Solutions of strontium hydroxide, silver nitrate, hydrogen phosphate, potassium nitrate, and copper (II) sulphate are prepared and placed in separate containers. Consider the reaction of the pairs of these compounds.
a) which pair (or pairs) of these compounds form one insoluble compound and one soluble compound (the soluble compound can not be water) when mixed together? use the chemical reaction(s) to support your answer.
b)which pair (or pairs) of these compounds form two insoluble compounds when mixed together? use the chemical reaction(s) to support your answer.
c)which pair (or pairs) of these compounds form one insoluble compound and water when mixed together? use the chemical reaction(s) to support your answer.
when 50 mL of water containing .5 mol HCL at 22.5 degrees C is mixed with 50.0 mL of water at 25 degrees C in a calorimiter, the temperature of the solution increases to 26 degrees C. How much heat was released by this reaction?
Explain why the boiling point of an aqueous solution that is 1.0 m in glucose (C6H12O6) is 100.51oC whereas The boiling point of an aqueous solution that is 1.0 m in NaCl is 101.02 oC .
V is the volume, and n is a number that can be 1, 2, 3, ... . Assume that A=1. Determine the work done by the piston. Propose a physical meaning to the term "n" in the above equation.
Assume that the wet limestone process requires 1 metric ton of CaCO3 to remove 90% of the sulfer from 4 metric tons of coel containing 2% S. Assume that the sulfur product is CaSO4. Calculate the percentage of the limestone converted to calcium su..
flask apparatus, which now contains 2.00 L H2 at a pressure of 360 torr and 1.00 L N2 at an unknown pressure. if the total pressure in the flasks is 320 torr after the stopcock is opened, determine the initial pressure of N2 in the 1.00-L flask.
