D. a substance that is dissolving
What is A. a substance that something disolves in?
unsaturated solutions
What are solutions that contain less than the maximum amount of solute that is capable of being dissolved.
The kind of electrolytes that completely ionize when dissolved, and no neutral molecules are formed in solution.
What are strong electrolytes?
Weak electrolytes
What are electrolytes where only a fraction of the molecules ionize when dissolved in water?
Amazon only sold this kind of product
What are books?
What is a solute?
A gesture given to authority
A solid that is formed from a chemical reaction
Mixing mentos and diet coke
A substance that is being dissolved
What is 4. a substance that is being dissolved?
What is entropy?
What is a measure of molecular randomness or disorder
What happens to the solubility when the temperature decreases?
What is the solubility decreases which causes an exothermic reactions. (exothermic=releasing heat to surroundings)
The formula to find the molar concentration of a solution
What is M= Moles of solute / liters of solution?
the name of Princess Leia's home planet in Star Wars
Alderaan
What is a solution?
The answer to a math problem
A homogeneous mixture consisting of a solute dissolved in a solvent.
A heterogeneous mixture consisting of a solute dissolved in a solvent
Either a homogeneous or heterogeneous mixture consisting of a solute dissolved in a solvent
What is 2, A homogeneous mixture consisting of a solute dissolved in a solvent.
What is an electrolyte?
Gatorade
A substance that dissolves in water or other polar solvent to produce ions and a solution that conducts electricity
A solution that turns covalent molecules into ionic molecules
A concentrated form of a solution
What is A substance that dissolves in water or other polar solvent to produce ions and a solution that conducts electricity?
What are the factors affecting saturation?
What are temperature, agitation (stirring) and surface area
What is Henry’s Law
A. increase pressure, more gas dissolves**
B. Decrease pressure, more gas dissolves
C. Henry.....insert law here_______
D. All of the above
What is an increase in pressure the more gas dissolves and with a decrease in pressure the less gas dissolves?
What is decompression sickness?
What are injuries caused by a rapid decrease in the pressure that surrounds you?
When you scuba dive with compressed air, you take in extra oxygen and nitrogen. Your body uses the oxygen, but the nitrogen is dissolved into your blood, where it remains during your dive. As you swim back toward the surface after a deep dive, the water pressure around you decreases.
What is a saturated solution?
What is a solution with solute that dissolves until it is unable to dissolve anymore. If you add anymore solute, it will not dissolve. The water molecules are attracted to the solute atoms and molecules more strongly than they are attracted to each other. They surround the solute molecules, and as they do, the solute gradually disintegrates.
The definition of electrolytes
What are substances that give ions when dissolved in water?
They can be divided into acids, bases, and salts, because they all give ions when dissolved in water.
What is solubility increases which causes an endothermic reactions? (endothermic = accompanied by or requiring the absorption of heat.)
Divide mass of solute in grams by it’s molar mass in g/mol
What is finding the moles of a solute?
The math of chemistry. It helps us figure out how much of each substance we need in a chemical reaction and how much product we can expect to make.
Supersaturated solution
What is a solution that contains more than the maximum amount of solute that is capable of being dissolved at a given temperature. (When a seed crystal is added to the solution a supersaturated solution can recrystallize.) rock candy! You have to heat the water close to the boiling point. When the water gets this hot, the water molecules have more freedom to move around, and there is more space for solute molecules between them. You can keep stirring in salt, sugar or any other solute, and it will continue to dissolve, even though the saturation point has been reached. Take away the heat and let the solution gradually cool, and the solute will remain dissolved, at least for a time. This is, in essence, the supersaturated definition. A supersaturated solution is highly unstable, and strange things can happen.
True or False- Electrolyte solutions conduct electricity
What is true?
These solutions conduct electricity due to the mobility of the positive and negative ions.
