What are the conjugate acid-base pairs in the reaction of H2SeO4 with H2O?H2SeO4+H2O→products

Conjugate acid- H2SeO4

Conjugate base- H2O

Explanation:

The full equation of the reaction is; H2SeO4(aq) + H2O(aq)-->H3O^+( aq) + HSeO4^-(aq).

The conjugate acid is the specie that donates a proton to the conjugate base, hence H2SeO4 is the conjugate acid while H2O is the conjugate base because it accepts a proton from H2SeO4, hence the answer above.

Answer : The volume of balloon at higher altitude will be 654.338 L

Explanation :

Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.

The combined gas equation is,

where,

= initial pressure of gas =

conversion used : (1 atm = 760 mmHg)

= final pressure of gas = 0.0819 atm

= initial volume of gas = 59.0 L

= final volume of gas = ?

= initial temperature of gas =

= final temperature of gas =

Now put all the given values in the above equation, we get:

The final volume will be, 654.338 L

Therefore, the volume of balloon at higher altitude will be 654.338 L
