1 scoop of powder & 500 ml of water
1 scoop of powder & 1000 ml of water
2 scoops of powder & 500 ml of water
2 scoops of powder & 1000 ml of water
This is the one with the highest concentration.
What is 2 scoops of powder & 500 ml of water?
200
These are the substances we ended up with after our chemical reactions.
What are products?

I have a mixture of pebbles, flour & Epsom salts. I want to separate pebbles first, then flour, then Epsom salts. After adding 50 ml of water, this is the order of methods used to separate the mixture.
What is screening, filtering, evaporation?

Salt, Sugar, Sand, Snowflakes - This is the one that DOES NOT appear as a crystal.
What is sand?

I have a saturated solution that is made with 40 grams of citric acid. This is the amount of citric acid I could dissolve if I made the solution with HOT water.
What is about 80 grams?

These are the 2 ways we changed the concentration of our Kool Aid solutions.
What is add more powder AND add more water?

I add a mystery material to a cup of clear liquid. This is what I will SEE if a chemical reaction has taken place.
What is gas formation shown with fizzing or bubbles?

These all the 4 weighs we tested the concentration of different solutions.
What are tasting, smelling, looking at the color, weighing them?

True or False: When a material reaches its melting point, a chemical reaction takes place.
What is FALSE? The material changes from a solid to a liquid, but a chemical change does not occur.
500
This is the difference between a mixture and a solution.
What is the material dissolves in a solution?
500
These are the 2 types of salt we used in our labs.
What is Kosher salt & Epsom salts?
500
This is what will always be the same if I have two saturated solutions made at the SAME TEMPERATURE.
What is concentration?
500
True or False. Explain.
I can increase the concentration of my solution if I constantly add more solute to the liquid.
What is TRUE & FALSE?
I can increase the concentration by adding more solute until the solution is saturated. Then I can only increase the concentration if I heat the solution.

These are the things that happened in class when a chemical reaction took place.
What are gas formation, precipitate formation & temperature change?
