How could you test an unknown compound to determine if it was ionic or covalent?
Conductivity is the easiest way. Ionic compounds conduct electricity in water
What experimental evidence about a new compound must be known before its formula can be determined?
In a laboratory the mysterious compound is initially weighted and then will undergo reactions to be broken down into its constitutes. The individual elements or other compounds will be determined and then be weighed. Using information known on those elements and compounds, scientist will be able to discover the molar mass for each of them. Using the equation n = m/ M (mols = mass over (divided by) molar mass) they are able to determine the moles for each of the elements/compound. the unknown compound will be determined by the product with the lowest number of moles (closest to zero) have its number dividing all the other products (see it as for each mole of that element/compound there will be a requirement of N amount of moles from the other product(s)). This result will give the ratios for the constitutes in the unknown compound (the subscripts). This formula here will be the empirical formula (which may not be the actually formula for the reaction, it is the simplest ratio). Let the unknown compound be X. A and B are the resulting constitutes of X. After determining the correct mols of A and B where B moles is closest to 0, we divide Amols by Bmols and the resulting number is near a whole number. This number will be the subscript for A and will determine the empirical formula of X. If Bmols = 1 and Amols = 2 the unknown compound will have the empirical formula of A2B.

How is an unknown oxidation state of an element within a compound?
It is determined from known oxidation states of other elements.
How is an unknown oxidation state of an element within a compound determined?
It is determined from known oxidation states of other elements.
An unknown compound dissolves in water but the solution does not conduct electricity?
If a compound dissolves into water and allows for the conductance of electrical current its said to be ionic and an electrolyte. Sodium chloride (NaCl) or table salt exhibits this property. Sugar is a compound that will dissolve in water but not conduct current. Sugar is not an electrolyte or ionic; rather a covalent molecule.
Is unknown a compound word?
no
Why did mendeleev had gaps in his tables?
Because during his time many elements were unknown. Hence the gap for the unknown elements.
Are more than 100 elements are currently unknown?
The unknown elements are... well, unknown. However, it seems unlikely that there are 100 elements in addition to the known elements, for stability reasons: in generalm terms, the heavier the nucleus, the more unstable it becomes.
How is an unknown oxidation state of an element within a compoud determined?
In a compound the sum of oxidation states of the elements contained is zero.E1 + E2 + ... = 0If you know the oxidation states of the elements E1... you can calculate the oxidation state of the element E2.
