Answer:
Explanation:
Stereoisomers are two or more atoms that have the same bonding order of atoms but there is a difference spatial arrangement of the atoms in space.
A plane of symmetry divides a molecule into two equal halves.
A chiral stereoisomer are not superimposed on a mirror image , Hence they do not posses a plane of symmetry.
As a result to that. these non-superimposable mirror images are said to be Enantiomers.
However, a Fischer Projection emanates from a two - dimensional figure which is used for presenting a three - dimensional organic molecules.
From the given question;
Fischer projection for an enantiomer of 2-bromo-2,3-dihydroxypropanal with the bromine oriented horizontally to the left and the hydroxide group oriented horizontally to the right.
we can sketch the way the enantiomer of 2-bromo-2,3-dihydroxypropanal can be seen like the one shown below:
CH₂OH

The objective of this question is to drawn the perspective formula of the molecule.
So , from the attached file below; we can see the perspective formula of the molecule in a well structured 3-D format.
Answer:
a) A microstate is a snapshot of positions and speeds at a particular instant.
b) A thermodynamic state is a single possible arrangement of the positions and kinetic energies of the molecules.
c) A thermodynamic state is a set of conditions, usually temperature and pressure, that defines the properties of a bulk material.
d) A microstate is a single possibility for all the positions and kinetic energies of all the molecules in a sample.
e) A thermodynamic state is a set of conditions, usually temperature, volume and number of moles, that defines the properties of a bulk material.
Explanation:
A state of a system in thermodynamics give the properties that a material is been made up, these properties could be pressure, temperature, volumes and others , they are been called thermodynamic property
Microstates helps us to know how molecules is been arranged in single instant. Kinetics energy as well as position of molecules in a particular substance can be known in single instant.
Answer:
A saturated solution can become supersaturated when it is cooled. The solubility of solid solutes in liquid solvents increases as the solvent is warmed up. For example, you can dissolve more sugar in warm water as opposed to cold water.
Answer:
10.8amu
Explanation:
Given parameters:
Abundance of B - 10 = 20% = 0.2
Abundance of B - 11 = 80% = 0.8
Unknown:
Atomic mass of Boron = ?
Solution:
The atomic mass of Boron can be can be calculated using the expression below;
Atomic mass = (abundance of B - 10 x mass of isotope B - 10 ) +( abundance of B - 11 x mass of isotope B- 11)
Atomic mass = (0.2 x 10) + (0.8 x 11) = 2 + 8.8 = 10.8amu
