The method of separation used was paper chromatography and the pigments were separated based on rates moved by each pigment. The extract was also separated based on the solubility of the various components and was found to contain green chlorophyll and yellow carotenoids.

All types of chromatography employ two different immiscible phases in contact with each other namely the mobile phase and the stationary phase.

Explain how an ionic compound forms from these elements.
grin007 [14]

Ionic compounds are formed by the complete transfer of electrons from more electronegative elements to less electronegative elements.

7. <u>Sodium Nitride (Na₃N)</u> is an ionic substance.

8. The ionic formula for <u>Lithium Oxide is Li₂O</u>

9. The <u>compound SrF₂</u>

10. Aluminum Sulfide is a chemical compound with the <u>formula Al₂S₃.</u>

An ionic compound is a chemical compound composed of ions held together via electrostatic forces termed ionic bonding. The compound is neutral standard but includes definitely charged ions known as cations and negatively charged ions known as anions.

An ionic compound is a chemical compound composed of ions held collectively by means of electrostatic forces termed ionic bonding. The compound is neutral normal however consists of positively charged ions known as cations and negatively charged ions referred to as anions. Ionic compounds incorporate ions and are held collectively via the attractive forces of most of the oppositely charged ions.

Nitrogen has two isotopes. One has an atomic mass of 14.003
Ilia_Sergeevich [38]

Answer:

d= 14.007 amu

Explanation:

Abundance of N¹⁴ = 99.63%

Abundance of N¹⁵ = 0.37%

Atomic mass of N¹⁴ = 14.003 amu

Atomic mass of N¹⁵ = 15.000 amu

Average atomic mass = ?

Solution:

Average atomic mass = (abundance of 1st isotope × its atomic mass) +(abundance of 2nd isotope × its atomic mass)  / 100

Average atomic mass = (14.003 × 99.63)+(15.000× 0.37) /100

Average atomic mass =  1395.12 + 5.55 / 100

Average atomic mass  = 1400.67/ 100

Average atomic mass = 14.007 amu.
