When you use the Format parameter, Windows PowerShell gets only the properties of the DateTime object that it needs to display the date in the format that you specify. As a result, some of the properties and methods of DateTime objects might not be available.y default, the date-time is displayed in long-date and long-time formats for the system locale. When you pipe a date to cmdlets that expect string input, such as the Add-Content cmdlet, Windows PowerShell converts the DateTime object to a string before adding it to the file.
= 1211 kJ mol-1. Therefore the molar heat of combustion of ethanol is 1211 kJ mol-1 (The molar enthalpy of combustion of ethanol is 1211 kJ mol-1). (Note that the enthalpy change for the reaction is negative because the reaction is exothermic, so the enthalpy change for the reaction is -1211 kJ mol-1, ÎH = - 1211 kJ mol-1)
Calculate kj/mole? When 39.5 mL of 0.625 M H2SO4 is added to 39.5 mL of 1.25 M KOH in a coffee-cup calorimeter at 23.50Â°C, the temperature rises to 30.17Â°C. Calculate H of this reaction. (Assume that the total volume is the sum of the individual volumes and that the density and specific heat capacity of the solution are the same as...
