🗑
|
||||
| A #4 | Acids react with bases to produce salt + water
🗑
|
||||
| A #5 | Acid solution, conduct electric current so must be electrolytes.
🗑
|
||||
| Standard molar volume | Volume occupied by one mole of an ideal gas at STP, + 22.4
🗑
|
||||
| Avagadro's law | Equal volumes of gases at the same temperature and pressure contain equal numbers of molecules
🗑
|
||||
| COmbine gas law | P1V1 = P2V2
____________
T1 T2
🗑
|
||||

----------------
1Kg of solute
🗑
|
||||
| Net ionic equation | only those compounds and ions that undergo a chemical change in a reaction in an aqeous solution
🗑
|
||||
| Spectators | ions that do not take part in a chemical equation and are found in solution both before and after reaction
🗑
|
||||
| Percipitate | Solids formed in a liquid
🗑
|
||||

🗑
|
||||
| immiscible | Liquids that are not soluable in each other
🗑
|
||||
| Colloids | larger can see the light being reflected off. Particles are not at fundamental state but are small enough to remain suspended indefinetly
🗑
|
||||
| Entropy | Measure of randomness or disorder of a system
🗑
|
||||
| Why reactions take place spontaneously | 1.Energy chemical reaction will occur if you are moving towards lower amounts of enrgy. Substances that have Hf will occur more than the T. greater enrgy change the more stable or unstable it will be.
🗑
|
||||
| SPontaneous reactions #2 | Entropy- the measure of degree of randomness or the level of disorder everything in nature moves to higher levels of entropy.
🗑
|
||||

🗑
|
||||
| Property of Bases #1 | Have bitter taster like soap.
🗑
|
||||
| B #2 | If you take strong base and mix animal fat and you can make soup.
🗑
|
||||
