Reporting our results allows other scientists to build on our work. It also allows them to repeat our experiment to see if they get the same results. How does this selection contribute to the entire article? A by elaborating on ways that the scientific method has changed B by emphasizing a contrast between different results of the scientific method C by indicating the problems with reporting results of the scientific method D by illustrating the effects of the scientific method for other scientists
Answers
Answer:
D by illustrating the effects of the scientific method for other scientists
Explanation:
Science is a continuum of research efforts. Each new work builds on the results of earlier works. Such earlier works must be reproducible by other scientists who wish to obtain the same results.
Hence, following the scientific method in a scientist's research has an effect on other scientists as they try to reproduce such results obtained in order to advance the frontiers of knowledge.

A sample of unknown concentration is diluted by placing 0.2 mL into 9.8 mL of buffer and then 3 mL is placed into a standard 1x1 cm square cuvette. It is measured at 350 nm and the Abs is 0.3. The molar absorptivity is 12.3 L/mol*cm. What is the concentration of the undiluted sample (mol/L to 2 decimal places)?
Answers
Answer:
The answer is "[tex]4.875 \ \frac{mol}{l}\\[/tex]".
Explanation:
The molar absorptivity value is= 12.3 [tex]\frac {L}{mol \times cm}[/tex]
path length of cell = 1 [tex]\ cm[/tex]
Absorbance = 1.2
Using the beer's lambert law:
[tex]A = \varepsilon \ cl\ \ \ \ \ \ \ _{where} \\\\c= \frac{A}{ \varepsilon l } \\\\[/tex]
[tex]= \frac{1.2}{12.3 \times 1}\\\\= 0.0975 \ \frac{mol}{L}\\[/tex]
Claculating the concentration of the solution after dilution: [tex](m_2)= 0.0975 \ \ \frac{mol}{L}[/tex]
find out the dilution value before concentration :
The volume taken by the dilution: [tex](V_1) = 0.2\ ml[/tex]
The final volume after dilution:
[tex](V_2) = 9.8+0.2\\[/tex]
[tex]= 10 \ ml[/tex]
Formula:
[tex]\bold{M_1 \times V_1 = M_2 \times V_2} \\\\ M_1= \frac{M_2 \times V_2 }{V_1}\\\\[/tex]
[tex]= \frac{ 0.0975 \times 10 }{0.2}\\\\= \frac{ 0.975 }{0.2}\\\\ = 4.875 \ \frac{mol}{l}\\[/tex]

What is an example of reactivity?
A. A piece of paper being torn
B. A nail heating up
C. An ice cube melting
D. A bicycle rusting
Answers
Answer:
D. A bicycle rusting.
Explanation:
A. is incorrect because tearing a piece of paper is a physical change, not a chemical change.
B. is incorrect because we are just heating up the object. That only changes how fast the particles are moving and the change in state of matter.
C. is incorrect because we are adding heat to change a state of matter (from solid to liquid) and it is a physical change.
Therefore, only D. is the correct answer. Iron rusts, and when it does, it chemically changes into an iron oxide (rust).
Answer:
Im pretty sure that it’s D.

ISOTOPES:
Isotopes are atoms of the same element with the same atomic number and chemical identity but different atomic masses. The forms in which atoms of a particular element exists is referred to as its isotope.The sole difference between isotopes of the same element is the number of neutrons each contain, which is responsible for the difference in masses. This means that isotopes of the same element must have the same atomic symbol and number of protons.
