sdrta.net : The correct depiction of Lewis-dot structure for 5A element, Arsenic is displayed below.
You are watching: What is the correct lewis structure for group 5a element, arsenic?
Lewis-dot structure : It reflects the bonding between the atoms of a molecule and it also shows the unpaired electrons existing in the molecule.
The number of valence electrons displayed by "dot".
The given molecule is, Arsenic
The atomic variety of arsenic = 33
As we know that the number of electrons is equal to the number of atomic number.
So, the number of electrons = 33
The electronic configuration of arsenic is,
The number of valence electrons current in arsenic = 5
The Lewis-dot structure of arsenic is presented below.
VLD <36.1K>11 months ago
Because Arsenic is in team 15 that will receive 5 valence electrons start out by adding one dot roughly the symbol because that Arsenic. You"ll end up through 4 approximately it and all you need to do is include another one.

The temperature that 525 K, for this reason to identify which is the state the a substance, we should now the melting and the boiling suggest of it, which deserve to be uncovered in thermodynamic tables. To it is in liquid, the melting allude must be less than 525 K (so the substance is no a solid anymore), and the boiling allude must be higher than 525 K (so the substance doesn"t walk to gas).
Substance Melting suggest at 1 atm (K) Boiling suggest at 1 atm(K)
Bi 544.7 1837
Pt 2041.4 4098
Se 494 958
Ca 1115 1757
Cu 1357.77 2835
Thus, when pressure increase, the melting suggest decrease, so, if the press is little higher than 1 atm, climate bismuth have the right to be uncovered as a liquid at 525 K. The others would need a greater pressure to be fluid at 525 K.

The 3 chlorine atoms retract electron density via induction. This impact renders the carbonyl group more electrophilic.
Ethyl trichloroacetate(C4H5Cl3O2) is significantly an ext reactive towards hydrolysis 보다 ethyl acetate. This is since the 3 chlorine atoms withdraw electron density via induction and also renders the carbonyl team C=O more electrophlic(tendency come attract more electrons).
Hydrolysis is a chemistry reaction which involves water molecule being added to a substance.
The enhanced electrophilic feature enhances that is reaction v water.

Determine the value of the equilibrium constant, Kgoal, for the reaction N2(g)+H2O(g)⇌NO(g)+12N2H4(g), Kgoal=? through making usage of
K = 1.79x10⁻³³
Using Hess"s law, the is feasible to fin K the a reaction by the algebraic sum of an additional related reactions.
In the reactions:
1. N2(g)+O2(g) ⇌ 2NO(g), K1 = 4.10×10−31 2.
2. N2(g)+2H2(g) ⇌ N2H4(g), K2 = 7.40×10−26
3. 2H2O(g)⇌2H2(g)+O2(g), K3 = 1.06×10−10
The sum of 1/2 (1) + 1/2 (2) produce:
N2(g) + 1/2O2(g) + H2(g) ⇌ 1/2N2H4(g) + NO(g)
And K" = √4.1x10⁻³¹×√7.4x10⁻²⁶ = 1.74x10⁻²⁸
Now, this reaction + 1/2 (3):
N2(g) + H2O(g) ⇌ NO(g) + 1/2N2H4(g)
And K that reaction is:
1.74x10⁻²⁸×√1.06x10⁻¹⁰ = 1.79x10⁻³³
