    Ionize Iron powder/filing

    Hi all, I am searching for an effective way to obtain electrically charged iron powder grain. I thought that one way could be ionizing the grain with a REDOX. Is that possible? Are there references to read how such process can be performed in safety? You have in mind other ways to leave the...

    oseltamivir ionization

    Hi I was working though a practice test and just have a quick and possibly obvious question. I was asked to draw oseltamivir ionized at physiological pH 7.4 At pH 7.4 I thought the primary amine and the secondary amine would both accept a hydrogen and both acquire a positive charge I don't...

    Enthalpy of ionization?

    If the heat of neutralization of aqueous benzoic acid (a weak monoprotic acid) is -54.6 kJ/mol , what is the enthalpy of ionization of benzoic acid? I know that the formula for delta H = qrxn/ moles reacting I'm not sure how to find it. Any help appreciated!

    Ionization of HCl

    In this problem, I'm asked to find the ionization of HCl I wrote it as: HCl + H2O --> H3O^+ + Cl^- but in my book I see it written as: HCl --> H^+ + Cl^- is this another way of writting it? Also,when writing these equations out in general does it matter in what order you write out the...

    Changes in Energy due to Ionization

    Mg(g) > Mg+(g) + e- Change in E = 735 Mg(g) > Mg charge 2+(g) + e- Change in E = 1445 O(g) + e- > O- Change in E = -141 O-(g) + e- > O charge 2- Change...
