Answer:
Inert gases or noble gases
Explanation:
These gases have 8 outer shells meaning their full so they won't allow chemical reactions therefore providing an inert environment hence the name inert gas.
Adding perchloric acid to water would cause it's conductivity to increase.
Answer:
Most of the matter around us, however, consists of mixtures of pure substances. Air, wood, rocks and dirt are examples of such mixtures. Mixtures can be further classified as Homogeneous and Heterogeneous.
AgNO3(aq) + KCl (aq)-----> AgCl(s) + KNO3(aq)
Ag ^+(aq) + NO3^-(aq) + K^+ (aq) + cl^- (aq) ----> AgCl(s) + K^+(aq) + NO3^-(aq)
net ionic equation
Ag ^+(aq) + Cl^-(aq) ----> AgCl(s)
