During Electron Impact Mass Spectrometry (EIMS), some bonds
break and smaller ionic parts (fragments) will form. Only cationic
fragments can be detected in EIMS. As a rule of thumb, the more
stable a cation, the more likely it will form and the more likely
it will be detected by the instrument. When a single bond breaks in
the molecule given in question 1), which cationic fragments are
likely to form in an EIMS instrument? Show at least two structures

During a mass spectrometry experiment you were able to obtain the atomic mass and relative abundances of an unknown element. What is the name of this element, how you determine the element based off of the information given? The unknown has three naturally occurring isotopes: 19.99 amu at 90.92%, 20.99 amy at 21.99%, and 21.99 amu at 8.82%.

Polarity and Solubility Predictions. MY DRUG : KLONOPIN Directions: Show your molecule below. Circle or highlight all polar portions of the molecule. Make a reasonable prediction about whether your molecule will be soluble in water or not and explain your reasoning. If your molecule seems to be borderline in polarity, making it difficult to predict solubility, explain your reasoning and the difficulty involved. Find a source (Merck Index, PDR, etc.) that discusses the water-solubility of your drug. Compare your predictions...

I did an physics experiment about change to mass ratio of electron. My magnetic field calculatiom is 1.75 * 10^(-3) T. my experiment manual asked me to compare it with earth field value (5 * 10^(-5)), and how this might affect my measurement. How might this affect my mrasurement??

Torques and Center of Mass. The
Experiment:
In this experiment, you balance a meter stick, to balance the
meter stick, attach masses at positions until the system is in
equilibrium.
The meter stick acts as if all its mass was concentrated at its
center of mass. With the fulcrum at the center of mass, r (the
distance from the axis of rotation to the place where the force is
applied) is 0, so there’s no torque due to the meter...
