14. Which net ionic equation describes the reaction between K3PO4( aq) when it is mixed with Al(NO3)3( aq)?

Al 3+( aq) + PO43-( aq) - AlPO4( s)
-
K+(aq) + NO3(aq) - KNO3(aq)
Al 3+( aq) +3NO3 -(aq) - 3AINO3( s)
-
3K +(aq) + PO43-( aq) – 3KPO4( s)

in the given question, the partial pressure is calculated by using the ideal gas equation, that is, pv = nrt

here, p is pressure, v is volume = 25 l, n is number of moles = 0.0104 moles, r is gas constant = -0.0821 l.atm / mol.k

t is temperature = 273 k

p = nrt / v

p = (0.0104 mol × 0.0821 l.atm / mol.k × 273 k) / 25 l

= 0.0093 atm
