<span>Conductance gives a more accurate method to determine the salt concentration of a solution.Conductivity would be used with conductors such as metals that include copper and silver.Conductivity is a measure of water's capability to pass electrical flow. This ability is directly related to the concentration of ions in the water. These conductive ions come from dissolved salts and inorganic materials such as alkalis, chlorides, sulfides and carbonate compounds</span>
Valence electrons determine its valency ? (The group, as in its oxidation state and stability)
3.18 grams of product (Cu I) - 2.54 grams of Cu (reactant) = .64 grams of Sulfur, by law of conservation of mass.
Answer:
ethane=c2h6
ethyne=c2h2
ethene=c2h6
Explanation:
ethane has single bond between carbon atoms(it is alkane.) ethyne has triple bond between carbon atoms(it is alkyne) ethene has double bond between carbon atoms (it is alkene)
