Answer:
The mole was previously defined as the number of atoms determined experimentally to be found in 12 grams of carbon-12. The number of units in a mole also bears the name Avogadro's number, or Avogadro's constant, in honour of the Italian physicist Amedeo Avogadro.

The period of the life cycle during which positive nitrogen balance is most likely to occur is childhood.
<h3>What is nitrogen balance?</h3>
The term nitrogen balance refers to the fact that there is a balance between the intake and the loss of nitrogen. The intake of nitrogen occurs when a person takes in food that contain proteins which are a rich source of nitrogen in the body and helps in the process of the build up of the cells in the body.

Answer: OA is a balanced equation.
Explanation: For an equation to be balanced, the number of atoms and the total charge of each element in the reaction, of the product and reactant side must be the same.
Considering OA; 6 atoms of nitrogen is present in the reactant side. Shifting to the product side, 6 atoms of nitrogen is also present. Taking the other element in the reaction into account, the number of atoms of each element balances on both sides.
For the following alkyne structure, the hybridization of each carbon in the molecule is C1 = Sp3, C2=Sp3, C3=Sp, C4=Sp, C5= Sp3
Bond angle=
1)C1-C2-C3= 109 degree 28
2)C2-C3-C4=180 degree
3)C3-C4-C5= 180 degrees
Effective molecular charge order= S> Si> AI> Mg
What is hybridization?
In chemistry, orbital hybridization (or hybridization) is the concept of mixing atomic orbitals to form new hybrid orbitals (having different energies, shapes, etc. than the component atomic orbitals) suitable for electron pairing. Yes, they form chemical bonds through valence bond formation.
Hybridization is defined as the concept of mixing two atomic orbitals to create a new type of hybrid orbital. This mixing usually results in the formation of hybrid orbitals with very different energies, shapes, etc.
