Write any four uses of CaCO3. Discuss the trends in atomic and physical properties of elements of Group-2. Write any four uses of LiAlH4.
Understand the Problem
The question consists of multiple parts related to chemistry, specifically asking for uses of certain compounds, trends in group elements, and uses of a specific chemical.
Answer
CaCO3: construction, antacid, supplement, firming agent. Group-2: size ↑, ionization energy ↓, density ↑. LiAlH4: reducing aldehydes, ketones, esters, acids.
Uses of CaCO3: Used in construction as a building material, an antacid, a food supplement, and a food firming agent. Group-2 trends: Atomic size increases down the group, ionization energy decreases, and density increases. Uses of LiAlH4: Reducing agent for aldehydes, ketones, esters, and carboxylic acids.
Answer for screen readers
Uses of CaCO3: Used in construction as a building material, an antacid, a food supplement, and a food firming agent. Group-2 trends: Atomic size increases down the group, ionization energy decreases, and density increases. Uses of LiAlH4: Reducing agent for aldehydes, ketones, esters, and carboxylic acids.
More Information
Calcium carbonate is fundamental in preventing heartburn and providing dietary calcium. LiAlH4's ability to act as a strong reducing agent makes it essential in organic chemistry.
Tips
Be cautious with trends predicting: remember, down Group-2, atomic radii increase but reactivity varies.
