Alchemists & History
This group of people from the Middle Ages were interested in materials and potions and thought they could turn steel into gold.
Alchemists
Describe the difference between and Chemical Reaction and a Physical Reaction
Physical: change in appearance only
Chemical: a new substance is formed, typically not reversible
This state of matter flows and takes the shape of its container.
Liquid
Vinegar is an example of this type of sour-tasting liquid.
Acid
Pennies have a thin coating of this metal.
Copper
In the Middle Ages, alchemists were famous for making these "magical" mixtures
Potions
True or False: Mixing baking soda and water creates a chemical reaction.
False
Matter is made of these.
Atoms
This type of weather is created when rain and carbon dioxide mix together.
Acid Rain
This process involves air reacting with copper to turn it a blue-green color over time.
Oxidation
The word "gas" originates from this word
Chaos
This specific mixture of two household items creates a chemical reaction resulting in a new substance called "GOO".
Borax and Glue
True or False: A new substance is formed when a physical reaction happens.
False
Besides water, this other chemical creates Acid Rain
Carbon Dioxide, pollution
When you place this type of metal nail into a bag of pennies, salt, and vinegar, the nail turns a copper color.
Steel
Alchemists were specifically known for trying to turn this common metal into gold.
Steel
In an experiment where baking soda and vinegar are mixed in a sealed bag, the bag expands or may even explode because of this specific movement of gas particles.
The particles expand the bag because they multiply and fill it.
According to the law of conservation of matter, if you freeze a 230-gram cup of lemonade into a popsicle, its total weight will be this.
230grams
Acid rain is a serious environmental issue because it has the power to slowly do this to stone and rock.
Dissolve them
When cleaning pennies in a salt and vinegar solution, the weight of the pennies actually decreases because the copper layer is being moved to this.
The salt and vinegar solution
This country's "ch" sounds like a "g"
Holland
To identify which of three white powders is baking soda, you must find the one that bubbles when mixed with vinegar but does NOT bubble when mixed with this liquid.
Water
This scientific term describes the process of materials falling apart, decomposing, or rotting over time.
Decay
Besides vinegar, this substance is often used in chemical reaction experiments to create "Elephant Toothpaste" or foam slime.
Hydrogen Peroxide
This is the substance created when cleaning off a penny's oxidation
Copper Nitrate
