If a small amount of water is added to liquid HN3, in this solution water will act as an a) Acid; b) Base; c) Inert substance; d) Solvent;
Water is weaker acid than HN3, and it will react as a base.
Rank the basicity of salts: KCN ,NaOCl,Na2S
KCN > NaOCl>Na2S; The greater the pKa value, the more basic the salt is.

How the product yield changes if volume of a system BaCO3 = BaO+CO2 is doubled?
Increasing the volume, decreases the pressure. It is equivalent to decreasing concentration of CO2 which shifts reaction to the products.
needs and Neil will reply soon.
