The idea that atoms are unstable would have been strengthened because the orbiting electron would lose energy and fall into the nucleus.
Omitted options and they are
a) pure compound.
b. pure element.
c. pure substance.
d. homogeneous solution.
e. heterogeneous solution
Answer:d. homogeneous solution.
Explanation:
Pure substances or elements or compounds have a definite and sharp melting or boiling point, Any substance that is not pure is impure and will have different temperature of melting or boiling points.
To this effect, the clear colorless liquid cannot be a Pure substance, element or compound.
We can therefore say that the clear colorless liquid would be a homogeneous solution because a homogeneous solution is a mixture of constituents which completely mixes together such that each constituents cannot be seen with naked eye, When heated to boiling, each constituent in the mixture will give different boiling points.
A heterogeneous Solution, too is a mixture but contains constituents that can be seen and not a clear colourless solution.
Therefore On the basis of this information, we can say that the material in the beaker was a Homogeneous solution
D. Sometimes it is necessary to put forth new theories to explain experimental results,
Explanation:
Creativity is important to science because sometimes, it is necessary to put forth new theories to explain experimental results.
Theories are explanation of scientific observations.
- Most scientists are critical and creative thinkers.
- They must be able to come up with a wide range of possible explanation to explain their findings.
- The explanations must be scientific in nature and not fall out of the basic tenets of this way of thinking.
- Therefore, scientists draw from their wealth of deductive reasoning to give explanations into an observed phenomenon.

Answer:
the density of the sample - the melting point of the sample
Explanation:
Intrinsic property is the property of matter which exists itself or within subject. In other words, it do not depend on the mass of the sample. An extrinsic property is not inherent or essential to subject which is being characterized. In other words, it depend on the mass of the sample.
For example,
Density, melting point are example of intrinsic property. Whereas, weight, volume are an example of extrinsic property.
Intrinsic properties helps to determine the matter. Thus, density of sample and melting point of sample is the answer.
