A. Identify the steps of the scientific method?

Chemistry
1 answer:
DedPeter [7]3 years ago
4 0

Answer:

1. The steps of the scientific method consist of seven things: Ask a question, get the research needed for a experiment, (What are you trying to find out? What materials do I need to complete the experiment? What are the procedures needed to complete the experiment?) create a hypothesis, (your educated guess on what you think the results of the experiment will be) conduct a experiment (complete multiple different trials preferably three) to test your hypothesis, make observations and record data during the experiment, draw a conclusion, (Was your hypothesis correct? Yes or no and explain why it is wrong or right) present your findings.

2. A hypothesis is a educated guess that the scientist believe will be the answer at the end of the experiment which is why they conduct a experiment in the first place to find viable data that will support their hypothesis.

3.  Predictions consist of theories that will test the hypothesis (educated guess) because they're the reasoning to why you believe your guess is correct.

4. A control group consists of variables that do not go through change during a experiment, things that remain the same.

5. Data can be presented in many different ways in the form of graphs, charts, or a research paper. You find the data by completing multiple different trials in a experiment, to make sure you have valid results to write down in your data research.

6. Remember that your hypothesis is your educated guess at the beginning of the experiment, what YOU thought was going to happen during the experiment and if the data you received during the experiment supports your hypothesis.

7. Your procedures, perhaps you measured a variable wrong, perhaps you used to much, or to little of a variable, all depends on your experiment.

8. Having people review and test your data by conducting their own experiments will not only make sure that your data is valid but it insures you even more of your conclusion, making it more accepted by other scientists.

Hope this helps.

how many moles of hydrogen are evolved when an excess of sodium metal is added to one mole of citric acid?
vova2212 [387]
The formula of citric acid is:

           CO2H
           |
HO -  C - CH2CO2H
          
|
          C - CH2 CO2H



I bolded the 4 hydrogens that can be subsituted by sodium.


Three of those hydrogens belong to carboxyl group (- CO2H) and one to a hydroxyl group (- OH).


You need to take into account that 4 H will form 2 H2 molecules.


So, the answer is that 2 moles of molecules will be formed from 1 mole of citric acid molecules.

Calculate the mass, in grams, of 0.245 moles of nickel(11) perchlorate
Ierofanga [76]

Answer:

38.7 g

Explanation:

first you find the molar mass of Nickle(II) Perchlorate

Nickle = 58.693 g/mol

Perchlorate is Chlorine and Oxygen combined

Molar mass of chlorine is 35.453 g/mol

Oxygen = 15.999 g/mol but since it has 4 oxygen atoms combined with chlorine you have to multiply 15.999 by 4 which is 63.996 add all the masses together and that gives you 158.142. Since you have moles you multiply the moles by the molar mass which looks like this. 0.245 * 158.142 which equals 38.74479 but with sign figs it is 38.7g as your final answer. Ask me if you are confused about something.
