Hi!

Question

I'm in chem class and I don't know the answer to these questions

I have several metal alloys and have to tell their general elements that make them up

for example
bronze - copper and tin

What is the elements that make up Pewter?

Also I was woundering if someone can tell me

What is an example of solution with a gaseous solute and a solid solvent?

I have no idea...

Also
two methods that increase the dissolving rates of gasses in liquids????????

My teacher wrote some stuff on the board with a whole bunch of arrows that looked like this

G in L
(Arrow Up)Heat, Solubility (Arrow Down), Dissoving Rate (Arrow Down), (Arrow Up) Pressure, Solubility (Arrow Up), Stiring Rate (Arrow Up)

All of the arrows pointing up or down show an increasae or decrease. I think I'm suppose to say something like increase this or decrease this to increase dissolving rate...

my only problem is that dissolving rate is pointing down so I'm lost my teacher dosen't really expect that much sense it's only public high school chemistry =_= basically waste your time taking intro to chemistry because they don't want students taking AP chemistry wihout any background at all...

Answer 1

A site for the components of pewter.
http://en.wikipedia.org/wiki/Pewter

For a gaseous solute and a solid solvent, what about hydrogen gas dissolved in platinum metal?

The others I'll leave as they are since they don't make sense to me. Perhaps another tutor can help. By the way, chemistry can be very interesting if you give it a chance. For example, I've made a very good living with chemistry.

Answer 2

exactly it dosne't make any senst at all lol...

thanks for the help

see it's just public high school chemistry... Let's put it this way after taking AP World history just regular public high school chem seems like a waste of time... What we do in two weeks in that class AP Chemistry does in one day no joke...

Answer 3

I think in order to answer the dissolving rates I need to know the formulas to find dissolving rate not just some arrows and stuff thata leaves me just knowing what happens but knowing why lol stupid publich high school

Answer 4

Don't paint all public high schools with the same broad brush. Some, in fact I think most of them, are good.
