Explanation:
Crotonic acid : C₃H₅CO₂H
C₃H₅CO₂H ⇄ C₃H₅CO₂⁻ + H⁺
C O O
where : C = C ( 1 - ∝ ) , O = C∝
also: Ka = C∝² / ( 1 - ∝ ) ---- ( 1 )
<em>From Alexa data resource : </em>
Pka = 4.69 , [ Ka = 2.04 * 10^-5 = C∝² / ( 1 - ∝ ) ]
back to equation 1
2.04 * 10^-5 = [ ( 0.63 * 10^-3 ) * ∝² / ( 1 - ∝ ) ] ----- ( 2 )
∴ ∝² / ( 1 - ∝ ) = 3.24 * 10⁻²
Resolving equation above
∝ = 0.1645 = 16.45%
The planets and the sun form the solar system. The sun is an enormous star. The planets move around the sun. Mercury,Venus,earth, and Mars are the four small rocky planets. Jupiter, Saturn, Uranus, and Neptune are the four giant gas planets
Answer:
When corals are stressed by changes in conditions such as temperature, light, or nutrients, they expel the symbiotic algae living in their tissues, causing them to turn completely white. Warmer water temperatures can result in coral bleaching.
<span>The type of map that shows the type and age of
rocks in an area is called a Geologic Map. A geologic map is a special-purpose
map that represents the distribution of diverse types of rocks, as well as
locations of different geologic structures such as faults and folds. This map
is the main source of information for various aspects of land-use planning,
especially in the placement of transportation systems and buildings. Although
they are typically depicted as two-dimensional, they can also be illustrated in
its third or fourth dimension depending on the type of information needed to be
taken. </span>
