If water were a linear (not bent) molecule like co2, electrostatic interactions between water molecules would be much weaker. wh
Ksenya-84 [330]

Answer;

The partial negative charge on oxygen would stick out less and be less able to participate in hydrogen bonding.

Explanation;

Water is a polar molecule because the electrons are not shared equally, they're closer to the oxygen atom than the hydrogen.

-Normally, the water molecule is a bent shape because of the pair of lone electrons - they repulse each other and exert a compression to the hydrogen atoms at a slight 104º angle. It is a bent molecular geometry that results from tetrahedral electron pair geometry.

-The 2 lone electron pairs exerts a little extra repulsion on the two bonding hydrogen atoms to create a slight compression to a 104 degrees bond angle. Therefore, the water molecule is bent molecular geometry because the lone electron pairs.

Thus, If water were a linear molecule like co2, electrostatic interactions between water molecules would be much weaker, then the partial negative charge on oxygen would stick out less and be less able to participate in hydrogen bonding.

What is the physical process whereby atoms or molecules tend to move from an area of higher concentration or pressure to an area
34kurt

Diffusion is the physical process whereby atoms or molecules tend to move from an area of higher concentration or pressure to an area of lower concentration or pressure.

In the field of science, diffusion can be described as a process in which molecules move along the concentration gradient i,e from a region of higher concentration to a region of lower concentration.

The process of diffusion is extremely useful in many everyday living conditions. For example, it is due to diffusion that carbon dioxide and oxygen are exchanged between the lungs and the blood. Diffusion of water, salts, and water is an important process that occurs in the kidneys.

We can divide diffusion into two main types which are simple diffusion and facilitated diffusion. Simple diffusion occurs without any carrier molecule. On the other hand, facilitated diffusion occurs with aid of a carrier molecule.

What is the rule when "ao" or "oo" are together when naming covalent bonds
Gnoma [55]

They are converted into a single “o” when "ao" or "oo" are together when naming covalent bonds.

<h3>What is a covalent bond?</h3>

A covalent bond consists of the mutual sharing of one or more pairs of electrons between two atoms.

Sometimes, while naming the chemical compounds, a problem arises when compounds with “ao” and “oo” are written with -ide name. Conventionally, they are converted into a single “o”.

For example, the “ao” in the dichlorine hept-ao-xide (Cl_2O_7). This “ao” in the Cl_2O_7 can be converted into “o”. As the result, the correct name of this compound would be dichlorine hept-o-xide.

Hence, they are converted into a single “o” when "ao" or "oo" are together when naming covalent bonds.
