Heavy water, D2O (molar mass = 20.03 g mol-1), can be separated from ordinary water, H2O (molar mass = 18.01), as a result of the difference in the relative rates of diffusion of the molecules in the gas phase. Calculate the relative rates of diffusion of H2O and D2
A 10 mL sample of a solution of Pb(ClO3)2 was diluted with water to 21 mL. A 10 mL sample of the dilute solution was found to contain 0.021 moles of Pb2+. What was the concentration of Pb(ClO3)2 in the original undiluted solution?
What source of errors can occur if we use the temperature of the room to determine the density of water?
Gaseous indium dihydride is formed from the elements at elevated temperature: In(g)+H2(g) (reactions goes both ways=double arrow) to InH2(g) with Kp=1.48 at 973 K
how do the densities of metals can be calculated? could this method be used for determining the density of mercury as
Would it be possible to vary the temperature of a system consisting of water and ethanol (CH3CH2OH) while maintaining an equilibrium between solid, liquid, and vapor phases?
many biochemical reactions are catalyzed by large protein molecules called enzymes. a typical mechanism for the
What mass of this substance must evaporate in order to freeze 160 g of water initially at 21 0C? (The heat of fusion of water is 334 {J/g}; the specific heat of water is 4.18 {J/g c.K}.)
The total mass of the car plus sand is 85,000 . The hopper door is not fully closed so sand leaks out the bottom. After 18.0 minutes, 1.34×104 of sand has leaked out. Then what is the speed of the railroad car?
Another metal phosphate is nickel phosphate. It will behave similar to calcium phosphate in an acid solution. What is the net ionic equation including phases for NiPO4(s) dissolving in H3O+(aq)?
At room temperature (20 degrees Celsius), milk turns sour in about 64 hours. In a refrigerator (3 C) milk can be stored 3 times as long before it sours. Explain how long should it take milk to sour at 40 C
What common structural features or functional groups allow benzoic acid to physically distribute itself between the two layers in Part A (methylene chloride and water)
A 14.0-g sample of CaCl2 is dissolved in 131 g of water, with both substances at 25.0°C. Calculate the final temperature of the solution assuming no heat lost to the surroundings and assuming the solution has a specific heat capacity of 4.18 J/°C ..
