Write any four uses of CaCO3. Discuss the trends in atomic & physical properties of elements of Group-2. Write any four uses of LiAlH4.
Understand the Problem
The question is asking for specific uses of chemical compounds and trends related to elements in a particular group of the periodic table. This involves knowledge of chemistry concepts and applications.
Answer
CaCO3 uses: construction, antacid, filler, pH balance. Group 2 trends: decreasing atomic radii, increasing ionization, high reactivity. LiAlH4 uses: reducing agent, pyrotechnics, hydrogen storage, foaming agent.
For CaCO3: it's used in construction, as an antacid, a filler in products, and for pH balance in agriculture. Group 2 elements show decreasing atomic and ionic radii, increasing ionization energy, and high reactivity. LiAlH4 is used for reducing agents, in pyrotechnics, hydrogen storage, and as a foaming agent.
