Many copper salts are blue in solution, and I suspect that's what you're thinking of, but it's not by any means the only element that can be blue. Chromium, vanadium, and magnesium can, in certain oxidation states, be bluish, as can some nickel complexes.
Arsenic, selenium, indium, copper halides ok
Copper.
its not D. none of the above
Ionic compounds produce electrolytes; covalent compounds not.
alkali metal + oxygen --> metal oxide metal oxide + water--> metal hydroxide metal hydroxides are strong alkalis, corrosive pH=14
As a Christian I feel that this question is very offensive.
Chemical elements are combined to produce chemical compounds.
its not D. none of the above
Ferrous
Concentration
Some bacteria absorb copper compounds. They then produce solutions called leachates, which contain copper compounds. This method of extraction is called bioleaching.
no,DissociationWhen ionic compounds dissolve to produce ions the process is typically called dissociation.IonizationWhen molecular compounds dissolve in water to produce ions the process is typically called ionization.
Ionic compounds produce electrolytes; covalent compounds not.
Sodium is a metallic element, it produces no other things by itself. However it is very reactive with many other elements or compounds.
alkali metal + oxygen --> metal oxide metal oxide + water--> metal hydroxide metal hydroxides are strong alkalis, corrosive pH=14
Substances that form ions when dissolved in water are electrolytes.
BASES....BASES...Are Compounds That Produce Hydroxide ions (OH-)....

Yes, in part: The method described in the question is the only way in which compounds can be formed directly from the elements of which the compounds are composed. However, a compound and an element can also react to produce another element, as in Zn + 2 HCl -> ZnCl2 + H2.
