Answer:
P=19.32g/cm³
Explanation:
m=9.66g
v=0.5cm³
P=mass/volume (density formula)
=9.66/0.5
=19.32g/cm³
Answer:
bad thing.
Explanation:
most of Greenland is an icy island with the only main population on the west coast.
Although this would probably open up more land for use; the rising sea levels are a much bigger threat comparatively with the perks of warmer climate.
Answer:
Elements that are in the same period have chemical properties that are not all that similar. Consider the first two members of period 3: sodium (Na) and magnesium (Mg). In reactions, they both tend to lose electrons (after all, they are metals), but sodium loses one electron, while magnesium loses two.

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>
