Repetition is repeating the same investigation over and over again . Such as you doing an experiment and redoing to to see if you get the same results however it is often confused with replication . Replication is when you copy an experiment done by someone else . Such as seeing an experiment and trying to get the same results as someone . Repetition you often do yourself while replication you copy someone else .
2. What procedure did you use to complete the lab?
Outline the steps of the procedure in full sentences.
Section II: Observations and Conclusions
3. What charts, tables, or drawings would clearly show what you have learned in this lab?
Each chart, table, or drawing should have the following items:
a. An appropriate title
b. Appropriate labels
4. If you could repeat the lab and make it better, what would you do differently and why?
There are always ways that labs can be improved. Now that you are a veteran of this lab and have experience with the procedure, offer some advice to the next scientist about what you suggest and why. Your answer should be at least two to three sentences in length.
Writing the Lab Report
Now you will use your answers from the four questions above to write your lab report. Follow the directions below.
Section I: Overview of Lab
Use your answers from questions 1 and 2 (above) as the basis for the first section of your lab report. This section provides your reader with background information about why you conducted this lab and how it was completed. It should be one to two paragraphs in length.
Section II: Observations and Conclusions
Use your answers from questions 3 and 4 (above) as the basis for the second section of your lab report. This section provides your reader with charts, tables, or drawings from the lab. You also need to incorporate your answers to the follow-up questions (from the Student Guide) in your conclusions.
<u><em>Answer:</em></u>
2 H₂O ............> 2 H₂ + O₂
<u><em>Explanation:</em></u>
<u>To balance a chemical equation,</u> we need to make sure that the number of moles of each element on the reactants side is equal to the number of moles of that elements on the products side.
<u>For the given equation:</u>
H₂O ............> H₂ + O₂
<u>We need to make sure that:</u>
number of moles of reacting hydrogen = number of moles of produced hydrogen
number of moles of reacting oxygen = number of moles of produced oxygen
<u>1- Let's check the Oxygen:</u>
On the reactant side, we have one mole of oxygen
On the products side, we have two moles of oxygen
To balance this, we can multiply the reactants side by 2.
<u>This will give us:</u>
2 H₂O ............> H₂ + O₂
<u>2- Let's check the Hydrogen:</u>
From part 1, we reached the following equation:
2 H₂O ............> H₂ + O₂
From this equation, we can note that:
On the reactant side, we have 2*2 = 4 moles of hydrogen
On the products side, we have 2 moles of hydrogen
To balance this, we can multiply the hydrogen in the products side by 2
<u>This will give us:</u>
2 H₂O ............> 2 H₂ + O₂
<u>3- Let's check:</u>
The equation we reached in part 2 is:
2 H₂O ............> 2 H₂ + O₂
Checking this equation, we can find that:
We have 2*2 = 4 hydrogen moles on reactants side and 2*2 = 4 hydrogen moles on products side
We have 2 oxygen moles on reactants side and 2 oxygen moles on products side
<u>Therefore,</u>
The equation is balanced
Hope this helps :)
Steel is an alloy that is mainly comprised of CARBON. Hope this helps and give thanks plsss!
The +17 is referring to the number of protons within the atom. The minus signs with circles around them represent electrons orbiting the nucleus.
