How many liters of the antifreeze ethylene glycol [CH2(OH)CH2(OH)] would you add to a car radiator containing 6.50L of water if the coldest winter temperature in your area is -20 degree celsius? Calculate the boiling point of this water- ethylene glycol mixture. ( The density of ethylene glycol is 1.11g/mL)
what mass of glucose 180.0 gm must be added to 0.50 kg of water to increase the boiling point of the solution by 2.0
Calcium carbonate is a major contributor to the "hardness" of water.
In this reaction, we are actually measuring the rate of formation of the carbocation intermediate. It would be possible for the carbocation to proceed to a product other than the alcohol discussed in the Experimental writeup without changing out k..
Magnesium can be obtained by precipitating Mg^2+ as Mg(OH)2(s). The Ksp of Mg(OH)2 is 6.0*10^-10. The magnesium ion concentration is 0.059M. If a sample of solution is treated so its [OH-] concentration is maintained at 2.0*10^-3M. What will be [M..
An additional atm pressure of HI is admitted to the con- tainer, and it is allowed to come to equilib- rium again. What is the new partial pressure of HI?
Metallic aluminum reacts with MnO_2 at elevated temperatures to form manganese metal and aluminum oxide. A mixture of the two reactants is 67.2% mole percent Al.
sodium sulfate how many grams of solid ppt will be formed. How many grams of reactant in excess will remain. What is chemical equation
Carbon dioxide makes up approximately 0.04% of the Earth's atmosphere. If you collect a 2.0L sample from the atmosphere at sea level (1.00 atm) on a warm day
The conductance of an aqueous solution of trans-[Co(en)2Cl2]Cl changes on standing overnight. Would you expect it to incease or decrease. Why
