EXAMPLE: What is the molarity of a solution made by dissolving 5.67 g of potassium chloride
in enough water to make 100.0 mL of solution?
This data gives a relationship between amount of solute and volume of solution: 5.67 g KCl /
100.0 mL. To find molarity we must convert grams KCl to moles KCl and mL solution to L:
5.67 g KCl 1 mol KCl 1000 mL 0.760 mol KCl
x x = or 0.760 M KCl
100.0 mL 74.6 g KCl L L
Solute is the term used for a substance being dissolved in a solution.
When two substances at different tempeartures como into contact, the substance that is at higher temperature will transfer energy, in the form of heat, to the substance that is at lower temperature, until their temperatures get equal.
In this case, if the two substances are isolated of the rest of the universe, the law of conservation of energy states tha the heat released by the substance initially at higher temperature is the same amount of heat gained by the substance originally at lower temperature.
Answer:
When a solution of silver nitrate is added to a solution of sodium chloride, the silver ions combine with the chloride ions to form a precipitate of silver chloride. The sodium and the nitrate ions are nonparticipating spectator ions. ... Like all equations, net ionic equations must be balanced.
