I feel like this is something I should already know, but I don’t even know what to search for to find an explanation. Solid pure metals like piece of Iron, Copper, or Nickel are made up of atoms all the same (Cu, Fe, or Ni). Each atom has a positive nucleus surrounded by a field of...

A solution is found to have varying quantities of silver, barium and iron (III) ions. Suggest a procedure for seperating the ions by precipitation. Ok ...silver is +1, barium is +2, and iron (III) is +3... so I would have to add anions of the same value (but negative) to the solution in...

A 38.0 g copper ring has a diameter of 2.54000 cm at its temperature of 0°C. An aluminum sphere has a diameter of 2.54508 cm at its temperature of 108°C. The sphere is placed on top of the ring as in the figure, and the two are allowed to come to thermal equilibrium, with no heat lost to the...

Hey guys, i just have some quick questions I'm having trouble with. I'm in a hurry right now so i'll come back tommorow and type up what I was thinking about them, here are the questions. 1) Farmers use ferilizers mainly to replace depleted nutrients in the soil. Liquid ammnia and ammonium...

Hi, just looking into metals and came across silver copper alloy having a density of 9900 - 1.05e4 kg per cubic metre. I have been told me that the value of e is (probably quite randomly) 2.71 and others said that it is an abbreviation for 0, eg. 1,000,000 could be written as 1e6 or 10,000 as...

Can someone explain the concept of recrystallization in metals to me? I'm having some trouble understanding what actually happens in the material during this process, and also what causes it to happen...

would anyone have links why metals generally exist as ores in the Earth's crust, and not as pure metals? I've googled it, nothing popped up. I've checked my textbook, nothing. Why do they ask questions you can't answer. Thanks guys for all your help AEK

Our lecture on the Physics of Solid State raised a question. Professor postulated that the condition of the existence of metals is "Debay radius<Bohr radius", but the explanation was quite unclear. Could someone help me?

Chloroform is said to react violently with both metals (Al, Na, Li, Mg, K, Fe, Zn) and e.g. sodium methoxide (CH3ONa). Does anyone know more about this? What happens? Formation of e.g. CCl3Na with release of H2? Or CHCl2Na+NaCl? And how about reaction with alkoxides? Does chloroform react...

If someday we discover how to mine metals from the core, will it have any effect on the magnetic field or the climate of the Earth due to reduction of heat in the core as the metal mined will be hot and will slowly drain the heat of the core.

What about the molecules and bonds of transition metals make them (such as gold) such good conductors? I'm in AP chemistry, so we may have gone over it, but I don't know right now.

"Rusty metal is a favourite place for C. tetani to hang out, and in fact puncture wounds with rusty nails are a common cause of tetanus." We all know this, but why is that, why C. tetani has this affection fot rusty metals ? C. tetani is anaerobe, and I wonder does this living in iron oxide...

I'm writing some high school physics teaching animations and I need to make sure I have the right idea for why increasing the temperature of a metal increases its resistance. It's high school, so I need some classical analogy which isn't just blatantly wrong or stupid. The explanations I...

metals: physical properties - chemical properties - nonmetals: physical properties - chemical properties - i will be very thankful to anyone who fill up this table and explain the difference between chemical and physical properties and another thing.. i...

why can certain metals be magnetised but others like copper cannot? what what is the difference between permanent magnet and temporary magnets?

Hey, can anyone direct me to information on the role of the following metals in living systems? If you can, please state specific effects and reccomendations of importance(in the body). Zn, Mg, Fe

Can any1 explain this process and why it supposedly only works on metals.

Hello all ... Please , I won't ANY information about this issue . Please help me , I have to finish this today
