What is the total number of outer (valence) electrons in carbon dioxide, co2? answer?
Anuta_ua [19.1K]
Carbon dioxide has a total of 16 valence electrons.

1. To determine the number of valence electrons of carbon dioxide (CO2), first determine the number of valence electrons of each of the elements in the molecule. 

a. We have 1 carbon (C) molecule, and 2 oxygen (O) molecules. 

b. The carbon molecule has 4 valence electrons and each oxygen molecule has 6 oxygen molecules. 

2. Add up the valence electrons of each of the elements

   4            +          (2 x 6)      = 16
(from C)           (2 oxygen molecules, with 6 valence electrons each)

Thus, CO2 has a total of 16 valence electrons. 

The number of valence electrons can be more clearly seen from the Lewis structure of the CO2 in the figure below (Source: http://chemistry.tutorvista.com/inorganic-chemistry/bonding-electrons.html). The the dots surrounding the letters represent the valence electrons.

Blood ph is kept near a value of 7.3 - 7.5 because of
Ede4ka [16]

Answer:  Neutral Value

Explanation:  pH of the blood is maintained at 7.0 to 7.5that is neutral value.

This is because if the pH of the is lower than the maintained value then it will become acidic .

Acidic pH can cause the medical urgency known as acidosis leading to vomiting, diarrhea etc.

If the pH becomes higher, then the blood will become basic in nature and it can also leas to the death of the person.

That is why the pH of the blood is maintianed at neutral value of 7.0 to 7.5

8. Bring the balloon in contact with the wall. What happens to the charges in the wall?
Ne4ueva [31]

When the charged balloon is brought near the wall, it repels some of the negatively charged electrons in that part of the wall. Therefore, that part of the wall is left repelled.

<u>Explanation</u>:  

  • Balloons don't stick to walls. However, if you rub the balloon on an appropriate piece of material such as clothing or a wall, electrons are pulled from the other material to the balloon.
  • The balloon now as more electrons than normal and therefore has an overall negative charge. Two balloons like this will repel each other.
  • The other material now has an overall positive charge. Because opposite charges attract, the balloon will now appear to stick to the other material. If you didn't rub the balloon first, it's charge would be neutral and it wouldn't stick to the wall.

Strengths as bases:<br>H2O, F-, Cl-, NO,, and CN- <br>​
navik [9.2K]

Answer:

Cl^-<NO3^-<H2O<F^-<CN^-

Explanation:

When we talk about base strength we are referring to how easily a chemical specie accepts protons.

The greater the ability of a specie to accept H^+, the greater its base strength.

The order of increasing base strengths of the species listed are shown in the answer above.
