Answer: Option (d) is the correct answer.
Explanation:
Atomic number of carbon is 6 and its electronic distribution is 2, 4. Therefore, in order to become stable and completely fill its octet carbon readily share its valence electrons with another atom.
For example, 
A carbon atom is also able to form a double double with valence electrons of other atom.
Thus, we can conclude that a carbon atom has a strong tendency to share electrons.
Answer:
77 L of water can be made.
Explanation:
Molar mass of 
= 32 g/mol
So, 55 g of = 
mol of = 1.72 mol of
As hydrogen is present in excess amount therefore is the limiting reagent.
According to balanced equation, 1 mol of produces 2 mol of 
.
So, 1.72 mol of produce 
mol of or 3.44 mol of .
Let's assume gas behaves ideally at STP.
Then, 
, where P, V, n, R and T represents pressure, volume, no. of moles, gas constant and temperature in kelvin scale respectively.
At STP, pressure is 1 atm and T is 273 K.
Here, 
= 3.44 mol and R = 0.0821 L.atm/(mol.K)
So, 
Option (b) is correct.
Species that have the same number of electrons or the same electronic structure.
Answer:
Option-A [<span>Cl (g) + e</span>⁻ <span> → Cl</span>⁻<span> (g)] is the correct answer.
Explanation:
First electron affinity is the amount of heat evolved when an electron is added to a neutral atom.
Such problems often come in questions related to Born-Haber Cycle topic. Let suppose Mg and Cl</span>₂ is reacted to form<span> MgCl</span>₂ crystal.
Then the Cl₂ gas is first atomized as follow,
Cl₂ → 2 Cl
After atomization an electron is added to neutral chlorine atoms, as,
Cl + e⁻ → Cl⁻
So, option A is correct choice.
