The flask was placed in a water bath for the entire duration of the experiment. The purpose of this was to___. A. heat up the flask to maximize the gas pressure

B. cool down the flask to maximize the gas pressure

C. keep the temperature constant so the collected
gas will not expand

C. keep the temperature constant so the collected  gas will not expand

Explanation:

A water bath is an instrument in the laboratory used for controlled temperature experiment. It is used to maintain a constant temperature of volume of samples of water, air or chemicals. It consist of water being heated at a regulated and required temperature. Where the volume of the sample is placed in the water bath during an experiment so as to avoid unnecessary expansion of the sample.

In the question given, the purpose of putting the flask in a water bath during the experiment is to ensure that the content of the flask is at a constant temperature and avoid unnecessary expansion. Thus the correct option is C.

what is the general relationship between a galaxy's distance from earth and its speed?

the answer is:

the farther away a galaxy is from us, the faster it is moving away from us.

every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.
