Chromatography: Methods, Phases, and Separation Efficiency

Posted by on Dec 17, 2023 in Chemistry | 0 comments

Chromatography:

Physical method of separation. Compounds are distributed between stationary phase and mobile phase – the chromatographic process occurs as a result of repeated equilibration events during the movement of the sample components along the stationary phase bed. The separation occurs due to differences in their affinity for the stationary and mobile phases. As the components exit the system, a detector identifies them based on specific properties of the desired analytes.

Stationary Phase:

UNIT 3 AOS1

FEULS

Environmental Impacts- Petrodiesel–
Habitat and land destruction
Potential for oil spills as it needs to be transported Biodiesel–
Potentially carbon neutral, produces less CO2
Can be produced from waste products, Requires a lot of water to grow and wash the crops required to produce he oils, also biodegradable

Biofuel- Advantages–>


  Renewable – Net lower emissions of CO2  Disadvantages–>–
Production of CO2 – Lower energy content -Uses up arable land and resources for food crops 

Advantages

11.1

  • Genetics : scientific study of heredity
  • trait :  specific characteristic of an individual
  • hybrid : offspring of crosses between parents with different traits
  • genes : sequence of dna that determines a trait / factors that R   passed from parent 2 offspring
  • alleles : the different forms of a gene
  • principle of dominance: some alleles R dominant & others R recessive

11.2

  • Probability : the likelihood that a particular event will occur.
  • Homozygous : 2 identical alleles 4 a trait / TT , tt
  • Heterozygous

CHAPTER 12. PERSONALITY

1)Define personality:

An individual’s consistent patterns of feeling, thinking, and behaving.

2)Describe the processes that take place in the conscious, preconscious, and unconscious mind:

Unconscious mind:

·Memories outside awareness/not accessible

Preconscious mind:

·Thoughts just beneath surface

·Voluntary access

Conscious mind:

·Thoughts you are aware of

·Currently processing

3)Define and identify the functions of the id, ego, and superego:

Id:

·Primitive impulses, unconscious

·Pleasure

Substances can exist in each of these three states:

– solid

– liquid

– gas

• depending on the temperature and pressure.


The solid state

• Solids have:
• definite shape and definite volume • high density
• small compressibility
• very small thermal expansion

• Solid molecules are packed closely and rigidly together, so that they cannot easily slide past each other (potential energy dominates).


The liquid state

  • Liquids have:
    • indefinite shape and definite volume • high density
    •
