The molar mass of monotonic Nitrogen is 14 g/mol. Since this is diatomic Nitrogen, double that to 28 g/mol.
Next, divide total mass by molar mass, 500 g / 28 g/mol, which gives <span>17.8571 moles. A mole is defined as being 6.022*10^23 molecules, so multiply moles by molecules/mol (Avogadro's number), and we finally end up with something like 1.075 * 10^25, give or take a few billion particles.</span>
1. Resonance structures are a better description of a Lewis dot structure .
2. Best resonance structure is the one with the least formal charge.
<u>EXPLAINATION OF RASONANCE STRUCTURE OF CARBON DIOXIDE</u>
1.Carbon dioxide has three resonance structures .
2. The CO2 molecule has a total of 16 valence electrons ,
1C = 4 electrons
2O= 12 electrons
<u>three resonance structures for CO2</u>
1. The atoms in all three resonance structures have full octets;
structure 1 will be more stable because it has no separation of charge.
2. Structures 2 and 3 show charge separation caused by the presence of formal charges on both oxygen atoms.
The balanced equation
for the reaction is
CO(g) + 2H₂(g) ⇄ CH₃OH(g)
The given
concentrations are at equilibrium state. Hence we can use them directly in
calculation with the expression for the equilibrium constant, k.
expression for k can be written as
k = [CH₃OH(g)] / [CO(g)] [H₂<span>(g) ]²
</span>[H₂<span>]=0.072 M
[CO]= 0.020M
[CH</span>₃OH]= 0.030 M
From substitution,
k = 0.030
M / 0.020 M x (0.072 M)²
k =
289.35 M⁻²
<span>
Hence, equilibrium constant for the given reaction at 700 K is 289.35 M</span>⁻².

Answer:
Nonmetals
Explanation:
Nonmetals typically lacks the metallic bonding which allows substances to exhibit metallic properties that confers special properties on them.
- Metals are malleable and ductile
- They are also able to conduct electricity due to the sea of electrons present within their structure.
- Metals can be made into wire and drawn into sheets.
Nonmetals lacks these properties but metalloids are able to show some of the properties under certain and special conditions.
