Answer:

The correct answer is c) a chemical change, because a gas was produced.

Explanation:

Sometimes when performing scientific experiments in laboratories, chemical changes are obtained in the elements that have been used, a chemical change is an alteration in the structure of a compound, so the element is different than at the beginning of the experiment.

Generally, when there is a chemical change this is usually irreversible; For example, in the case of Nio, he experiments with yeast, water, and sugar, which puts it in a bottle and closes it with a balloon, this mixture of substances has resulted in a chemical change since the element is transformed in gas.

Which political group seeks to expand liberty above all other principles and wishes to minimize government intervention in the e
alexandr1967 [171]

The libertarian political group. All libertarians have a conception of personal autonomy that focuses on civil liberties and a reduction or elimination of the state.

Libertarians <u>do not believe in state authority and power. They seek political freedom and autonomy, emphasizing freedom of choice, voluntary association and individual judgment. They argue that where there is a government, it should not violate the rights of any individual (the right to life, the right to freedom of expression and action, and the right to property).</u>

Libertarians do not believe in the omnipotent state and defend the rights of the individual. That means all individuals have the right to exercise exclusive dominion over their own lives, and have the right to live in the manner they choose, as long as they do not interfere with the equal rights of others.

<em>In other words, people should not be forced to sacrifice their lives and property for the benefit of others. They should be left free by the government to deal with each other as free traders (free market).</em>

How was Darius able to maintain control of a large empire
olga2289 [7]

Darius of Persia maintained control over his empire by the use of provincial governors known as satraps. These satraps ruled areas that were larger than most kingdoms throughout the world, giving them tremendous power and wealth over their division of the empire. Satraps had a number of responsibilities, most notably needing to pay an annual tribute to the emperor and raising soldiers from their province during a time of war. By delegating authority to satraps, Darius was able to make decisions that affected all his empire rather than one region, and whenever he needed a military force (such as during the Persian wars with Greece), he could mobilize the largest army on Earth.
