Azaleas’ are also known as the ‘Royalty of the Garden’, and are shrubs that bloom in from autumn to spring, depending on the variety.
Azaleas are either deciduous or evergreen, depending on the species, and generally like to grow under the shade of trees.
Azaleas are from the family ‘Ericaceae’, which is the family of heaths or heathers, and belong to the genus ‘Rhododendron’, which are a group of woody plants.
Azaleas grow up to 2.5 meters (8.2 feet) tall, although some only grow to half that height.
Azalea nectar and leaves are highly poisonous, and in the past, have been seen as a death threat if the flowers have been given in a black vase.
Places in Japan, Korea and the United States have festivals to celebrate azaleas.
Azaleas are mostly native to North America, and eastern parts of Asia, and the American species are generally deciduous, while the Asian species are generally evergreen.
Azalea flowers come in white, pink, mauve, purple, red, orange and yellow in colour, and the single varieties generally have 5 petals, but doubles can have up to 30.
Azaleas are popular garden plants, although many people do not know how to grow them properly, as they require specific growing conditions, which include the need for acidic soil.
Over 10,000 different cultivars of azaleas have been recorded and the plant and flowers are very similar to rhododendrons in appearance, so it is often difficult to tell them apart.
Answer is: D. Lewis base. Lewis acid is a chemical element, molecule or ion that contains an empty orbital which is capable of accepting an electron pair from a Lewis base. A Lewis base is element, molecule or ion that has a filled orbital and has electron pair which is not involved in bonding and can give it to Lewis acid. Lewis base is for example ammonia (NH3).
Los isómeros ópticos son dos compuestos que contienen el mismo número y tipo de átomos, y enlaces (es decir, la conectividad entre los átomos es la misma), y diferentes disposiciones espaciales de los átomos, pero que tienen imágenes especulares no superponibles. Cada estructura de imagen especular no superponible se denomina enantiómero.
The presence of the hydrogen between the ammonium and the carbonates characterizes the salt as an acid salt, so you could name it as acid ammonium carbonate or ammonium bicarbonate (similar to the sodium bicarbonate which is .
Triprotic acid is a class of Arrhenius acids that are capable of donating three protons per molecule when dissociating in aqueous solutions. So the chemical reaction as described in the question, at the third equivalence point, can be show as: H3R + 3NaOH ⇒ Na3R + 3H2O, where R is the counter ion of the triprotic acid. Therefore, the ratio between the reacted acid and base at the third equivalence point is 1:3. The moles of NaOH is 0.106M*0.0352L = 0.003731 mole. So the moles of H3R is 0.003731mole/3=0.001244mole. The molar mass of the acid can be calculated: 0.307g/0.001244mole=247 g/mol.
