Formula:
Hydrogen Chloride = HCl (Chemical Compound)
Sodium = Na (Chemical Element)
Reactants:
A simple definition of a reactant can be the substances that go into a chemical reaction. By substances I mean any chemical.
Products:
A simple definition of a product can be the substances produced at the end of the reaction. Again by substances I mean any chemical.
Definition of the answer:
We know that Sodium is a Chemical Element and as decribed in the picture it was mixed by Hydrogen Chloride and we know that is a Chemical Compound. So in this case the Na CI can be the product that was produced at the last and it was the result after the chemical reaction was taken place. The reactant can be the Sodium. I chose that because Reactant is a substance/chemical that goes into a chemical reaction. So as seen in the picture it went into the beaker.
Hope this helps.
Answer:
True.
Explanation:
The world systems theory is a fundamental social evolution theory which states that, some developed countries such as core nations benefit while other countries such as peripheral (underdeveloped) nations are being exploited significantly.
According to world systems theory, peripheral nations become economically dependent on core nations, which keeps them at a low level of modernization.
Basically, the world systems theory divide the world into three (3) main categories and these includes;
I. Peripheral nations: these includes countries that provide cheap labor and other resources for the core nations. Some examples of peripheral nations are Haiti, Nigeria, Kenya, Sudan, Philippines, Chad, Niger etc.
II. Core nations: these are technologically advanced and well-developed countries that benefit from peripheral nations. Some examples of core nations are Germany, China, Japan, United States of America, England, France etc.
III. Semi-peripheral nations: these includes countries that are in between core and peripheral nations such as developing countries.

Answer: An empirical generalization
Explanation:
An empirical generalization in research, is an inference made after observing the relationship between two or more variables under different conditions.
In a research, this is the step after hypothesis and observation. The first step here is a question about correlation of fear of crime and police presence in a community. By proving that there is no relationship between these two variables, the researcher can move on to theory building where he/she reconciles their discoveries and knowledge of related fields.
