<span>The effective nuclear charge of an atom = total electrons - inner electrons
For O, ENC = 8 - 2 = 6
For Li, ENC = 3 - 2 = 1
For C, ENC = 6 - 2 = 4
The electrons in O experience the greatest effective nuclear charge and that is why O is smaller than C (which is smaller than Li).</span>

Definition of a Portfolio:
Portfolio can be defined as a physical collection of student work that includes materials such as written assignments, completed tests, artwork, lab reports, physical projects and other material evidence of learning progress and academic accomplishment, including awards and honors,

Answer:
The molarity is 0,4M
Explanation:
The molartity is moles of compound (in this case KCl) in 1 liter of solution :
2 L----------0,8 moles KCl
1 L-----------x= (1L x0,8 moles KCl)/2L= 0,4 moles KCl--> 0,4M
