Chemistry
1 answer:
abruzzese [7]3 years ago
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

These are  diseases that affect primarily the lungs or any other part of the respiratory system.

<h3>What are respiratory disorders?</h3>

The term respiratory disorders refers to those diseases that affect primarily the lungs or any other part of the respiratory system. These are the diseases that prevent a person from breathing in and out normally and prevent the lungs from playing its usual role in gaseous exchange.

The respiratory disorders could be able to make a person not to be able to breathe well and it may lead to hospitalization and death of the patient of adequate treatment is not sought from an expert who could diagnose and treat such respiratory disorders.

The common types of respiratory disorders are;

  • asthma

To what temperature must a balloon, initially at 25°C and 2.00 L, be heated in order to have a volume of 6.00 L
andreyandreev [35.5K]

Answer:

894 deg K

Explanation:

The computation is shown below:

Given that

V1 denotes the initial volume of gas = 2.00 L  

T1 denotes the initial temperature of gas = 25 + 273 = 298 K  

V2 denotes the final volume of gas  = 6.00 L  

T2 = ?

Based on the above information

Here we assume that the pressure is remain constant,

So,  

V1 ÷ T1 = V2 ÷ T2  

T2 = T1 × V2 ÷ V1

= (298)(6) ÷ (2)

= 894 deg K

I NEED HELP PLEASE, THANKS! :)<br><br> Draw the Lewis structure for sulfur trioxide, SO3.
butalik [34]

Answer:

Explanation:

Sulfur has valence electron 6 and oxygen has 6*3 = 18 valence electrons. In this drawing, you'll see that sulfur violates the octet rule that is it has more than 8 electrons but it is legal since sulfur is in 3rd period, and elements that fall in 3rd period or more in periodic table can use their d orbitals and others to go beyond the normal "8" electrons in valence shell rule which is octet rule

All the formal charges are minimized...that is everything has formal charge of 0 in this structure which is always encouraged.

Credits to chemistNATE who wonderfully explains it in his video.
