The following heats of formation are used to find the change in enthalpy for the formation of tin chloride in the following reaction Sn (s) + 2Cl2(g) --> SnCl4(l).
Sn(s) + Cl2(g) --> Sn Cl2(l)DH = -186.2 kJSnCl2(s) + Cl2(g) --> SnCl4(l)DH = -325.1 kJ
What is the change in enthalpy?
An analyst is to determine the molarity of a NaOH solution. Three aliquots of standard KHP are weighed out 0.3078g, 0.4967g, and 0.3821g
Determine the freezing point and calculate the final temperature if initially this iron nail was at temperature of 28 degree Celsius?
Heated and allowed to expand against a constant pressure of 1.20 atm until its volume reaches twenty eight Litres. Now determine Which of the given data is correct?
Imidazole, acting as a nucleophile, catalyzes the hydrolysis of phenyl acetate by attach on the carbonyl carbon atom of the ester. The imidazole displaces the phenoxide anion and forms acetyl imidazole
What is the total number of joules absorbed by 65.0 g of water when the temperature of the water is raised from 25.0 degrees celsius to 40 degrees celsius?
The minimum energy required to break an oxygen-oxygen bond in ozone (O3) is 387 kJ/mole. What is the longest wavelength of light
A 5.95-g sample of AgNO3 is reacted with BaCl2 according to the equation to give 3.21 g of AgCl. What is the percent yield of AgCl? AgNO3(aq) + BaCl2(aq) --> AgCl(s) + Ba(NO3)2(aq)
A copper wire (density = 8.96 g/cm3) has a diameter of 0.26 mm. If a sample of this copper wire has a mass of 43 g, how long is the wire?
The temperature in the room was 25.0 ºC. James was asked to transfer 4.50 mL of a liquid (density = 0.895 g/mL at 25.0 ºC) using a buret. He added the liquid into a 50-mL beaker weighing 25.789 g. He weighed the beaker with the liquid and found th..
Draw a rough sketch of the energy profile for each of the following cases. a. E = +10 kJ/mol, Ea = 25 kJ/mol b. E = -10 kJ/mol, Ea = 50 kJ/mol c.
A solution contains 410.3 g of H2SO4 per litre of solution . If the density is 1.243 g/ml, what will be its molarity and molality.
Estimate the magnitude of the absoulte error and percent error in the measured sample volumes. Compare those errors to the errors that occur when measuring volumes of approximately 8mL
