Anestetic [448]3 years ago

<u>Answer:</u> The molar mass of water is 18 g/mol

<u>Explanation:</u>

Molar mass of a compound is defined as the sum of mass of every element each multiplied by the number of atoms of that element.

We are given a compound having chemical formula H_2O

Molar mass of hydrogen = 1 g/mol

Molar mass of oxygen = 16 g/mol

Mass of water = [(2\times 1)+16]=18g/mol

Hence, the molar mass of water is 18 g/mol

A scientist develops a new experiment to test atomic theory. His results do not agree with the theory.
slamgirl [31]

Answer:

When the results of a new experiment to test atomic theory do not agree with the theory, scientist will repeat the experiment to make sure that his results are reliable.

Explanation:

In the scientific context, each new experiment must be performed with precision and following the steps of the scientific method.

An experiment that does not provide reliable data to demonstrate a theory must be reviewed in detail and performed again to confirm the data obtained in the first attempt.

A theory is a postulate that tries to explain a natural phenomenon, but whose argument can be discussed or does not have the acceptance of a law. When the theory is proven and there are no arguments against it, it can be universally accepted and becomes a law.

The other options are not valid due to:

  • <u><em>Scientists worldwide will reject atomic theory because of the new results</em></u><em>.  A theory cannot be discarded without solid arguments or evidence in order to dismiss it and establish a new one.</em>
  • <u><em>The scientist will change his results to agree with the accepted theory</em></u><em>.  This would be an unethical procedure and unacceptable to the scientific community.</em>
  • <em><u>Other scientists will reject the results because they do not agree with the theory</u></em><em>. The opinion of other scientists is not enough to dismiss a theory, if it has a valid scientific basis.</em>
