B - A chemist might determine the fat content in a candy bar.
1) Fatty acids stored in candy bars are (in fact) composed of chemical substances.
2) Choice A makes no sense. This activity belongs in the Biology field. Or if you're an animal activist, you might be interested in undertaking this as a hobby.
3) Choice C is absurd because either you're a Physicist who enjoys an occupation such as this, or you're just plain crazy.
4) Choice D is preposterous because either you're a Meteorologist, or a Geoscientist. Both of which have nothing to do with chemistry.
X: 1S²2S²2P⁶
Y: 1S²2S²2P⁶3S²3P⁶
The statement which is most likely correct about the two elements is
They will not react because both have a complete outermost shell and are stable.
<u><em>Explanation</em></u>
The P orbital can hold a maximum of 6 electrons,therefore the 2P orbital for x and 3P orbital for Y which are outermost subshell are fully filled .
This make element Y and x stable since they cannot react either by gaining or losing electrons.
Answer:
Hemoglobin
Explanation:
Hemoglobin is a protein in your body, it carries oxygen to your body and transports carbon dioxide from your organs to your lungs. This is just what i know
Answer:
pH of the solution will slightly increase as it becomes less acidic for which it turns out to be more diluted.
Explanation:
Hello there!
In this case, according to the given information, it turns out possible for us to calculate the pH change of the solution by firstly calculating the HCl concentration, as equal to that of the hydrogen ions whose pH is 2 as this is a strong acid:
![[HCl]=[H^+]=10^{-pH}=10^{-2}=0.01M\\](https://tex.z-dn.net/?f=%5BHCl%5D%3D%5BH%5E%2B%5D%3D10%5E%7B-pH%7D%3D10%5E%7B-2%7D%3D0.01M%5C%5C)
Now, since water is added to the solution, but we do not have the initial volume of this solution, we can ensure that its pH will increase, become less acidic, because the concentration of the acid, and consequently that of the hydrogen ions, is diminished as the volume is increased.
Best regards!
