N-Methyl-2-pyrrolidone is an aprotic solvent used in many industrial processes. Draw the structure of the product formed when it is heated with strong aqueous acid 6MHCI, H20 and heat.
A flask contains 0.350 grams of liquid Br( bromine). calculate the number of (Br)bromine molecules present in the flask
What volume of 0.300 M CaCl2 is needed to prepare 240. mL of a solution which is 0.100 M in chloride ion.
When a 3.25 g sample of solid sodium hydroxide was dissolved in a calorimeter in 100.0 g of water, the temperature rose from 23.9 °C to 32.0 °C. Calculate ?H (in kJ/mol) for the solution process: NaOH (s) → Na+ (aq) + OH- (aq)
A groundwater sample is taken from a geologic formation containing various carbonate minerals (e.g., CaCO3, MgCO3, CaCO3•MgCO3, etc.) without exposing the water sample to the atmosphere.
Metallic elements tend to act as Lewis acids and form complexes with a variety of Lewis bases. Since most elements are metals, and almost all metals form complexes, it is important to understand these complexes
