2 answers:
Answer: Option (d) is the correct answer.
Explanation:
A molecule or compound which has large molecular mass will be the heaviest in nature.
Since we have to find the heaviest gas out of the given options, so we will calculate the molar mass of each gas as follows.
Molar mass of = 16 g/mol
Molar mass of = 16.04 g/mol
Molar mass of = 44.01 g/mol
Molar mass of = 70.90 g/mol
Thus, we can conclude that out of the given options is the heaviest gas.

Explanation:
Hello there!
In this case, according to the given information, it turns out possible for us to calculate the absorbed heat by considering this is a process involving sensible heat associated to the vaporization of water, which is isothermic and isobaric; and thus, the heat of vaporization of water, with a value of about 2259.36 J/g, is used as shown below:
Thus, we plug in the mass and the aforementioned heat of vaporization of water to obtain the following:

Answer: Linear
Explaination: The central atom of a carbon dioxide molecule is carbon. Carbon is tetravalent which just means it has 4 valence electrons. Because the valence shell isn’t full, the carbon atom can bond with other atoms creating a total of 4 bonds. This then allows the carbon to double bond with 2 oxygen atoms. Now, the atoms in the CO2 molecule Don’t share the electrons evenly because of atomic number or proton count. Because oxygen has an atomic number of 6, carbon has an atomic number of 4, and opposites attract (referring to the positivity of the nucleus and the negativity of the shared electrons), the oxygen atoms will have a slightly negative charge (-) and the oxygen will have a slightly positive charge (+ ). Therefore, the slightly negative oxygen atoms repel creating that linear shape.
