We are taught that the gases do not have a specific volume, but they occupy all the space that is given to them. Why do we say that 1mol of an ideal gas occupies 22,4L in STP? How is that possible? If we put 1mol of ideal gas in a whole room, will it just occupy 22,4L???
What is the minimum number of microwave photons with a wavelength of 3.07 mm that will have to be absorbed by a 126.00 gram sample of water to heat it from 25°C to 100°C?
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?
if 20 ml of .01 m hcl is required to titrate 50 ml of a saturated ba(oh)2 sol how many moles of hydroxide ion were present in the barium solution
Consider the dissolution of CaCl2. CaCl2(s) Ca2+(aq) + 2 Cl-(aq) ΔH = -81.5 kJ A 13.2 g sample of CaCl2 is dissolved in 106 g of water, with both substances at 25.0°C.
An equilibrium mixture contains {\rm{N}}_2 {\rm{O}}_4, (P = 0.27 atm) and {\rm{NO}}_2 (P = 1.2 atm) at 350 {\rm K}. The volume of the container is doubled at constant temperature.
What is the pH of a solution of 0.700 M K2HO4, potassium hydrogen phosphate. What is the pH of a solution of 0.450 M KH2PO4, potassium dihydrogen phosphate
The rate of the reaction will increase if the pressure of the gases increases. The rate of the reaction will remain constant with increasing temperature. The rate of the reaction will increase as time increases.
Predict the products of the following reactions: W(CO)5[C(C5H52)(OC2H5)] +BF3 ? (C5Me5)Rh(CO)2? Will I know that the final answer has to be: W(CO)5[C(C5H5)(OC2H5)] +BF3 ? [(CO)5W?CC6H5]+ +F-+F2BOC2H5 (C5Me5)Rh(CO)2? [(C5Me5)Rh(CO)]2 +2CO
