How To:Extract DNA from a Strawberry with Basic Kitchen Items ByGabrielle Taylor 11/17/2012 9:37 am Science Experiments We all know that DNA is pretty amazing, but it's not something that most of us get much hands-on experience with. Even though it's in every living thing around us,...
We can calculate the moles of HCl in the first question. We have 80 ml of 1.75M HCl solution. Molar is defined as moles/liter. We'll convert 80ml to liters and then multiply by 1.75 moles/liter to find moles HCl. (1.75moles/liter)*(0.08 liters) = 0.14 moles HCl. We need to ...
Question: A 75.0 mL sample of 1.48×10−2M Na2SO4(aq) is added to 75.0 mL of 1.24×10−2M Ca(NO3)2(aq) What percentage of the Ca2+remains unprecipitated? (Ksp = 9.1x10-6) I tried solving for [Ca2+] using Ksp and then divided moles of Ca2+ in the solution by # of origi...
Aluminum alloys play an important role in circular metallurgy due to their good recyclability and 95% energy gain when made from scrap. Their low density and high strength translate linearly to lower greenhouse gas emissions in transportation, and their
Deep-sea dragonfish are found in the deep seas, so scientists rarely get the time to study them in-depth. Also known as the shiny loosejaw, they've been spotted off the west coast of the U.S. and Canada, with sightings from as far north as British Columbia and down to Baja, Mexico...
In fact, Ag-side Si atom when the the dOi2stmanocleecwuales moved horizontally as if it experienced decreased to ~2.6 Å. This indicates that a repulsive force from the the reactivity with oxygen is quite different between the outer- and Ag- side Si atoms, which would come from ...
What is the strength of the stuff you would normally buy at a store? Its no 38.5%.. is 38.5% a "big" number in this context? how would I determine the molarity of this solution I have made? I cant thank you guys enough for the help, and tolerance to my chemistry n00bness...
Besides giving a more visible explanation of his known theoretical approach (nature is the origin of everything, in a nut shell), the illustration, featuring Architecture as goddess seated on the ruins of a destroyed building showing a primitive hut to the genius of reason (a cupid), talks ...
skin, the consequences to skin-related biological processes and, based on such knowledge, we suggest some therapeutic targets. We also explored the recent advances regarding the molecular clock disruption in melanoma, its impact on the carcinogenic process, and its therapeutic value in melanoma ...
How to find amount of water needed in dilution?What volume of 0.75M potassium hydroxide solution is needed to make 350 mL of a 0.15 M solution? Approximately what volume of water is also needed? I got a volume of 70. mL KOH, but how do I find the volume of water needed?
