Answer:
g HCN = MW HCN g/mole HCN * [8.00E19 molecules/6.022E23 molecules/mole HCN] = ??
EmForm = CaxPy
moles Ca = 0.66g / atwt Ca g/mole = ??
moles P = (1.00-0.66)g / atwt P g/mole = ??
x/y = moles Ca / moles P = ?? (express as ratio of two numbers; if both are not intergers multiply each by the same number that make them integers. This ratio gives the empirical formula.

Aniline has smallest Rf value on silica gel since it is more polarthan the other compounds because aniline is a hydrogen donor and acceptor itmakes the molecule more attracted to the silica gel which is also also polar as<span>‘likes dissolve likes.’</span>
Answer:
Divergent boundaries – where two plates are moving apart. Divergent boundaries within continents initially produce rifts, which produce rift valleys. The most active divergent plate boundaries are between oceanic plates and are often called mid-oceanic ridges.
