A coin dealer heated gold (specific heat = 0.129 J. g -1 . C -1) coins to 100.0 degress C in boling water and then dropped the hot coins into 43.0 g of water at a temperature of 15.5 C in a coffee cup calorimeter. The final temperature of the water and the coins was 21.5 C.
A hiker caught in a thunderstorm loses heat when her clothing becomes wet. She is packing emergency rations that, if completely metabolized, will release 30 kJ of heat per gram of rations consumed.
consider the following mixtures. in each case either calculate the pH if the resulting solution is a buffer solution or state why the solution does
Consider the following reaction: SO2Cl2 (g) SO2 (g) + Cl2 (g). K = 2.99*10^-7 at 227 degrees celsius. If a reaction mixture initially contains 0.159 , what is the equilibrium concentration.
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?
b) Determine the hybrid state of each C. c) Draw the molecule geometrically correctly showing its ?- and ?-bonds and the atomic orbitals used to form each bond.
The elements of group 1 (Li-Cs) are very electropositive because of A. they all have small atomic radii B. they all have high second ionisation energies C
Balance the following skeleton reaction, calculate Ecell, and state whether the reaction is spontaneous:
A gaseous mixture of O2 and N2 contains 40.8% nitrogen by mass. What is the partial pressure of oxygen in the mixture if the total pressure is 405mmhg
What is the H3O+ concentration of the solution?
calculate the external pressure that must be applied to seawater, 1.14 M total ion concentration at 10 degrees celcius if the maximum concentration allowed in the product water
The compound NOCl decomposes to nitric oxide and chlorine according to the following equation: 2 NOCl (g) ? 2 NO (g) + Cl2 (g) Suppose that 0.420 mol NOCl is placed in a 3.00-L flask at a given temperature
The combustion of ethane produces carbon dioxide and steam: 2C2H6 + 7O2 --- 4CO2 +6H20 How many moles of CO2 are produces when 5.55 mol of ethane are burned in an excess of oxygen.
