We have to know the product formed on reaction of ethyl iodide with triethylamine.
The product is tetraethylammonium iodide salt.
On reaction of ethyl iodide with triethylamine, a quarternary salt is produced which is ionic in nature. The salt is ionic and polar, it gets dissolved in polar solvent but insoluble in non-polar solvent.
As it is ionic compound, its melting point is high, it does not melt below 200°C.
The structure of the product (tetraethylammonium iodide salt) is shown below:
Converting mmHg to atm is solved by division.
Example: Convert 745.0 to atm.
Solution- divide the mmHg value by the 760.0 mmHg / atm.
745 mmHg over 760.0 mmHg/atm
atm value is 0.980263
Now, I am a medical student and we have never had to convert a BP (blood pressure) to atm from mmHg, only ever kPA. SO, I am going to take a guess here and say that when you do the work to solve this, you are going to convert the Systolic (upper #) which is the 145. You should get 0.190789 and then convert the Diastolic (lower #) which is 65. You should get 0.08552632.
So your fraction so to speak should read, 0.190789/0.08552632 or 0.190789 over 0.08552632
(Just to note that is way to low of a BP, although it is irrelevant) Best wishes and good luck. "Remember, never just look for the right answer, look for why it is the right answer!"
<span>a. 0.325 g / 63.55 g/mol = 5.11 X 10^-3 moles Cu. SHould form 5.11 X 10^-3 mol Cu2+
b. Should form 5.11 X 10^-3 mol Cu(OH)2
c. 1 g Zn / 65.4 g/mol = 0.0153 mol Zn
Excess Zn = 0.0153 - 0.0051 = 0.0102 moles excess zinc
d. 5.11 X 10^-3 mol Mg X 24.3 g/mol = 0.124 grams Mg</span>
<span>The answer to this would be radioactive decay. This is also known as "nuclear decay" or "radioactivity".</span>
I’m pretty sure it would be:
NH4+Cn
