Determine the electron geometry (eg) and molecular geometry (mg) of CO2.
eimsori [14]

Answer:

eg=linear, mg=linear

Explanation:

First of all, it must be stated that most triatomic molecules are either linear or bent. This depends on the electron geometry of the molecule and the number of bonding groups, multiple bonds and lone pairs present.

CO2 contains four regions of electron density and two bonding groups. For a specie containing two bonding groups, a linear molecular geometry is expected with an angle of 180°.

For a specie having two bonding groups and no lone pairs with multiple bonds, the expected electron geometry is also linear.

Phosphorus has three electrons in its 3p sublevel and sulfur has four. Phosphorus should have the lower ionization energy but it
Nadya [2.5K]

Answer:

B

Explanation:

First of all it is important to know that a half filled orbital is particularly stable. In phosphorus all the electrons occur singly in the 3p sublevel minimizing inter electronic repulsion hence it is more difficult to remove an electron from this energetically stable arrangement. In sulphur, electrons are paired in one of the 3p orbitals thereby lowering the energy of that level due to instability caused by interelectronic repulsion between two electrons in the same orbital.

In the chemical reaction below, what Is the product? C+o2 -&gt; Co2
vlada-n [284]

Answer:

CO₂

Explanation:

The product of the reaction is CO₂.

In a chemical reaction, the product is the substance usually found on the right hand side of the expression.

  Reaction equation is given as;

          C  +  O₂  →  CO₂  

In this reaction, C and O₂ are the reactants

  CO₂ is the product of the reaction.

  • This reaction is called a combination reaction in which two species combines to give a product.
