Answer:

Explanation:
If l = 3, the electrons are in an f subshell.
The number of orbitals with a quantum number l is 2l + 1, so there
are 2×3 + 1 = 7 f orbitals.
Each orbital can hold two electrons, so the f subshell can hold 14 electrons.

<u>Answer:</u> The final volume will be 14.85 L.
<u>Explanation:</u>
To calculate the final volume when temperature increases, we use Charles' Law.
This law states that volume is directly proportional to the temperature of the gas if number of moles and pressure remains constant.

where,
= Initial volume and temperature
= Final volume and temperature
We are given:

Putting values in above equation, we get:


Hence, the final volume of the gas is 14.85L
Answer : The mass of oxygen combined with 1.00 g of carbon in carbon dioxide will be, 2.66 grams.
Explanation :
Law of multiple proportion : It states that when two elements can combine to form two or more different compounds then the mass of one element compared to fixed mass of the other will always be in a ratio of small whole numbers.
As we are given that the mass of ratio of carbon and oxygen in CO is 1 gram and 1.33 gram.
Ratio of C and O in CO = 1 : 1
Ratio of C and O in CO₂ = 1 : 2
So, the mass of ratio of carbon and oxygen in CO₂ will be 1 gram and (2×1.33) 2.66 gram.
Thus, the mass of oxygen combined with 1.00 g of carbon in carbon dioxide will be, 2.66 grams.
