Precipitation, visible-evidenced redox reactions and complexation reactions are used to identify metals.
Explanation:
Hello,
In this case, since you are talking about qualitative analysis, several techniques such as precipitation, visible-evidenced redox reactions and complexation reactions are suitable to identify metals. Such reactions are good enough as long as depending on the metals' cation, it precipitate, redox behavior and complexation will produce a particular color that will allow the identification of the metal.
For instance, to determine the presence of silver, a white precipitate is obtained when chloride ions are placed into a silver-containing sample. The presence of cobalt is substantiated via the formation of a yellowish-brown ionic complex of hexamminecobaltae (II).
<span>Figure out the density. every metal has it's own. just fill a glass up to the top with water, and then carefully put the metal in. measure how much water is displaced (either by collecting the water or by measuring the glass afterwards), then you will have the substance's density, because you have volume and it's measurement. </span>
This is an example of Charles’ Law problems, the basic equation is: V1/T1 = V2/T2. One vital thing to recall for all gas law problems is that the temperature must be in Kelvin (not Celsius). So our given is 10.0 C = 283 K. So V1/T1 = V2/T2 733/283 = 950/T2
