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.
Write balanced chemical equations and net ionic equations of KOH reacting with the following compounds (a) (NH4)2SO4, the reaction mixture is heated
consider a major oil spill in a lake ( a prototype situation related to Alaska Oil Spill few years ago and many subsequent spills) Amount of oil spilled is 2.9 mega gram (Mg).
A fixed quantity of gas at 24 C exhibits a pressure of 745 torr and occupies a volume of 4.40 L. Use Boyle's law to calculate the volume the gas will occupy if the pressure is increased to 1.88 atm while the temperature is held constant.
The normal boiling and freezing points of substance X are 87.3 K and 84.0 K respectively. The triple point is at 82.7 K and 0.68 atmosphere. a. Draw a phase diagram for substance X. Label the regions in which the s,l, and g phases are stable.
