Explanation

Ribose and Deoxyribose

Are isomers

• Both are monosaccharides (simple sugars) with the same molecular formula: C₅H₁₀O₅.

• Deoxyribose differs from ribose by one less oxygen atom at the 2' carbon (hence "deoxy").

• They are structural isomers (same formula, different structure).

Explanation

• Lactic acid is a natural preservative found in fermented foods like yogurt, cheese, and sauerkraut.
• It's produced during the fermentation process when bacteria like Lactobacillus convert sugars into acid.

Explanation

• Heat is a form of energy that is transferred from one body to another due to a temperature difference.
• It is a type of kinetic energy that is transferred through the motion of particles.

Explanation

Explanation

When an aldehyde is oxidized, it typically converts to a carboxylic acid.

This reaction involves the addition of an oxygen atom to the aldehyde, changing the carbonyl group (C=O) at the end of the carbon chain into a carboxyl group (–COOH).

Explanation

• Heat is measured in Joules (J), which is the unit of energy.
• Heat is a form of energy transferred from one body to another due to a temperature difference.

Explanation

The rate at which nitrogen is used is 0.57 mol N2.L^-1.h^-1.

Explanation

The dual character of matter particles in motion was postulated by De Broglie. 

Louis de Broglie proposed the idea that particles like electrons could behave not only as particles but also as waves, a concept known as wave-particle duality

Explanation

The material used for bleaching paper pulp is sodium hypochlorite.

It acts as an effective bleaching agent.

It helping to remove color and impurities from the pulp.

Explanation
