Masses of Atomic Particles Figure 8 An adult rhino can have a mass of 1400 kg. The mass of a small egret is about 0.76 kg. What is the ratio of these two masses? How does this ratio compare to the ratio of the mass of a proton to the mass of an electron? MIKRO SKIRTS ki KAMI Complete the table. Particle Symbol Mass (amu) p neutron 1,840 1 1,840​

Consider the directing effects of the substituents on salicylamide and predict the possible structures of the iodination products. which do you think will be the major product?

)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.
