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.

Which of the following are physical characteristics of blood? 1. it is more viscous than water 2. its temperature is about 38ºC
yawa3891 [41]

Explanation:

A property which does not bring any change in chemical composition of a substance is known as physical property.

For example, blood is more viscous than water, its pH is slightly alkaline, its temperature is about 38^{o}C (100.4^{o}F)  .

On the other hand, a property which changes chemical composition of a substance is known as a chemical property.

For example, precipitation, reactivity, toxicity etc are chemical property.

Sometimes, the change in color of a substance can also occur due to a chemical change.

Thus, we can conclude that following are the physical characteristics of blood.

  • it is more viscous than water.
  • its temperature is about 38^{o}C (100.4^{o}F).
  • the pH is slightly alkaline.
  • it is about 8% of one’s total body weight.

It is easier to determine the electron configurations for the p-block elements in periods 1, 2, and 3 than to determine the elec
babymother [125]

Answer:

Their electrons are placed in a higher number of orbitals

Explanation:

  • Suppose a element be Ga .

The atomic no is 31

The configuration is given by

\\ \sf\longmapsto 1s^22s^22p^63ss^23p^63d^{10}4s^24p^1

Or

\\ \sf\longmapsto [Ar]3d^{10}4s^24p^1
