STP

STP is the standard temperature and pressure. For gases and this unit we learned that the temperature at STP is a temperature of 0 degrees Celsius and and a pressure of 1 atmosphere. This information is necessary when other parts of the gas, such as the moles, are wanted to be discovered at STP.
 All of the information listed must be known/used for the equations mentioned in my earlier posts.

Here is are two links that explain this in more depth:

Another thing that is important to know, is the units necessary to complete the equations that you use:

Air Bag Lab

This week we will be completing a lab where we have to create a makeshift air bag that doesn't have too much air nor too little. We will have to use both stoichiometry as well as the molar volume of gas to design a plan for the air bag. 

Here is a link that describes the concept of an air bag: http://auto.howstuffworks.com/car-driving-safety/safety-regulatory-devices/airbag.htm

In air bags sodium metal and nitrogen gas are created, here is the equation that reflects what takes place: 

In the lab carbon dioxide is created, here is the equation that reflects what takes place: 

Charles, Boyle, and Avagadro

So far, we have learned three different gas laws. One is Charles Law, one is Boyle's Law, and the last one is Avagadro's Law. The equation for each law derives from the ideal gas law equation, it is just oriented differently:

Each of the three gas laws differs because there are different things that remain constant in them all. Here is a link that more throughly explains this concept: http://chemwiki.ucdavis.edu/Wikitexts/Solano_Community_College/Chem_160/Chapter_05%3A_Gases/5.02_The_Gas_Laws_of_Boyle,_Charles,_and_Avogadro

Ideal Gas Law

All of the gases that we will work with in Chemistry this year will be ideal gases. In order to quality as an ideal gas there are a few stipulations. Here is a link that should help you understand what these exactly are: http://hyperphysics.phy-astr.gsu.edu/hbase/kinetic/idegas.html

The equation that is shown in the picture below is the equation used for solving ideal gas law problems

Each letter in the equation means something different. Here is what each letter stands for (from left to right):

• Pressure
• Volume
• Number of Moles
• Universal Gas constant
• Temperature

Here is another link that should help you better understand how and when to use the equation: http://chemwiki.ucdavis.edu/Core/Physical_Chemistry/Physical_Properties_of_Matter/States_of_Matter/Gases/Gas_Laws/The_Ideal_Gas_Law
