I'm just disillusioned by the obvious manipulation that's going on here.

Density of Al = 2.70 g/cm^3 (1 cm^3 = 1 mL) density = mass/volume <=> volume = mass/density So, for 10,000 g of Al v = (10000 g)/(2.70 g/cm^3) = 3704 cm^3 (i.e. 3.7 L) For a sphere: Volume of a sphere = 4/3 x x r^3 <=> r = (3V/4)^(1/3) So, for a volume of 3704 cm^3; r = ((3x(3704...

Ladies and gentlemen, we have sub USD 19.00 silver - 18.98.

Guys - wow. USD 19.11 AUD = 0.9272 USD

Here's a video that shows exactly how Tollen's reagent (diamminesilver(I)) is made and subsequently reduced with glucose to produce the beautiful 'silver mirror' effect. The Tollen's test - developed by a German chemist of the same name - was actually used as a diagnostic test for...

They require that the first year's lease is paid in one payment, then they will allow monthly payments for subsequent years. I also second the sentiments above - Guardian Vaults are first rate and I'd highly recommend them.

This is certainly the case at ABC in Sydney.

Any time you're diluting a concentrated acid, you should always slowly add the acid to the water. "Do as you oughtta, add acid to water." This is because the reaction between water and a strong acid (they actually react when you mix them) is quite exothermic. Adding a small amount of water to a...

Yes, that brown gas is nitrogen dioxide. It is produced via thermal decomposition of nitric acid, so a more vigorous reaction (more heat) will increase the rate at which the acid decomposes, meaning that some of it is wasted and only making the whole process more dangerous. It hydrolyses (i.e...

I've considered trying this out just for the fun of it. As others have said, you can certainly get nitric acid. Definitely do be careful with it, though. I don't want to sound like I'm saying not to do it - I'm definitely not saying that and I think that anybody who wants to be able to do...

I think matte is probably best, yes.

I think a black background also helps a lot. Any plain background would be better than a non-plain background, but I think black 'brings out' the silver the most.

It actually seems (mostly) fairly clear to me. Your quote mentions only coins of gold, silver and platinum... "coins of gold, silver and platinum [...]. These coins...". I think it's pretty clear that it refers only to gold, silver and platinum coins for the purposes of being exempt from import...

At the end of the day, silver, along with just about everything else that can be sold or traded, only has value because enough people agree that it does. Silver may have industrial applications, but, even so - it is only 'valuable' for those uses because enough people agree that it is worth...

Yep. It's all totally rigged. Manipulated down; manipulated up. :Iprobablyshouldwhipoutmysarcasmsmileyherejustincase:
