Explain what is meant by the scientific method.

Chemistry
1 answer:
VashaNatasha [74]3 years ago
3 0

Explanation:

Scientific method basically minimizes the bias and prejudice in the experimenter. It provides an standardized approach for an experiment. It is a logical approach to seek knowledge that involves forming and testing a hypothesis. There is not a single way to list the steps in scientific method, but the ultimate goal is to gather data that will check the validity of an experiment.

What is the concentration of a 1:10 dilution of a 2.5 M solution of NaCl? How would you prepare exactly 100 ml of such a solutio
Marina CMI [18]

<u>Answer:</u> The concentration of the solution is 0.25 M

<u>Explanation:</u>

Let the volume of solution of 2.5 M NaCl be 10 mL

We are given:

Dilution ratio = 1 : 10

So, the solution prepared will have a volume of = \frac{10}{1}\times 1000=100mL

To calculate the molarity of the diluted solution, we use the equation:

M_1V_1=M_2V_2

where,

M_1\text{ and }V_1 are the molarity and volume of the concentrated NaCl solution

M_2\text{ and }V_2 are the molarity and volume of diluted NaCl solution

We are given:

M_1=2.5M\\V_1=10mL\\M_2=?M\\V_2=100mL

Putting values in above equation, we get:

2.5\times 10=M_2\times 100\\\\M_2=\frac{2.5\times 10}{100}=0.25M

Hence, the concentration of the solution is 0.25 M

Read the scenario and then answer the question.
Dvinal [7]

Elias could be standing on the transform boundary.

Answer: Option 1.

<u>Explanation:</u>

Transform boundaries are places where plates slide sideways past one another. At change limits lithosphere is neither made nor devastated. Many change limits are found on the ocean bottom, where they associate fragments of veering mid-sea edges. California's San Andreas issue is a transform boundary.

Transform boundaries are regions where the Earth's plates move past one another, scouring along the edges. Every one of these three sorts of plate limit has its own specific kind of flaw (or break) along which movement happens. Transforms are strike-slip issues. There is no vertical movement—just horizontal.
