The last math procedure you will ever need for chemistry word problems.

Today in AREA154:

• Training 4 Section 1 – Make sure you have this done today and signed off!
  -=-
• “SLiCED Math” Learn the last math procedure you will ever really need. You’ll watch the demonstration in class and then do the practice problems… because you know you can’t get good at something unless you practice!!
  -=-
• Get the first FOUR problems on the work sheet completed and checked for correctness.
  -=-
• GOAL today: Learn the “SLiCED” math process.
  STAGE – Draw out the “stage” to organize your numbers
  LIST – List your known value first then list the conversion factor
  CROSS-CANCEL – The units you want to eliminate are canceled
  EXECUTE – Multiply across the top and the bottom
  DIVIDE – Divide the numerator by the denominator

  BOOM! When you have the units the question asks for, you’re done!

Pools might be one of the most important and easily accessible store houses for water. One 5,000 gallon pool could supply a house of 5 people for 3 years! But it’s not usable currently, well, outside of the acid rain, it has a lot of other stuff in it as well.

Today in AREA154:

• Training 4 Section 1 Your last simulation will come in handy now as you will be doing the exact same thing but with a much larger volume of water. Just remember, it’s not about the size of the water volume… those are just numbers. It’s the process you need to worry about.
  -=-
• The first key is to write the data table down into your notes. After the process is explained, you might want to watch the Dir. Briefing again if you forget something.
  -=-
• This is a timed activity. You have 20 minutes.
  Finish in less than 15 min = 10+2
  Finish between 15 -20 min = 10
  Finish between 20 – 22 min = 8
  Finish between 22 – 26 min = 6
  Finish past 26 min = 5
  -=-
• GOAL today: Finish T4S1 and have it signed off.

Lots of agents will ask this question once the solution turns purple-blue. You could theoretically drink it, but it will taste horrible and salty. Why? It tastes this way because of the products of the acid and base reaction. These types of reactions will always form the same kinds of products (at the very least): A salt and a water.

Today in AREA154:

• Finish the TANK simulation. How much baking soda would be needed to neutralize the whole tank? Remember that? All we need to know is how many grams of NaHCO3 we need per milliliter and we’re golden.
  -=-
• Think you can do it again? Yup… now it’s an entire pool! Training 4 Section 1
• GOAL today: Finish the 500 Liter tank simulation, start T4S1.

Ready to prove what you know!? You’ll be taking the SRT #3 today. You know where to find it.

Today in AREA154:

• SRT #3 Go to the page where you see the training, the link is at the bottom.
  -=-
• GOAL today: Get 80% or better! Don’t stop until you do! Review the guide below before you start.

OH, and there’s an SRT Tomorrow, so here’s the study guide:

• Know what the pH of perfectly neutral water would be
• Know the range of the entire pH scale
• Know which part of the pH scale is acidic and which side is basic
• What is the specific atom that is responsible for a solution being acidic?
• What chemical species is the opposite of an H+ ion?
• When H+ and OH- react together what is the product?
• What is the criteria for a strong acid?
• What is the criteria for a strong base?
• Is the solution is acidic what color would our indicator turn?
• What was the name of the vegetable that was used to make the indicator?
• What was the name of the gas that bubbled out of the solution when you were neutralizing the rain water acid?
• What was the name of the based used in our rain water neutralization?
• What are the products that form after EVERY acid and base neutralization reaction?
• What is the name of the volcanic gas that makes the deadly acid rain?
• Know what “MOLAR MASS” is and how to find the molar mass of an atom or compound.

So, recall that 500L tank? And we took a sample of it out to neutralize. The goal was to know how much to use to neutralize the entire tank! We have to be careful… we can’t mess this up.

Today in AREA154:

• Neutralize This: Check out the back screen because we’ll be using this as a template to collect data and figure out how many grams of sodium bicarbonate (baking soda) would be needed to neutralize the 500L tank.
  -=-
• GOAL today: Successfully set up and experimentally conclude how many grams of sodium bicarbonate would be needed to neutralize a 500L tank of acid rain water.
