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.

What are two reason that the us government encouraged the destruction of bisons?
hram777 [196]
The government wanted to weaken Native Americans so white settlers could migrate easier. Native Americans needed bison for their hides and sustenance. They also believed bison were sacred animals. Reducing bison weakened Native Americans in numerous ways. They were then forced to move from their locations to reservations so they could survive. The destruction of the bison was also the government's way to control the Native Americans.

Hope this helps! :)
