The correct answer is Decomposition of calcium carbonate.

Key Points

• The decomposition of calcium carbonate (CaCO₃) results in the formation of calcium oxide (CaO) and carbon dioxide (CO₂).
• This reaction is represented by the equation: CaCO₃ → CaO + CO₂.
• The oxidation states of the elements do not change during this decomposition reaction, indicating it is not a redox reaction.
• In contrast, decomposition reactions that are redox reactions involve changes in the oxidation states of the participating elements.

Additional Information

• Decomposition Reactions
• A decomposition reaction is a type of chemical reaction in which a single compound breaks down into two or more simpler compounds or elements.
• These reactions often require an input of energy in the form of heat, light, or electricity.
• Examples include the decomposition of water into hydrogen and oxygen (2H₂O → 2H₂ + O₂) and the decomposition of potassium chlorate into potassium chloride and oxygen (2KClO₃ → 2KCl + 3O₂).
• Redox Reactions
• Redox reactions, or oxidation-reduction reactions, involve the transfer of electrons between two substances.
• Oxidation refers to the loss of electrons, while reduction refers to the gain of electrons.
• In a redox reaction, one substance is oxidized (loses electrons) and another is reduced (gains electrons).
• An example is the decomposition of sodium hydride (NaH), where NaH decomposes into sodium metal (Na) and hydrogen gas (H₂), with sodium being reduced and hydrogen being oxidized.
• Oxidation States
• The oxidation state (or number) of an element in a compound is a measure of the degree of oxidation of that element.
• It is defined as the charge an atom would have if all bonds were completely ionic.
• Changes in oxidation states during a reaction indicate a redox process.

The correct answer is jaundice

Key Points

• Jaundice (Icterus) is a condition where the skin, the whites of the eyes (sclera), and sometimes other tissues develop a yellow tint.
• This yellowing happens because of an excessive buildup of a substance called bilirubin in the blood.
• Bilirubin is a yellow pigment produced during the normal breakdown of red blood cells.

• Caused by increased destruction of red blood cells (hemolysis).
• Examples: Sickle cell anaemia, malaria.
• Hepatic (in the liver):
• Caused by liver diseases that impair its ability to process bilirubin.
• Examples: Hepatitis, cirrhosis, alcoholic liver disease.
• Post-hepatic (after the liver):
• Caused by an obstruction in bile ducts that prevents bilirubin from being excreted.
• Examples: Gallstones, tumors, bile duct strictures.

The correct answer is Inverse

Key Points

• Interest rates bear an inverse relationship with the demand for money.
• Opportunity costs of holding money will be high when interest rates are high;
• people are losing out on possible earnings that interest-bearing investments could have generated.
• When interest rates are high, the opportunity cost of holding money increases because people can earn more by investing their money rather than keeping it as cash.
• This leads to a lower demand for money for transactional and speculative purposes
• When interest rates are low, the opportunity cost of holding money is low.
• People prefer holding more money for transactions or precautionary needs because the benefit of investing it is minimal.
• This leads to a higher demand for money.
• The relationship can be visualized using the liquidity preference theory by John Maynard Keynes:
• The demand for money (liquidity preference) decreases as the interest rate increases, and vice versa.
