A 4kg parcel of dry air initially at p=950mb and T=295K compresses isobarically to one third of its original volume, Calculate the final temperature and the work done
The buret is filled with the NaOH titrant and the initial volume reading is immediately recorded without waiting the recommended 10-15 seconds. However, in part b-1, the 10-15 second time lapse does occur before the reading is made.
Imagine a small electron-sensitive probe of volume 1.00pm^3 insterted into an H2+ molecule ion in its ground state. Calculate the probability that it will register the presence of an electron at the following positions
