Question

PICK OUT THE ODD ONE: 1. Water, Salt, Sugar, Sulphur 2. Aluminum, Gold, Sulphur, Iron​

Answer 1

The odd ones are - 1) Water , and , 2) Sulphur.

• In the first set, there are four substances, which are -

1. Water
2. Salt
3. Sugar
4. Sulphur

• Now, at the room temperature salt,sugar and sulphur are solids.
• Whereas, water is liquid at the room temperature.
• That's why, water is the odd one in the first set.

• In the second set there are four elements, which are -

1. Aluminium
2. Gold
3. Sulphur
4. Iron

• Now, aluminium,gold and iron are metals.
• Whereas, sulphur is a non-metal.
• That's why, sulphur is the odd one in the second set.

Answer 2

THE ODD ONE: 1. Water,Sulphur

Explanation:

• Water: It is a gaseous, liquid, and solid material that is made up of the chemical components hydrogen and oxygen. It is one among the most abundant and necessary chemicals.  
• Salt: It contains vital minerals that work as electrolytes in the body. Fluid balance, nerve transmission, and muscle function are all aided by them.
• Sugar,Sulphur:The sulphur residues that are found in traditionally treated sugars are absent in sulphurfree sugar. Sulphur as a food additive has been scientifically established to increase the risk of allergies (asthma) in people who are vulnerable to it.
• Aluminum, Gold: A gold aluminium intermetallic is a gold–aluminium intermetallic compound that forms when the two metals come into contact  With a melting point of 1060 °C (see phase diagram), similar to that of pure gold, AuAl2 is the most thermally stable of the Au–Al intermetallic compounds.
• Sulphur, Iron​:It's a brand-new chemical with qualities that aren't seen in Fe or S. As a result, heating a powdered iron and sulphur mixture results in a chemical change.
