1 answer:
The number of molecules of gases in each of the 3 vessels is the same.
<h3>Number of moles</h3>The first vessel contains 2g of gas:
Number of molecules in 2 g = 2/2 = 1 mole
The second vessel contains 32 g of gas:
Number of molecules = 32/32 = 1 mole
The third vessel contains 44 g of gas:
Number of molecules = 44/44 = 1 mole
Thus, the 3 vessels contain the same number of moles of gases.

Answer:
Lewis structure in attachment.
Explanation:
Atoms of elements in and beyond the third period of the periodic table form some compounds in which more than eight electrons surround the central atom. In addition to the 3s and 3p orbitals, elements in the third period also have 3d orbitals that can be used in bonding. These orbitals enable an atom to form an <u>expanded octet</u>.
The central Xe atom in the XeF₄ molecule has <u>two</u> unbonded electron pairs and <u>four</u> bonded electron pairs in its valence shell.
