The molecular geometry of a molecule with a core atom that has five areas of electron density and precisely one lone pair of electrons is called a disphenoidal or seesaw molecular geometry.
What is meant by disphenoidal or seesaw molecular geometry?
- Four bonds are made to an atom in the center of a disphenoidal or seesaw-shaped molecular structure, which has overall C2v structural symmetry. The fact that it resembles a playground seesaw is how it got the moniker "seesaw." Tetrahedral or, less frequently, square planar geometry is produced when four bonds to a center atom are present.
- The core atom of a molecule with a steric number of 5 and bonds to 4 additional elements and 1 lone pair is said to be in the seesaw geometry.

Answer:
There are four ways to find the charge of an element:
Use the periodic table. The usual charge of an element is common to its group. ...
Use a chart. ...
For a single atom, the charge is the number of protons minus the number of electrons.
Find the charge by balancing charge in a compound
Answer:
Granite
Explanation:
The specific heat capacity of a substance, which is denoted by "c", is the amount of heat required to raise the temperature of a particular mass of that substance by 1°C. It is calculated as follows:
c = Q ÷ m∆T
Where;
c = specific heat capacity
Q = amount of heat (J)
m = mass of substance
∆T = change in temperature.
According to this equation and explanation above, a low specific heat capacity means that the rate at which the temperature is raised is slow and vice versa. Hence, from this question, GRANITE with specific capacity of 0.790 J/gK will raise temperature the slowest.
Answer:
Option B is correct More hydrogen carbonate is formed
Explanation:
Step 1: Data given
The Principle of Le Chatelier says 'If the concentration of one of the reaction partners changes, the balance will shift to counteract that concentration change.
Step 2: When adding more H2O
For the equation CO2 + H2O --> H2CO3
If the H2O concentration is increased, the system will attempt to undo that change in concentration by shifting the balance to the right, and so the H2CO3 concentration will increase.
Option B is correct More hydrogen carbonate is formed
