Terne, originally an alloy of lead (Pb; r = 154 pm, face-centered cubic) and tin (Sn; r = 140 pm), appears to contain approximately 7 tin atoms for every 16 lead atoms. How can this alloy be characterized?

The dispersed phase is liquid and dispersed medium in milk is liquid

Ch4 and ph3 are both covalent since they are composed both of non-metals.    ch4 is non- polar because of  london forces and has a geometry of tetrahedral  ph3 , on the other hand, is umbrella shaped polar and has dipole-dipole intermolecular force (imf) . since ph3 is polar, it has a stronger imf
