Answer:
The percentage of Lake Parsons which has evaporated since it became isolated is 68.24%.
Explanation:
The concentration of salt dissolved in Lake Parson = 21.0 g/L
= In 1 L of lake Parson water = 21.0 g of salt
The concentration of salt in several nearby non-isolated lakes = 6.67 g/L
The salt concentration in Lake Parsons before it became isolated = 6.67 g/L
In 1 L of lake water = 6.67 g of salt
If 1 L of lake Parson water has 6.67 g of salt. Then 21.0 grams of salt will be in ;
Water evaporated = 3.15 L - 1 L = 2.15 L
The percentage of Lake Parsons which has evaporated since it became isolated:
Under standard temperature and pressure, the optical activity of malic acid changes in the following ways:
- Wavelength of light
- Magnitude
- Temperature
- Concentration of solvent.
An optical activity is also referred to as optical rotation and it can be defined as the ability of a substance or chemical compound to rotate the plane of polarization of a beam of plane-polarized light that passes through it.
<h3>What is malic acid?</h3>Malic acid refers to an organic compound (dicarboxylic acid) that is typically made by all living organisms and its molecular formula is . Malic acid is considered to be one of the most satisfactory substances to be used when studying optical activity because of its chemical properties such as having single asymmetric carbon atoms.
Under standard temperature and pressure, the optical activity of malic acid changes in the following ways:
- Wavelength of light
- Magnitude
- Temperature
- Concentration of solvent.
