Answer:
2.05mg Fe/ g sample
Explanation:
In all chemical extractions you lose analyte. Recovery standards are a way to know how many analyte you lose.
In the problem you recover 3.5mg Fe / 1.0101g sample: <em>3.465mg Fe / g sample. </em>As real concentration of the standard is 4.0 mg / g of sample the percent of recovery extraction is:
3.465 / 4×100 = <em>86,6%</em>
As the recovery of your sample was 1.7mg Fe / 0.9582g, the Iron present in your sample is:
1.7mg Fe / 0.9582g sample× (100/86.6) = <em>2.05mg Fe / g sample</em>
<em></em>
I hope it helps!

Answer: Temperature will Increase
PV=nRT. Ideal Gas Law
We see by inspection of the ideal gas law, there is a liner relationship between Pressure and Temperature of an ideal gas. So if the pressure is increased on the gas, then the Temperature will increase also.
Any questions please feel free to ask. Thanks and have a great day!
Because Arsenic is in group 15 it will receive 5 valence electrons Start out by adding one dot around the symbol for Arsenic. You'll end up with 4 around it and <span>all you have to do is add another one.</span>
