Mechanical waves are classified according to transverse waves.
Explanation:
The number of units of the molecular formula P2O10 is
<h2>........…Phosphorus pentoxide…………..</h2>
The answers is 54 because 27 protons times theses nuts = 54
Solids: wood, plastic, metals
Liquids: water (H2O), soap, juice, milk
Gases: Air, water vapour (H2O), carbon dioxide (CO2)
An element: gold, silver, aluminum, copper, nickel, iron, nitrogen in the air
A compound: salt (NaCl), carbon dioxide (CO2)
A homogenous mixture: air, water with sugar or salt dissolved in it
A heterogeneous mixture: orange juice with pulp, cereal in milk
Pure substances: diamond, water, salt, baking soda, sugar
The given compound 3-chloro-3-methylpentane is not optically active .
Because this compound have plane of symmetry (POS) and center of symmetry (COS) i.e. have di-symmetry . And also forms superimposable mirror image . the compound is not optically active .
It does not have chiral center.
Here the carbon atom has only 3 distinct groups i.e. ethyl , chlorine , methyl .
<h3>What is di-symmetry?</h3>
Di-symmetry is that which have no center of symmetry and plane of symmetry and alternate axis of symmetry .
<h3>Chiral center :</h3>
Have Sp3 hybridized center (4sigma bond ) .
4 distinct group is attached to the chiral atom. form non -superimposable mirror image .
<h3>What is optical isomerism ?</h3>
Same molecular formula and same structural formula . also have same physical and chemical properties .
They differ in their behavior towards plane polarized light (ppl) .
