Kelvin is a temperature scale designed so that zero degrees K is defined as absolute zero (at absolute zero, a hypothetical temperature, all molecular movement stops - all actual temperatures are above absolute zero) and the size of one unit is the same as the size of one degree Celsius.
Answer:
Explanation:
A buffer pair consists of either
- A weak acid and its salt or
- A weak base and its salt
(a) Oxalic acid and sodium oxalate
Oxalic acid is an acid and lithium acid is a base. Together, they will neutralise each other and form the salt LiHC₂O₄.
A solution of LiHC₂O₄ is not a buffer.
The correct buffer pair is H₂C₂O₄ and LiHC₂O₄
(b) Carbonic acid and sodium carbonate
The carbonic acid and the sodium carbonate will neutralise each other and form the salt NaHCO₃.
A solution of NaHCO₃ is not a buffer.
The correct buffer pair is H₂CO₃ and NaHCO₃

Answer:
The answer to your question is below
Explanation:
Organic chemistry studies the compounds that have carbon, hydrogen, oxygen and other elements in their structure.
Carbohydrates are biomolecules that are composed of carbon, hydrogen, and oxygen that is why they are studied by organic chemistry.
Other biomolecules that are also studied by organic chemistry are Proteins, Lipids, and Vitamins.
