Identify the precipitate in this reaction: calcium nitrate reacts with sodium phosphate.
Marat540 [252]
3Ca(NO₃)₂(aq) + 2Na₃PO₄(aq) → Ca₃(PO₄)₂(s) + 6NaNO₃(aq)

3Ca²⁺ + 6NO₃⁻ + 6Na⁺ + 2PO₄³⁻ → Ca₃(PO₄)₂ + 6Na⁺ + 6NO₃⁻

3Ca²⁺ + 2PO₄³⁻ → Ca₃(PO₄)₂  (calcium phosphate is the precipitate)

A lone pair must reside in which orbital type(s) to participate in resonance/conjugation/delocalization?
tino4ka555 [31]

If a lone pair is participating in resonance, this capability the atom is both Sp2 or Sp hybridized. Looking at the Sp2 case, that ability there are 3 Sp2 orbitals and one P orbital. Assuming there is no formal cost on the atom, the three hybrid orbitals are used for bonding and the lone P-orbital holds the lone pair. Sp3 orbitals are no longer involved with resonance so the lone pair worried in resonance should never be in an Sp3 orbital.

A mathematically described area round a nucleus in an atom or molecule that may also include zero, one, or two electrons Electrons organize themselves in cloudlike areas round the nucleus referred to as orbitals.
