Question

8) when aquenous gowtions of ammonium carbonate and potassium sulfate are mixed, will a pool precipate form? 9. for the reaction - which sons are spectator ons Zn(s) + CuSO4 lag) ZnSO4 (ag) thuis) 10) An Isothermal process is one in which the does not change (11) 12.1°C, gas occupied a volume of 4,938 L under 1.595 atm expanded to 8.4142 - What is the temperature of heated gas. (12) @ 18.3°c, gas occupred volume of 7.185 L under 2.457 atm. heated & compressed = 7.521 atm & temp 81.14 What is new volume? 1) pressure exerted by 5.492 g of the du 5.4929 of +2 in 2.893 2 @ 2031.80 in R=0.0820584 L atm/kmol what pressure?

Answer 1

I In an isothermal process temperature of system does not chan! (8) Amor Lun Cao, bonate :- (NH4)2 có 4 = 0 Potassium sulfate :- K2504 Now in ageous solution of this salt contains cation and anion (Nrt co 2 kt so 2 the substitution reaction takes place. (NH4), C03 (aq) + K2 50q (aq) – K2 C03 (24) Whe + (NH4), 50 But (NH), SO is highly soluble in ageous solution. So it does not give any precipitate. & Zn (s) + Cu sog (aq) & Zusog Cu (3) spec taton ions are those which does not take part in reaction , present as a spectaton only. Cuso in ageous medium Cuso 2 + + 50 and main reaction happen between in and au 2+ In Zn2+ + 2e and Cu2+ + 2e C ut :Int and s0,2 forom Zn Son 69) 502 is the spectator ion of this reaction.
