Explanation:
When a substance or solution has pH equal to 7 then it is known as a neutral solution. And a solution with pH more than 7 is basic in nature.
Antacid is a base that has chemical formula and it is also known as magnesium hydroxide.
Hence, an antacid has pH greater than 7 (making it basic) so that it can neutralize the acid.
Therefore, when excess of acid is formed in the stomach then there occurs more hydrogen ions. Due to which pain is felt in the stomach and in this situation when an antacid is consumed then it releases hydroxide ions as it is a base due to which acid gets neutralized and we feel relieved.
Hence, we can conclude that the pH of an antacid solution that is used to neutralize excess stomach acid is more than 7.
Answer:
The correct option is;
2) Thermal energy increases by a factor of R
Explanation:
The equipartition energy theorem states that when molecules are in a state of thermal equilibrium, particles within the system posses equal average energy with each degree of freedom which can be known as energy due to a state of having a particular temperature or thermal energy given by the relation
= Kinetic energy of translation + Kinetic energy of rotation + Energy of vibration
For a mono-atomic gas, = 3/2·n·R·T
For a diatomic gas, = 5/2·n·R·T
For a solid element, = 3·n·R·T
Therefore, as the temperature is doubled, the thermal energy increases by a factor of R.
