How much heat is evolved when 1241 g of water condenses to a liquid at 100.°C?
Assume that the heat was completely absorbed by the water and no heat was absorbed by the reaction container or the calorimeter or lost to the surroundings. Calculate the Hrxn per mole of SiH4.
A solution may contain the following ions Ag+, Cu2+, Cd2+, Mn2+, Ni2+ and Na+. A white precipitate formed when 0.10 M NaCl was added and after this was removed the solution was treated with H2S gas under acidic conditions and no precipitate formed..
One hundred grams of water is saturated with NH4Cl at 50 degrees celsius . According to Table G, if the temperature is lowered to 10 degrees celsius, what is the total amount of NH4Cl that will precipitate.
The following show the connectivity of atom only atom other than carbon and hydrogen are labeled how many degree of unsaturation are pressent in the compound? chose the correct answer from the following.
In a coffee-cup calorimeter, 1.50 g of NH4NO3 is mixed with 76.0 g of water at an initial temperature of 25.00°C. After dissolution of the salt, the final temperature of the calorimeter contents is 23.65°C.
Calculate empirical formula of this compound & molecular formula and calculate the molality of solution of sulfuric acid?
A graduated cylinder contains 18.0 m/L of water. What is the new water level after 35.6 g of silver metal with a density of 10.5 g/mL,is submerged in the water?
Account for the fact that H3C-Cl (dipole moment 1.94D) and H3C-F (dipole moment 1.82D) have almost identical dipole moments, even though fluorine is considerably more electronegative than chlorine.
A solution contains 2.0×10-4 M Ag+ and 3.6×10-2 M CO32-. Determine Qsp for Ag2CO3. Will Ag2CO3(s) precipitate? [Ksp for Ag2CO3 is 8.1×10-12]
You made up a saturated solution of calcium sulfate (CaSO4). The temp is 25 degrees Celsius. You then add 5.00*10^-3 of sodium sulfate (Na2SO4). What are the concentrations of calcium and sulfate after equilibrium is reached? The pKs of CaSO4 is 4..
