In a time-of-flight mass spectrometer an ion having m/z of 22,000amu is accelerated with a voltage of 2500 V. The drift tube is 2.00 meters long. 1. Explain how much time is required for the ion to reach the detector
calculate the theoretical yield percentage of a reaction between sodium and water if 25.0 g of sodium react with excess
How much heat is absorbed by 100 mL of a dilute solution of NH4NO3 as it changes its temperature from 22.4 degrees C
Assume the reaction A+B-->C+D proceeds to equilibrium. Calculate the equilibrium concentration of D at 25 o C, given that the staring concentrations of A and B are 2M and delta G for the reaction is 1.0 kcal/mol. R=1.987cal/mol.K
Why does OF2 have a single bond. Why not double bond? Wouldn't it be better to use a double bond and then O wouldn't have a lone pair and F would have one lone pair less? How can I know if to use single, double or triple bond
