Derive an Ideal gas equation. Mention the terms involved in it.

Write how ideal gas equation is utilised to obtain combined gas law.

Solve the following.

A 20 L container holds 0.650 mol of He gas at 37°C at a pressure of 628.3 bar. What will be new pressure inside the container if the volume is reduced to 12 L. The temperature is increased to 177°C and 1.25 mol of additional He gas was added to it?

Give the test that is used to detect borate radical is qualitative analysis.

Ammonia is a good complexing agent. Explain.

A compound is prepared from the mineral colemanite by boiling it with a solution of sodium carbonate. It is a white crystalline solid and is used for inorganic qualitative analysis.

Write the reaction that explains its formation.

Shravani was performing an inorganic qualitative analysis of a salt. To an aqueous solution of that salt, she added silver nitrate. When a white precipitate was formed. On adding ammonium hydroxide to this, she obtained a clear solution. Comment on her observations and write the chemical reactions involved.
