Answer:
Final temperature of the gas is 576 .
Explanation:
As the amount of gas and pressure of the gas remains constant therefore in accordance with Charles's law:
where and
are volume of gas at
and
temperature (in kelvin scale) respectively.
Here ,
and
So
849 K = (849-273) = 576
So final temperature of the gas is 576 .
Answer: The pair that consists of a base and its conjugate acid in that order.
Explanation:
According to the Bronsted-Lowry conjugate acid-base theory, an acid is defined as a substance which looses donates protons and thus forming conjugate base and a base is defined as a substance which accepts protons and thus forming conjugate acid.
is gaining a proton, thus it is considered as a brønsted-lowry base and after gaining a proton, it forms
which is a conjugate acid.
