Answer:
<u><em>Explain both aldehydes and ketones, the geometry around the carbon atom in the carbonyl group is trigon planar; the carbon atom exhibits sp2 hybridization. Two of the sp2 orbitals on the carbon atom in the carbonyl group are used to form σ bonds to the other carbon or hydrogen atoms in a molecule. The remaining sp2 hybrid orbital forms a σ bond to the oxygen atom. The hybridized p orbital on the carbon atom in the carbonyl group overlaps a p orbital on the oxygen atom to form the π bond in the double bond.ation .</em></u>
Answer:
(3rd option) Asexually reproduced offsprings have the same amount of genetic information as the parent, while sexually reproduced offsprings have half as much genetic information.
Explanation:
This is variation is caused as a result of both gamete production and fertilisation.
Explanation:
(a) As per the mole concept, one mole of any atom contains 
atoms or molecules, that is, Avogadro's number of atoms.
Therefore, 1 mole of 
= 
molecules
= 
molecules
1 mole of 
= molecules
= molecules
1 mole of 
= molecules
= molecules
Hence, there are equal number of molecules present in the given atoms.
(b) Mass of each given atom will be calculated as follows.
Mass = no. of moles × molar mass
As one molecule of contains 2 atoms of hydrogen.
So, mass of 1 mole of = 
= 2.016 g
mass of 1 mole of = 
= 31.996 g
mass of 1 mole of = 
= 37.996 g
Thus, we can conclude that has the greatest mass.
Answer:
