The diffusion coefficient of valine in water at 298 KKis 0.831×10−9m2⋅s−10.831×10−9m2⋅s−1. Determine the time it will take a valine molecule on average to diffuse an rms distance of 2.00. If the molecular diameter of valine is taken to be 0.300 nmnm, what is the time per random walk step?
In measuring the surface tension of a liquid (drop weight method), 20 drops of the liquid (r=0.2cm) falling apart from the tip whose diameter is 0.4cm were found to weigh 0.95 gram. What is he surface tension of the liquid? Show complete solution, and round the final answer up to 4 decimal places.

Nitroglycerine ( C3H5N3O9) is a very strong explosive that degrades over time and is too shock sensitive to transport safely. Dynamite is made by combining nitroglycerine with stabilizers and adsorbents, which makes it much safer to use. The explosion of nitroglycerin can be represented by: 4C3H5N3O9(l)→6N2(g)+12CO(g)+10H2O(g)+7O2(g) A stick of 40% dynamite is about 20 cm long and about 3 cm in diameter and weighs 203 grams. It is 40.0% nitroglycerine by mass. What is the total number of moles of gas produced when a stick of 40% dynamite explodes?
A small crystal of potassium permanganate (orange) and methylene blue (blue crystal) are placed on top of an agar medium in a petri dish. The agar is similar in consistency to gelatin. After one hour, each crystal has diffused away from the center of the dish. The permanganate shows a greater diffusion than methylene blue. The molecular weight of KMnO4 is 158.037 grams per mole, and the methylene blue molecular weight is 319.85 grams per mol. 1. Why did the KMnO4 diffuse faster than the methylene blue crystal? 2. If the plate were cooler, would it change which crystal would diffuse faster? Why
