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.

Hello. This question is incomplete. The full question is:
"Dr. Parrett is a sports psychologist for a large Southern university. The provost and chancellor have asked him to examine the relationship between athletic performance and academic stress at the university. For example, is it the case that the most talented athletes experience the greatest concern over their grades? The provost and chancellor have made it clear to Dr. Parrett that they want a large amount of external validity in the study. He has valid and reliable measures of both athletic performance and academic stress. He knows that he does not have the time or the money to study the entire population of interest.
Imagine that Dr. Parrett wants to use a nonrepresentative sampling technique. Name the three types of nonprobability sampling and explain how each one could be used by Dr. Parrett."
Answer:
The four types of nonprobability sampling are convenience sampling, purposive sampling, quota sampling, and snowball sampling.
Explanation:
Convenience sampling: Allows a selection to be made of a small sample of the target population of the research. This sample is made up of individuals who are available and accessible to research and not through statistical criteria. Regarding the question above, Dr. Parrett can select the athletes he knows and who would like to participate in the research.
Purposive sampling: It allows the sample to be controlled whenever a certain manipulation is possible to generate expected and known results. In the case of the question above, Dr Parrett can search for specific athletes, with characteristics that will generate an expected result in the research.
Snowball sampling: Allows the individuals who make up the sample to invite other individuals to compose the sample, who in turn can invite other individuals. In the case of the question above, Dr. Parret can invite the athletes he wants and ask them to call friends to participate in the survey as well.
Sampling quota: Allows the individuals who will compose the sample to be selected due to their characteristics and qualities. Regarding the question above, Dr. Parrett could only summon athletes with high marks.
The relationship between the prices of apple and demand is : <u>A Negative correlation </u>
<h3>Negative correlation </h3>
A negative correlation occurs when an increase in one variable leads to a decrease in value of the other variable.
As the price of goods and service go up in the open market, the demand for the goods and services goes down, this kind of relationship is known as an Negative correlation.
For Kelvin to have an increase in demand he must decrease the price of the apples.
Hence we can conclude that The relationship between the prices of apple and demand is a<u> Negative correlation </u>
