This term refers to a homogeneous mixture of two or more substances.
What is a solution?
Molarity is defined as moles of solute per this volume of solution.
What is a liter?
Silver tarnishing is an example of this change
What is a chemical change?
The process by which sweat cools the body as it evaporates is an example of this phase change.
What is vaporization?
Provide the formula for density?
What is density= mass/Volume
The substance that dissolves in a solution is called this.
What is the solute?
What does Molarity measure?
The concentration in a solution
Solid CO2 sublimes into gas.This illustrates this property
What is a physical property?
Dry ice “disappearing” into a gas is an example of this direct solid-to-gas change.
What is sublimation?
Provide the melting point of boron
What is 2348 K?
When a lot of solute is present compared to the solvent, it reaches this level of saturation.
What is concentrated?
If 0.25 moles of HCl are dissolved to make 500 mL of solution, what is the molarity?
What is 0.50 M?
Solubility measures the ability of a solute to dissolve in a solvent. This is an example of this property
What is a physical property?
Frost forming on a cold window occurs when water vapor skips the liquid phase and turns directly into a solid.
What is deposition?
What does Joules measure?
Energy, work, quantity of heat
Measuring this would provide you with the concentration of a solution.
What is Molarity?
