Gas Variables
In the equation PV=nRT, P represents what and is measured in?
Pressure in atm(or kPa or mg of Hg)
A solution that has more solute than it can hold and has undissolved solute will be considered.
Saturated
In the equation for determining concentration volume of solution must be measured in?
L (liters)
More, less
In the book the Hunger Games by Suzanne Collins, a young girl named Katniss Everdeen is chosen in as tribute for a game in which she must fight to the death. She and contestants from 14 other districts compete for glory and wealth for their district.
There was only 12 districts in the first Hunger Games book and the 13th was introduced later but there were never 14.
In the equation PV=nRT, V represents what? What is it measured in?
Solubility of a solute is measured at what point for a solute solvent mixture.
Saturation Point
How do you convert from mL to L.
Divide the amount of mL by 1000 or move the decimal 3 places to the left.
Concentrations (of stock and of diluted solution)
In the movie Star Wars IV: A New Hope. Farm boy Luke Skywalker and Jedi Master Yoda set off to rescue Princess Leia after receiving a distress message from two droids. They hire smuggler Han Solo and Chewbacca to help them on their way. The group set off together to rescue the Princess from the Death Star.
It was Ben Kenobi, Yoda did not appear until the next film.
In the equation PV=nRT, n represents what and is measured in what?
Moles of gas in mols
As the amount of solvent increases the solubility of a solute?
Stays the same
The equation for concentration is. What is in the blank?
_/(Volume of Solution)=Concentration
Moles or Solute
Ender's Game is a 1985 sci-fi novel by American author Orson Scott Card. Set in Earth's future, the novel presents an imperiled humankind after two conflicts with an insectoid alien species known as the Arachnids. In preparation for an anticipated third invasion, Earth's international military force recruits young children, including the novel's protagonist, Andrew "Ender" Wiggin, to be trained as elite officers. The children learn military strategy and leadership by playing increasingly difficult war games, including some in zero gravity, where Ender's tactical genius is revealed.
The name of the aliens is not Arachnids but Formics, this is the name of the insectoid aliens in Starship Troopers.
In the equation PV=nRT, what does T represent and what is it measured in?
Temperature in K (kelvin)
As the temperature of a solution increase the solubility a solute will?
Increase* (unless the solute is a gas)
The unit for concentration is?
M (Molarity)
The more concentrated solution that you are diluting is referred to as the?
Stock Solution
The hit game Minecraft is one of the best selling games of all times. Its blocky world and and ability to build offers endless possibilities for players. Following its initial release in 2009 there has been many content updates. Adding a variety of features including new dimensions like the Nether, bosses like the Wither Dragon, and new creatures like bees and bunnies.
It's not the Wither Dragon its the Ender Dragon.
In the equation PV=nRT, what does R represent and what is its value?
The Gas Constant, 0.08206 if using atm (8.314 if using kPa)
Solubility values are standard recorded as mass of solute at saturation over how much water?
100g
Given the information 25g of NaCl and 165mL of solution, could you plug these numbers directly into the concentration equation?
No, you need to convert your mass of your solute to moles and volume in mL to L.
When making a dilution what two things are we combining?
Stock solution and pure water.
The Thing was the title of the 2011 sci-fi horror movie which was a prequel to the original 1982 film by the same title. This original idea by John Carpenter features a creature that can take the form of any person in the group. The group attempts to figure out who is actually the creature before being taken out one by one.
The Thing is not an original idea by John Carpenter, it is actually based on the earlier movie 'The thing from another planet' which is based on the novella 'Who goes there?'
