Answer:
Na3PO4 is excess reactant, CaCl2 is limiting reactant.
Explanation:
3CaCl2 + 2Na3PO4 ---> Ca3(PO4)2 + 6NaCl
from reaction : 3 mol 2 mol
given: 6 mol 5 mol (X)
X = (6*2)/3 = 4 mol Na3PO4
For 6 mol CaCl2 we need 4 mol Na3PO4, but we have 5 mol Na3PO4,
Na3PO4 is excess reactant, so CaCl2 is limiting reactant.
BCl₃ is Lewis acid, that is an acceptor of electronic couple. Borum accepts electronic couple on the emptiest orbital.
BCl₃ + HCl = H[BCl₄]
BCl₃ + Cl⁻ = [BCl₄]⁻
Lewis base
acid
