The simplest atomic nucleus in nature is molecular formula of hydrogen, which consists of a single proton. individual protons have charge and can be thought of as small spinning spheres. a charged spinning sphere will generate a magnetic field, whose direction is indicated by the magnetic moment of the object, vector mu. in what direction will the proton rotate, based on the direction of its magnetic moment and the direction of the uniform magnetic field that it is immersed in:

Consider the four elements above. which one of these elements will combine with oxygen in a 1: 1 ratio?

How many moles of oxygen react with 12 moles of aluminum

)benzene and toluene form nearly ideal solutions. consider an equimolar solution of benzene and toluene. at 20 °c the vapour pressures of pure benzene and toluene are 9.9 kpa and 2.9 kpa, respectively. the solution is boiled by reducing the external pressure below the vapour pressure. calculate (i) the pressure when boiling begins, (ii) the composition of each component in the vapour, and (iii) the vapour pressure when only a few drops of liquid remain. assume that the rate of vaporization is low enough for the temperature to remain constant at 20 °c.
