When zinc oxide reacts with dilute nitric acid, zinc nitrate is produced. The equation for the reaction is: ZnO + 2HNO₃→ Zn(NO₃)

₂ + H₂O. Use 0.200 mol of nitric acid reacts with excess zinc oxide. A mass of 15.3 g of zinc nitrate is produced. Calculate the percentage yield of zinc nitrate. [Mr of zinc nitrate = 189]

ZnO + 2HNO₃→ Zn(NO₃)₂ + H₂O

mol Zn(NO₃)₂ = mol ZnO = 0.2 (from the coefficient)

mass Zn(NO₃)₂ = 0.2 x 189 = 37.8 g (theorethical yield)

% yield = 15.3 : 37.8 x 100% = 40.48%

Why cant (NaCl) light the bulb until the NaCl is dissolved in water. *
Aneli [31]

Answer:

NaCl will only conduct electricity in solutions

Explanation:

For electrical conduction, free mobile electrons as seen in most metals must be present or ions which are charged particles must be available for solutions and molten substances.

  • Sodium chloride is an ionic compound without free mobile electrons or ions despite being ionic.
  • It will maintain a subtle and unique charge stability when in solid form.
  • In solid, the ions are not free to move and remain locked up in the solid mass.
  • When introduced into a solution, the ions becomes free to move and this will aid electrical conduction.
