Matter
100
A building block of matter.
What is an element?
100
This is one way to describe a substance and it sounds very scientific (listed on the blue vials)
What is chemical name?
100
This process of mixing a solid into a liquid until it disappears.
What is dissolving? (NOT a chemical reaction because nothing new is formed.)
100
Evidence of a chemical reaction seen when we added water to the mystery mixture.
What is a gas being produced? (not bubbling or fizzing--that is EVIDENCE of a gas being produced)
100
Co represents this many elements.
What is one (cobalt)?
200
A simple substance that cannot be broken down.
What is an element?
200
This is one of the ways to describe a substance and it is what we tend to use in every day language (it was on the vials in parenthesis).
What is common name?
200
This process of changing gas to a liquid.
What is condensation? (NOT a chemical reaction because no new substance is formed)
200
A sign of a chemical reaction which was observed during the large scale reactions
What is temperature change?
200
CO represents how many elements?
What is two (carbon and oxygen).
300
The symbol "Cl" is for this element.
What is Chlorine, not Carbon and Iodine?
300
This is a way to describe a substance which is like a recipe with ingredients and quantities.
What is a chemical formula?
300
Evidence of a chemical reaction which often results in bubbling or fizzing.
When a gas is being produced?
300
Evidence of a chemical reaction that was seen after evaporation.
What is color change?
300
The phase where matter takes the shape of its container.
What is liquid.
400
If you see the formula NaK, there are this many different elements.
What is 2? (sodium and potassium. The small case letter always goes with the large letter)
400
In the formula, MgSO4, there are this many "pieces" of sulfur.
What is one. (if there is no subscript after the symbol, it is always one)
400
Evidence of a chemical reaction that makes a loud noise and sometimes results in fire.
What is an explosion?
400
Process where a liquid changes to a gas.
What is evaporation? (not a chemical reaction because no new product is formed)
400
The phase where matter will spread out to take up all available space.
What is gas.
500
The one or two letters that stand for the name of an element.
What is an element symbol?
500
The chemical name for this substance is dihydrogen oxide.
What is water?
500
In a chemical reaction, beginning substances change and this is what is left afterwards.
What is something new?
500
Chemical that showed evidence of a chemical reaction with a color change in the evaporation tray.
What is ascorbic acid or vitamin C? (turned orange when it reacted with oxygen in the air)
500
The phase where matter keeps its shape.
What is solid.
