Question

4) Give the molecular equation, the complete ionic equation and the net ionic equation to consult your solubility chart) Potassium phosphate + magnesium acetate -------- Molecular Eq (3pts) = ALTO Complete ionic eq (3 pts) = Net ionic eq (3 pts) = 5) Give the heating curve (4 pts) and calculate the heat in KJ (9 pts) needed to convert 56.8 grams of ice at -33.3 degrees C to liquid water at 66.9 degrees C. The specific heat of ice, water, and steam are 0.48.1.00, 0.49 calories/g °C respectively. The heat of vaporization of water is 540.0 cal/g and the heat of fusion of water is 80.0 cal/g, you may or may not need to use all of these values] Remember give the answer in KJ.

Answer 1

Formation of magnesium phosphate [ Mg3(PO4)2](s) as precepitate.

n 9. Potassium phosphate + magnesium acetate → Solo Molecular equation: 2 K3PO4 (aq) + 3 M9 (CH2C00), (6p) → Mg, (PO4), ()1+6KCHacov) (29) Complete fonic equation, 6Kt ca)+2PO2 (09.) + 3Mjeq.) + 6 CH3C00(04) — Mg CP04), + сква + Gegepo Сая) Net Sonic equation 3 Mg2+aq.) + 2PO4% (09.) → Mgs (PO4)2 )
