Answer:
The volume will be 2600 L.
Explanation:
Initial temperature (
) = 25°C = (25 + 273) K = 298K
Final temperature (
) = 54°C = (54 + 273) K = 327 K
By using the combined gas law equation,
= 
or, 
= 
or, 3060 × 327 = 380 × 
or, ≈ 2600 L
Hence the volume of the balloon will be about 2600 L.

The correct answer is:
C. valence.
Explanation:
The valence or valency of an element is a stratagem of its connecting power with other atoms when it makes chemical compounds or molecules.
A valence electron is an outer shell electron that is connected with an atom, and that can compete in the formation of a chemical bond if the outer shell is not closed; in a single covalent bond, both atoms in the bond provide one valence electron in order to form a shared pair
