A molecule contains four bonded pairs of electrons and zero lone pairs. What is the name of the molecular geometry?
1 answer:
Answer: Option (d) is the correct answer.
Explanation:
A tetarhedral geometry is the geometry which includes four atoms bonded to the central atom and it does not contain any lone pair of electron.
For example, has tetrahedral geometry.
Thus, we can conclude that a molecule which contains four bonded pairs of electrons and zero lone pairs. The name of the molecular geometry is tetrahedral.

= V
Therefore, we can conclude that value of potential difference is V.
Answer : The mathematical equation used when solving calorimetry problems is:
Explanation :
Calorimetry : It is determining the changes in the energy of a system by measuring the heat transferred with surroundings.
Formula used :
where,
c = specific heat capacity of calorimeter
m = mass of a substance
q = heat required
= change in temperature of substance
