Answer:
See explanation
Explanation:
The melting point range of a pure compound is about 1-2ºC of the expected melting point. An impure solid melts within a range that is both larger than that of the pure substance (>1ºC) and begin at a lower temperature because impurities decrease the meting point. A melting range of 5º or more indicates that a compound is impure.
Since the melting points of A and B are estimated at 133 o C, the melting point range for each pure substance must be slightly different from each other. The melting point of the unknown is measured and its range is compared with the melting point ranges of pure A and B then decision can now be made about the identity of the unknown solid.
An atom is the basic unit of all matter. The other answers are just pieces of an atom
Answer:
The systematic name of the complex is: ![[Cu(en)_2(H_2O)_2]I_2](https://tex.z-dn.net/?f=%5BCu%28en%29_2%28H_2O%29_2%5DI_2)
diaquabisethylenediaminecopper(II) iodide
Explanation:
= Given complex whose naming is to be done:
Rules for naming of the coordination compounds :
- The name of ligand should be written first and then metal.
- The charge of metal indicated with the Roman numerals and enclosed in the parenthesis after metal name.
- The ligand's names written should be in an alphabetical order before the metal ion.
- Ligands that include a numerical prefix in the name use the prefixes bis or dia for 2, tris for 3, or tetrakis for 4 to indicate their number.
- If the complex ion is an anion, we drop the ending of the metal name and add –ate.
The cationic part of the complex: diaquabisethylenediamine copper(II)
The anionic part of the complex: iodide
The systematic name of the complex is:
diaquabisethylenediaminecopper(II) iodide

if it is edible you can taste it if it taste bitter its a base and if it taste sour then it is a acid if it taste like nothing like water would it would be a neutral substance.you could also order a ph tester which is just a liquid that you drop in it.
