HELP !! how can i identefy an unknown metal (I have less than 24h)?
- I can't incinerate the metal
- I can't mix the metal with water
- I can't measure the volume of the metal
There must be a gas reaction !!
I probably have to use some kind of acid and measure the mass before and after the reaction i think.
PLZ HELP ME !! i have to know it in less then 24 houres ! it is very important for my grades.
