Grams of water that need to be evaporated to give saturated solution of KNO 3 in water at 20 ° C have to be determined. Concept Introduction: Solution is used for description of any system that consists of mixture of substances dissolved in another substance. It has two components, solute and solvent. Component that is present in less quantity and is dissolved in another component is called solute while the one that dissolves solute in it and is present in more amounts is known as solvent. Types of solutions: 1. Saturated solution When maximum amount of solute is dissolved in solvent, solution becomes saturated. Additional solute becomes undissolved in such types of solutions. 2. Unsaturated solution When solute less than maximum capacity is added to solvent, unsaturated solution is formed. Additional solute is dissolved in such solution. 3. Supersaturated solution. Such types of solutions consist of extra amount of solute than that can be actually dissolved in solvent.

Interpretation Introduction

Interpretation:

Grams of water that need to be evaporated to give saturated solution of KNO3 in water at 20 °C have to be determined.

Concept Introduction:

Solution is used for description of any system that consists of mixture of substances dissolved in another substance. It has two components, solute and solvent. Component that is present in less quantity and is dissolved in another component is called solute while the one that dissolves solute in it and is present in more amounts is known as solvent.

Types of solutions:

1. Saturated solution

When maximum amount of solute is dissolved in solvent, solution becomes saturated. Additional solute becomes undissolved in such types of solutions.

2. Unsaturated solution

When solute less than maximum capacity is added to solvent, unsaturated solution is formed. Additional solute is dissolved in such solution.

3. Supersaturated solution.

Such types of solutions consist of extra amount of solute than that can be actually dissolved in solvent.

PLEASE READ!!! I DONT WANT EXAMPLES, I DONT WANT WORDS OR PARAGRAPHS FOR THE MECHANISM!!! THANKS First image: QUESTION 6. I have to show, with ARROWS and STRUCTURES, the mechanism of the reaction at the bottom. Also I have to show by mecanism why the reaction wouldn't work if the alcohol was primary. I also tried to draw the mechanism, tell me what to change. Please note that its an AMIDE thats formed not an AMINE the nitrogen has ONE hydrogen and one Phenyl-C-Phenyl. I already asked for this mechanism and got as a final product ...-NH2 not whats shown on the picture, thank you Ths second part. QUESTION 3. I just need a way to synthesize the lactone A, I already started please continue from where I left it Second image: I simply need the products, substrates or reagents, thank you
