Question

total and net ionic equation nicl2+na2co3

Arcacesi ASasiarro Chem 211 Homework assignment # 3 Due: October 30, 2019 1. Fuel is burned in a cylinder equipped with a piston. The initial volume is 0.250 L and the final volume is 0.980 L. If the piston expands against a constant pressure of 1.35 atm. how much work (in J) is done? (1 Lx atm- 101.3 J) 2. The heat of combustion of methane is AHcomb -890 kJ/mol. How much heat is released when 4.40 g of methane is burned at constant pressure? 3. Calculate the energy of a photon of yellow light with -589 nm.

Answer 1

Ans :

The balanced molecular equation is given as :

NiCl₂ (aq) + Na₂CO₃ (aq) = NiCO₃ (s) + 2NaCl (aq)

The total ionic equation is given as :

Ni²⁺ (aq) + 2Cl^- (aq) + 2Na⁺ (aq) + CO₃^2- (aq) = NiCO₃ (s) + 2Cl^- (aq) + 2Na⁺ (aq)

The common spectator ions from both the sides are cancelled out to get the net ionic equation as :

Ni²⁺ (aq) + CO₃^2- (aq) = NiCO₃ (s)
