Answer: I believe the 1st and 3rd reactions are better obtained through reference sources and the 2nd and 4th are easiest and safest to measure in the laboratory.
Explanation:
I am also working on this Pre-lab right now, and I looked back at the first question to help get my answer. In the first question (a), it is noted that ammonia gas and gaseous hydrochloric acid are both potentially dangerous in gaseous form. I saw that both the 1st and 3rd reactions contained noxious gases (I knew this because there was a (g) in both of these reactions). Using the knowledge from the first question that the noxious gases were potentially dangerous, I assumed that those reactions were the ones that are better obtained through the reference sources. The 2nd and 4th reactions did not contain any noxious gases, so I assumed those ones were easiest and safest to measure in the laboratory. Hope this helps!
The maximum oxygen uptake is known as the VO2 max.
Answer:
number of moles of
=4.16mol
Explanation:
experiment data:
temperature=
=273+22 k=295k
pressure=1.007 atm
volume is missing so assuming volume-=100L
using ideal law relationship
ideal gas means gas which occupies negligible space and there is no interaction between the molecules of gases.
PV=nRT
put all the experimental data, we get
n=4.15 mol
number of moles of
=4.16mol
Answer:
0.94
Explanation:
Let's assume that the total sample of the soil is 1 cm³; which has a porosity of 0.4 cm³; then the original sample of the soil will be 0.6 cm³
The mass of the soil particles in 1 cm³ of soil + water = 0.75 g
The fraction of the total atrazine can be calculated by the expression;
Total atrazine =
Also; 
NOTE THAT: 
Total atrazine can now be calculated as:
= 


= 0.94
Thus,the fraction of total atrazine that will be adsorbed to the soil = 0.94.
