratosthenes estimating the Earth's circumference.

Answer;
D. C6H6, C2H5OH, C6H5CH3, and C3H5(NO3)3.
Explanation;
-Organic compound are chemical compounds in which one or more atoms of carbon are covalently linked to atoms of other elements, most commonly hydrogen, oxygen, or nitrogen, like the examples above in choice D. . Inorganic Compoundson the other hand, are compounds made from any elements except those compounds of carbon, such as CaSO4, CaCl2 and Ca3(PO4)2 in A, B and C respectively.
b. results in "smokers breath."
c. can lead to premature aging.
Smoking marijuana can be as unhealthy as smoking cigarettes and can cause cancer.
a. can cause cancer.
Smoking marijuana can be as unhealthy as smoking cigarettes, and it can cause cancer. Marijuana smoke contains many of the same harmful chemicals as cigarette smoke, including tar, carbon monoxide, and carcinogens. These chemicals can damage DNA and lead to the development of cancer.
In addition to cancer, smoking marijuana can also lead to other health problems, such as respiratory problems, heart disease, and lung infections. It can also impair cognitive function and increase the risk of accidents.
The other options, b. results in "smokers breath" and c. can lead to premature aging, are also possible effects of smoking marijuana, but they are not as serious as cancer.
