Write and Balance: Exothermic reaction between aqueous sodium hydroxide and sulphuric acid.

1 answer:

7 0

Exothermic reaction discharges energy in forms of light, heat or sound, thus it is represented by negative flow of heat. In this equation:

NaOH (aq) + H2SO4 (aq) à H2O (l) + Na2SO4 (aq)

When the solution of Sodium hydroxide is added to the Sulphuric acid, water and Sodium sulfate is produced. To balance this, we put (2) two on Sodium hydroxide and (2) two on water.

2NaOH (aq) + H2SO4 (aq) à 2H2O (l) + Na2SO4 (aq)

Aluminium containers are used to store and transport nitric acid(HNO3) but not NAOH why?

alex41 [277]

Answer:

(i) Concentrated HNO3 can be stored and transported in aluminium containers as it reacts with aluminium to form a thin protective oxide layer on the aluminium surface. This oxide layer renders aluminium passive. (ii) Sodium hydroxide and aluminium react to form sodium tetrahydroxoaluminate(III) and hydrogen gas.

What is the relationship between the number of gas particles and volume ?

choli [55]

Answer:

V ∝ n

Step-by-step explanation:

Suppose that pressure and temperature are constant.

If you try to force more molecules of air into a balloon, the balloon will expand.

This is an example of Avogadro's Law: the volume of a gas is directly proportional to the number of moles (particles).
