(Do not label as “Introduction.” Title of paper goes at the top of the page—not bold)
The introduction of an APA-style paper is the most difficult to write. A good introduction will summarize, integrate, and critically evaluate the empirical knowledge in the relevant area(s) in a way that sets the stage for your study and why you conducted it. The introduction starts out broad (but not too broad!) and gets more focused toward the end. Here are some guidelines for constructing a good introduction:
Don’t put your readers to sleep by beginning your paper with the time-worn sentence, Past research has shown....(blah blah blah) They’ll be snoring within a paragraph! Try to draw your reader in by saying something interesting or thought-provoking right off the bat. Take a look at articles you’ve read. Which ones captured your attention right away? How did the authors accomplish this task? Which ones didn’t? Why not? See if you can use articles you liked as a model. One way to begin (but not the only way) is to provide an example or anecdote illustrative of your topic area.Although you won’t go into the details of your study and hypotheses until the end of the intro, you should foreshadow your study a bit at the end of the first paragraph by stating your purpose briefly, to give your reader a schema for all the information you will present next.Your intro should be a logical flow of ideas that lead up to your hypothesis. Try to organize it in terms of the ideas rather than who did what when. In other words, your intro shouldn’t read like a story of “Shirley did such-and-such in 1991. Then Gangelhoff did something-or-other in 1993. Then....(etc.)” First, brainstorm all of the ideas you think are necessary to include in your paper. Next, decide which ideas make sense to present first, second, third, and so forth, and think about how you want to transition between ideas. When an idea is complex, don’t be afraid to use a real-life example to clarify it for your reader. The introduction will end with a brief overview of your study and, finally, your specific hypotheses. The hypotheses should flow logically out of everything that’s been presented, so that the reader has the sense of, “Of course. This hypothesis makes complete sense, given all the other research that was presented.”When incorporating references into your intro, you do not necessarily need to describe every single study in complete detail, particularly if different studies use similar methodologies. Certainly, you want to summarize briefly key articles, though, and point out differences in methods or findings of relevant studies when necessary. Don’t make one mistake typical of a novice APA-paper writer by stating overtly why you’re including a particular article (e.g., “This article is relevant to my study because…”). It should be obvious to the reader why you’re including a reference without your explicitly saying so. DO NOT quote from the articles, instead paraphrase by putting the information in your own words.Be careful about citing your sources (see APA manual). Make sure there is a one-to-one correspondence between the articles you’ve cited in your intro and the articles listed in your reference section.Remember that your audience is the broader scientific community, not the other students in your class or your professor. Therefore, you should assume they have a basic understanding of psychology, but you need to provide them with the complete information necessary for them to understand the research you are presenting.METHOD An APA-style paper includes the following sections: title page, abstract, introduction, method, results, discussion, and references.

The rule for the determine of total magnification of an image is that:
When observing specimen with the aid of a microscope, you can get the amount of total magnification by using the power of the objective which exist in 4X, 10X, 40x form and multiply by the power of the ocular (eyepiece) which is often 10X.That is if ocular lens is: 10X (ocular) mutiplied by 4X (objective) = 40X will be the total magnification all togetherFor better understanding let's explain what the Total magnification means
Magnification is commonly referred to as the ratio of the size of a specimen (image) to the real size of that object Total magnification is simply known as what we get when objective lens is multiplied by the ocular lens. (e.g. 40x +10x = 400x)Note that in determining total magnification is done by the amount or number all together of the times a specific specimen that an individual is observing is magnified.Eyepiece is simply known to increase or magnifies a specific object.Objectives often exist in 4X, 10X, 40X and it simply increases or magnify the specimen size.From the above we can therefore say that the answer The rule for the determine of total magnification of an image is that:
When observing specimen with the aid of a microscope, you can get the amount of total magnification by using the power of the objective which exist in 4X, 10X, 40x form and multiply by the power of the ocular (eyepiece) which is often 10X.That is if ocular lens is: 10X (ocular) mutiplied by 4X (objective) = 40X will be the total magnification all together is correctLearn more about total magnification from:

