Answer:
The new volume of the balloon be .
Explanation:
We have,
Initial volume is 556 cm ³
The temperature of the balloon decreases from 278 K to 231 K.
We need to find the new volume of the balloon if the pressure is constant.
The Charles law states that at constant pressure, the volume of gas is directly proportional to its temperature i.e.
, P is constant
So, the new volume of the balloon be .
The generic equation for a reaction between an acid and water is
When an acid "reacts" with water, water acts as the base that accepts the proton (H+) from the acid. The remaining ion that is formed after the acid has donated its proton is called the conjugate base (
), and the conjugate acid-base pair is 
- .
Hydrogen sulfate (
) is an ion from sulfuric acid. It is still an acid in itself and can "react" with water ((
) to form the sulfate (
) and hydronium (
)ions.
Based on the previous discussion,
is identified to be the conjugate of the acid 
. Thus, the conjugate acid-base pair is 
.
