What is a metal?
100
In a chemical reaction, are you able to recover the original substances?
What is no? In a physical change , you can recover the substances. In a chemical change, a NEW substance is created.
100
Plastics, rubber, wood, and glass are all good _____________ because they help to prevent the flow of heat and electricity.
What is insulators?
100
A substance that tastes sour like an orange and changes a litmus paper red is...
What is an acid?
100
A salt is any compound made of a __________ and a ______________.
What is a metal and nonmetal?
200
A mixture of two or more metals and nonmetals.
What is an alloy?
200
True or False: Reactants are the new substances after the change in a chemical reaction.
What is false? (Products are the new substances, reactants are the substances BEFORE the change.
200
True or false: All metals are solid at room temperature and have good luster (shiny when polished).
What is false? (Most have good luster, but gallium and mercury are metals that are liquid at room temperature)
200
A substance like soap that tastes bitter and turns litmus paper blue is...
What is a base?
200
True or False: It's easy to melt salts because of their low melting points.
What is false? (They actually have extremely high melting points!)
300
If metals allow heat and electricity to flow easily, this means they are good ___________
What is conductors?
300
When iron combines with oxygen, it creates a new product better known as:
What is rust?
300
Metals are malleable, meaning they can be pounded with breaking.
What is true?
300
Combining five acid particles with five base particles would cancel each side out. What does this mean I did to them?
What is neutralize?
300
True or False: Salts are good conductors of heat and electricity.
What is true?
400
How easily a substance takes part in a chemical reaction
What is reactive?
400
Give two real-life examples of chemical reactions NOT already talked about in this game.
What is marshmellows roasting, iron rusting, milk souring, wood burning, cake baking, etc.?
400
Most metals are ductile, meaning they can be ____________
What is stretched into wire strands?
400
What number on the pH scale (a measure of the base/acid strength) is considered neutral?
What is 7?
400
Name two ways salts can be useful, based on what we discussed from the textbook.
What is seasoning food, preserving to keep from spoiling, and melting down icy roads?
500
Something that changes color in ways that let you identify the substance.
What is an indicator?
500
Give the appropriate descriptions for two signs of a chemical change.
What is forms a solid, forms a gas, temperature changes, releases light, color changes, forms tarnish?
500
Brass, bronze, and steel are all examples of useful metal materials called ____________
What is alloys?
500
If I had a high pH (12 charged particles), would I have a strong acid or base?
What is a base?
