Answer: Option 1, 4 and 5 describe acids accurately.
Explanation:
Option 1: Acids have a sour taste because of the concentration of ion.
Option 2: They are corrosive in nature, that is they are not at all gentle with the skin and fabric as some acids intend to burn skin such as is a strong acid which can burn skin as well as fabric.
Option 3: Acids need electrons to release ions and non-metals do not donate electrons hence, there is no reaction between a non-metal and an acid.
Option 4: All acids do contain hydrogen. They dissociate in the presence of water to produce ions.
Option 5: Acids do conduct electricity that is they carry electrical charges. This was explained by Arrhenius. He said that the acids dissociate into ions, when it is dissolved in water. These ions hence acts as charge carriers in water.
Answer: The average kinetic energy of the molecules will increase.
Explanation: We are given a container having fixed volume of 5.00L and there is an increase in the temperature of the cotainer from 20°C to 250°C.
The average kinetic energy is directly related to the temperature of the gas.
Mathematically,
From the above expression, as we increase the temperature of the gas, the average kinetic energy of the gas increases and vice-versa.
In the given question, the temperature of the gas is increasing and hence, the average kinetic energy of the molecules will also increase.
