2 answers:
A theory is a .
Further Explanation:
Scientific Method:
This method includes thinking about any subject, scientific problem or content. Observation, hypothesis, comparison, organization, prediction, experimentation, evaluation and application are included in scientific method.
Scientific method includes steps as enlisted below.
- Understanding the experiment
- Pose a testable question
- Research the topic
- State a hypothesis
- Design the experiment
- Perform the experiment
- Data collection
- Draw conclusions
Experiment:
It is defined as procedure framed for a specific purpose. It involves dependent as well as independent variables.
Theory:
It is a well-tested explanation for the data. This is accomplished when several set of observations are recorded. It cannot be accepted by just a single contrasting result.
Observation:
This is type of information collected by human beings. It results in raising several questions that lead to further investigations. It is necessary to collect proofs for the respective investigations.
Hypothesis:
This is a proposed explanation for observation and is verified by an experiment.
Therefore a theory is defined as a well-tested explanation for broad set of observations.

A bond is non polar if it is between same atoms and polar if it is between different atoms.
Same atoms are like two dogs of same strength pulling a bone towards towards each other. But when it’s different atoms it’s like a big dog and small dog then the bone is more towards bigger dog. So it’s the same way in bonds.
Bonds are made up of electrons, when the more stronger pulling atom is present than other the electrons are more towards it and as a result we have polar bond. There is development of a kind of a negative pole and a positive pole.
The stronger atom has electrons towards itself so it has a little more negative charge while the other atom has positive charge. This makes bond polar.
So just look for bond between two different atoms, it would be polar.
Look at the pic below to see the answer.
Marked with green is bond between same atoms... one carbon and another carbon so it is not polar and test marked with blue are polar.
Well the answer should have been 10 but since the bonds at 3 and 8 are two of same type we count only one of them.
The answer is 8... well the answer should be 10 otherwise... discuss it with ur teacher
