6 0

Answer:

Na:[He]3s¹

Explanation:

[He] => core structure => Helium ([He]1s²)

3 => principle energy level of valence electrons

s => orbital geometry of valence structure => spherical

s¹ => orbital orientation of valence structure => 1 orientation for sphere

superscript 1 => 1 unpaired electron in orbital

MariettaO [177]

Answer:

10.54 L

Explanation:

Given that:-

Moles of O_2 = 1.00 moles

According to the given reaction:-

4NH_3+7O_2\rightarrow 4NO_2+6H_2O

7 moles of oxygen gas reacts with 4 moles of ammonia

1 mole of oxygen gas reacts with \frac{4}{7} moles of ammonia

Moles of ammonia = 0.5714 moles

Also, Given that:

Temperature = 850 °C

The conversion of T( °C) to T(K) is shown below:

T(K) = T( °C) + 273.15  

So,  

T₁ = (850 + 273.15) K = 1123.15 K  

n = 0.5714 moles

P = 5.00 atm

Using ideal gas equation as:

PV=nRT

where,  

P is the pressure

V is the volume

n is the number of moles

T is the temperature  

R is Gas constant having value = 0.0821 L atm/ K mol  

Applying the equation as:

5.00 atm × V = 0.5714 moles ×0.0821 L atm/ K mol  × 1123.15  K  

⇒V = 10.54 L

<u>10.54 L of NH_3 required.</u>
