Answer:
Electron groups could be considered as Lone pair electrons and bonded pairs of electrons.
Answer: Option D & B
Explanation:
The two or more electrons can be bonded by single bond, double bond, covalent bond of electrons can simply be lone pair of electrons. Unshared pair of electrons are generally termed as lone pair of electrons in an atom which are generally present in the outermost shell of atoms. Hence electron groups can be determined by bonded pairs and lone pairs of electrons.

Answer:
Q= 231.88 W/m²
Explanation:
Given that
L= 20 cm
K= 2.79 W/m·K
T₁=50°C
T₂= 22°C
h=15 W/m₂·K
The total thermal resistance
Now by putting the values
R= 0.138 K/W ( for heat flux A= 1 m²)
Heat flux Q= ΔT/R
Q= (50-22)/0.138 = 32/0.138 W
Q= 231.88 W/m²
