Answer:
In case of low-mass stars,the outer layers of the low mass stars are expelled as the core collapses such that the outer layers form a planetary nebula.
Explanation:
In case of low-mass stars,the outer layers of the low mass stars are expelled as the core collapses such that the outer layers form a planetary nebula. The core remains as a white dwarf and finally become a black dwarf as it cools down. A low mass star consumes its core hydrogen and turns it into helium over its lifetime.
The second one, I could be mistaken though

I believe it is B but I am not entirely sure! don't do this is B doesn't sound or look right to you!
Answer:
The rows on the periodic table are called periods. All the elements in a period have valence electrons in the same shell. The number of valence electrons increases from left to right in the period. When the shell is full, a new row is started and the process repeats.

I hope it helps plz let me know if it is right or wrong.</h2>
Answer:
We will use ideal gas equation in this problem
PV = nRT
Where
P = pressure of gas or air = ?
V = volume of air = volume of pressure cooker = 5.68 L
T = temperature = 394 K
n = moles of air = 0.355
R = ideal gas equation = 0.0821 L atm / mol K
Putting values
Pressure = nRT / V = 0.355 X 0.0821 X 394 / 5.68 = 2.02 atm.