Explanation:
A sample of a compound containing only carbon and oxygen decomposes and produces 24.50g of carbon and 32.59g of oxygen. what is the sample?
Answer : The sample is, CO (carbon monoxide)
Solution : Given,
Mass of C = 24.50 g
Mass of O = 32.59 g
Molar mass of C = 12 g/mole
Molar mass of O = 16 g/mole
First convert given masses into moles.
Moles of C = [tex]\frac{\text{ given mass of C}}{\text{ molar mass of C}}= \frac{24.50g}{12g/mole}=2.04moles[/tex]
Moles of O = [tex]\frac{\text{ given mass of O}}{\text{ molar mass of O}}= \frac{32.59g}{16g/mole}=2.04moles[/tex]
Now for the mole ratio, divide each value of moles by the smallest number of moles calculated.
For C = [tex]\frac{2.04}{2.04}=1[/tex]
For O = [tex]\frac{2.04}{2.04}=1[/tex]
The ratio of C : O = 1 : 1
The mole ratio of the element is represented by subscripts in empirical formula.
The Empirical formula = [tex]C_1O_1[/tex] or, [tex]CO[/tex]
Therefore, the sample is, CO (carbon monoxide)
The sample is carbon monoxide, CO
To obtain the name of the sample, we shall determine the empirical formula of the compound. This can be obtained as follow:
Carbon (C) = 24.50 g
Oxygen (O) = 32.59 g
Empirical formula =? Divide by their molar massC = 24.50 / 12 = 2.04
O = 32.59 / 16 = 2.04
Divide by the smallestC = 2.04 / 2.04 = 1
O = 2.04 / 2.04 = 1
Thus, the empirical formula of the compound is CO.
The name of the CO is carbon monoxide.
Therefore, we can conclude that the sample is carbon monoxide, CO.

What are some problems chemist must consider when developing new technologies?
Final answer:
Chemists must consider economic costs, environmental impact, thermodynamic constraints, and societal demands when developing new technologies. They face challenges in optimization, scalability, safety, and compliance with environmental regulations. Embracing green chemistry practices is increasingly important for sustainable development.
Explanation:
When developing new technologies, chemists must consider a range of complex problems. These include the design and synthesis of new materials, creation of new fuels, fabrics, and foods at low cost, and finding eco-friendly solutions for waste disposal, air and water purification. They must be mindful of the constraints imposed by thermodynamics while meeting society's demands. Additionally, the development of instant drug therapies for diseases is another area of focus.
In the industrial sector, an industrial chemist prioritizes the cost of synthesis and the economic value of the molecules being developed. They strive for economical synthetic procedures that consider not only the cost of the chemicals but also waste treatment and environmental impact. This may involve overcoming challenges in scaling up reactions while ensuring reproducibility, safety, and cost-effectiveness.
Chemical engineers face the challenges of optimizing reaction conditions to avoid side-reactions and ensure high-quality products within pharmaceutical production and other industrial processes. They also deal with the development and design of facilities for chemical manufacturing with consideration for environmental, safety, and consumer welfare.
Finally, the responsibilities of chemists and chemical engineers now extend beyond traditional manufacturing concerns to include regulatory compliance, liability issues, and the incorporation of principles of green chemistry to reduce the use of hazardous materials and minimize environmental impact.

Which methods could you use to calculate the y-coordinate of the midpoint of a vertical line segment with endpoints at (0, 0) and (0, 15)?
One of the most convenient ways of finding or calculating for the midpoint of the line segment is to get the average of the coordinates of the points.
Average of abscissa = (0 + 0) / 2 = 0
Average of ordinate = (0 + 15) / 2 = 7.5
Hence, the midpoint of the line segment is equal to (0, 15/2).
The value of the y-intercept is 15/2.
Answer : The y-coordinate of the midpoint of a vertical line segment is, 7.5
Step by step explanation :
The method used to calculate the y-coordinate of the midpoint of a vertical line segment is, Mid-point formula.
If a line segment AB with endpoints at [tex](x_A,x_B)[/tex] and [tex](y_A,y_B)[/tex]
The mid-point formula will be,
[tex]M=(\frac{x_A+x_B}{2},\frac{y_A+y_B}{2})[/tex]

An experiment requires 42.5 g of sulfuric acid, which is easier to measure by volume than by mass what voliume should be measured out if the denstiy of the sulfuric acid is 1.84
Using proportions,
if x is the unknown volume we have:
1.84 / 1 = 42.5 / x
Multiply both sides above by x:
1.84*x / 1 = 42.5
1.84*x = 42.5
Divide both sides by 1.84:
x = 42.5 / 1.84
X = 23.10 mL
Answer:
The volume of liquid is 23.098 mL.
