Question

complete the following equation: silver nitrate+iron, sodium+water, zinc+sulphuric acid

Answer 1

Answer:

2AgNO3 + Fe = Fe(NO3)2 + 2Ag

2Na + 2H2O = 2NaOH + H2

Zn + H2SO4 = ZnSO4 + H2

Explanation:

1) The first reaction is an displacement reaction. As Iron is more reactive than Silver it displaces it and forms Iron Nitrate and silver metal respectively.

2)The second reaction is an exothermic reaction. Sodium combines with water to form an alkali Sodium Hydroxide. this reaction also produces Hydrogen gas.

3)The third reaction is also a displacement reaction. here, Zinc displaces Hydrogen to form Zinc Sulphate and Hydrogen gas.
