Explanation

On further reaction, the oxidation of a primary alcohol initially forms an aldehyde, which is then further oxidized to a carboxylic acid.

The specific product obtained (aldehyde or carboxylic acid) depends on the strength of the oxidizing agent and reaction conditions. 

Explanation

Isotope of Hydrogen:

Tritium (symbol ³H) is one of the three isotopes of hydrogen. 

Composition:

Its nucleus contains one proton and two neutrons. 

Instability:

The nucleus is unstable and decays by beta decay into helium-3, a stable isotope of helium. 

Radioactivity:

It is a radioactive material with a half-life of approximately 12.3 years. 

Production:

Tritium is produced naturally in the upper atmosphere by cosmic rays and also as a byproduct in nuclear reactors and nuclear weapons.

Explanation

Explanation

The new fringe width will be four times the original fringe width (quadrupled)

Because the formula for fringe width is directly proportional to the screen distance (D) and inversely proportional to the slit separation (d).

When the slit separation is halved (d/2) and the screen distance is doubled (2D), the fringe width increases by a factor of (2D / (d/2)) = 4. 

Explanation

After successful implantation in the uterus or an ovary (in the case of an ectopic pregnancy),

The embryo's trophoblast tissue begins to secrete human chorionic gonadotropin (hCG).

This hormone is essential because it maintains the corpus luteum, which continues to produce progesterone.

Progesterone is critical for maintaining the uterine lining and thus supporting the pregnancy. 

Explanation

Soda lime is a mixture of sodium hydroxide (NaOH) and calcium oxide (CaO)

It is commonly used in decarboxylation reactions to remove the carboxyl group from a carboxylic acid molecule. 

Explanation

Lithium aluminium hydride (LiAlH₄) is a strong reducing agent.

It reduces carboxylic acids to primary alcohols effectively.

Explanation

The most abundant polymer on Earth is cellulose

Composition:

Cellulose is a polymer made up of glucose units. 

Natural Occurrence:

It is the primary structural component of plant cell walls, giving plants their rigidity and strength. 

Abundance:

It is the most abundant organic polymer on Earth, found extensively in plant life. 

Examples:

Cotton is a very pure form of cellulose, with a cellulose content of around 90%, while wood contains about 40-50%. 

Explanation

Explanation

A substance that breaks just after the elastic limit is reached is called a brittle material.

Brittle materials, such as glass and high-carbon steel, undergo very little plastic deformation and fracture soon after exceeding their elastic limit, with no significant elongation or bending.
