Answer:
It's Al 3+ + 3e - → Al
Explanation:
Because three negatively charged electrons are needed to balance the three positive charges on the aluminum ion
Answer:
22.5L
Explanation:
Given parameters:
Volume of N₂O₃ = 15liters
Unknown:
volume of oxygen gas = ?
Solution:
To solve this problem, we need to work from the known to unknown. The known is N₂O₃. We can find the number of moles from here.
Note: The condition is Standard temperature and pressure
Number of moles =
Number of moles of N₂O₃ = = 0.67moles
The equation of the reaction;
2N₂ + 3O₂ → 2N₂O₃
Since the equation is balanced;
2 moles of N₂O₃ is produced from 3 moles of O₂
0.67moles of N₂O₃ is produced from = 1.01 moles of O₂
Therefore;
Volume of O₂ = 1.01 x 22.4 = 22.5L
Answer:
Anaphase
Explanation:
<em>The centromere splits during the anaphase of the cell division. Thus, allowing the two linked chromatids to separate.</em>
A typical chromosome is made up of two sister chromatids joined together by a structure known as the centromere. During cell division - at the metaphase stage - the chromosomes align at the equator of the cell, forming the metaphase plate. The spindle from the opposing ends of the cell engages each chromosome at the kinetochore of the centromere.
<u>At the anaphase stage</u><u>, the centromere splits, leading to the separation of the sister chromatids of each chromosome. The sister chromatids of the same then start migrating in the opposite direction as a result of the shortening of the spindle fiber.</u>
Answer:
Explanation:
Briefly, the scientific process starts by making an observation of a phenomenon, which leads you to question what is happening, and then to formulate a hypothesis.
The hypothesis is a reasonable explanation of the phenomenon, which relates a cause and a consequence, and that can be testable, and can result to be true or false.
Then, you design an experiment to test the hypothesis.
The experiments will give you a set of data which must be interpreted to conclude whether your hypothesis was true or false. This may be seen as the final step of the process, which gives the outcome of the scientific process. This conclusion must be based on reliable data and a logical.
If, your conclusion is clear, logically deducted from the data, using a correct analysis, your experiment was succesful. No matter whether the hypothesis resulted true or false.
Nevertheless, this is not really the final step, as now sharing the information with the scientific community is very important. I t might also happen that you want to iterate the process, to test a new hypothesis.
Instead of f(x) = 89x - 100
It will be
f(x) = 89x + 25
And that is equivalent of shifting the line vertically up by 125 (we move from -100 to 125)
Hope this helps
