Answer:
d. 114.8 u
Explanation:
The formula for the calculation of the average atomic mass is:
Given that:
<u>For first isotope:
</u>
% = 95.72 %
Mass = 114.9041 u
<u>
For second isotope:
</u>
Since the element has only 2 isotopes, so the percentage of second is 100 - first percentage.
% = 100 % - 95.72 % = 4.28 %
Mass = 112.9043 u
Average Mass = ?
Thus,
<u>Average atomic mass = 114.8 u</u>
Oh, cool! I'm learning this too!
This may sound difficult, so let's try a example of one now. How about Boron?
(*hiya, mr.boron! (^u^/)*)
The ATOMIC NUMBER is located at the very top of the group symbol you're referring to.
"So how do I locate it?"
_______________
| 5 | <======Atomic # | B | <====== Symbol
| Boron | <=== Element Name
10.81 <====== Atomic Mass |______________|
In this case, the number is five, which is representing 5 atoms with protons and electrons. It does not have 5 single protons or electrons, otherwise it'd be one group of positive protons, negative electrons, and so on.
Try not to get it confused by ATOMIC MASS, which is located on the bottom (10.81; That could appear as a trick question on a quiz of some sort. It happened to me once, yikes.) The Atomic Mass contains the number of protons and NEUTRONS (The center nucleus of the atom), which contains nada, zero, nothing. It has ABSOLUTELY no charge, at all.
Hope that worked! :)
Answer:
The red balloons have a biconcave disk structure, which is what is worded in the question seems to me a little wrong.
On the other hand, the elongated structure of muscle cells is due to a greater initial length in order to perform muscle contractions in a better way, or to perform their function at sea.
Something very important that the differences is that the red balloon does not have a nucleus (the muscle cell is multinucleated and has more mitochondrial load) and this structure is characteristic for being able to transport gases such as oxygen and disseminate them better in the body.
Explanation:
Red blood cells also have a shorter half-life than muscle cells, they are responsible for traveling throughout the body and renew their hemoglobin component after 120 days in the spleen.
On the other hand it is important to note that both work together when performing physical exercise, one donates oxygen and the other consumes it, considering that the muscle cell has more capacity to withstand hypoxic moments, that is why it supports lactic fermentations in anaerobic processes .
In summary, the red globule has this shape to act as gas transport, and the muscle cell to have a better start in contractile function.
Answer:
the answer is B-2nd; stars
Explanation:
When Salt is dissolved into a water solvent; Yes, it can be extracted through evaporation. It retains its original properties: Choice C.
The salt when dissolved in water solvent forms a solution.
They can be separated by boiling the mixture.
The solution formed is a mixture which can be separated by evaporation of water molecules do that the salt is left in the heating chamber.
