Calculate the theoretical amount of CaCl2 that would be required to change the temperature of 50.0 mL of water from 20C to 45C. The heat capacity of water is given as 4.184 J/degree, and the density of water is given as 1 g/ml
Use enthalpy of formation data to calculate the number of moles of CO2(g) produced per megajoule of heat released from the combustion of each fuel under standard conditions
The decomposition of SO2CL2 to SO2 and Cl2 is first order in SO2CL2 and has a half-life of 4.1 hours. If you begin with 1.6 x 10^-3 moles of SO2CL2 in a flask, how many hours elapse until 2.00x10^-4 moles remain?
If 0.7438 g of potassium hydrogen phthalate is used and the equivalence point occurs at 33.00 mL of NaOH, calculate the molarity of the NaOH solution to the correct number of significant figures.
100 mL of .200 M HCl is titrated with .250 M of NaOH. What is the pH after 50 mL of the base has been added. What is the pH at the equivalence point
How much energy (in kilojoules) is released when 26.0 of ethanol vapor at 93.5 is cooled to -13.0? Ethanol has = -114.5 , = 78.4 , = 38.56 and = 4.60 . The molar heat capacity is 113 for the liquid and 65.7 for the vapor.
How much energy must be supplied to break a single 21Ne nucleus into separated protons and neutrons if the nucleus has a mass of 20.98846 amu. What is the nuclear binding energy for 1 {\rm mol} of {\rm ^{21}Ne}
what is the ph of a solution prepared by dissolving 2.89 g of calcium nitrite in 0.675 l of water?1. briefly explain
Compounds of boron and hydrogen are remarkable for their unusual bonding and also for their reactivity. With the more reactive halogen
Suppose the pH of the water is 3.88 and that the concentration of iron(II) in the water is 2.30x 10-5 M, what is the potential of the corrosion reaction under the above conditions at 298 K?
Experimentally observed facts have led to the establishment of rules used to predict the solubility of common compounds in water. The rules can be stated as follows: Compounds that contain , , , and are always soluble with no particular exceptions..
