Structure of Matter
The smallest unit of an element that still has the properties of that element.
What is an atom?
The type of change occurs when one or more new substances are formed.
What is a chemical change?
Color can be considered this type of property .
What is a physical property?
Materials made by humans through chemical processes, often using natural resources.
What are synthetic materials?
The name of Ms. Smith' dog.
Who is ReeseyMoney300?
The subatomic particle that has a positive charge
What is a proton?
A substance produces bubbles when mixed with another substance. What could the bubbles indicate?
The formation of a gas, which can be evidence of a chemical reaction.
Flammability can be considered this type of property.
What is a chemical property?
Plastic can be considered what material.
What is a synthetic material?
Ms. Smith worked at this school before coming to Warrendale.
What is ORA ?
The subatomic particle has a negative charge.
What is an electron?
Two signs that may indicate a chemical reaction.
color change, temperature change, gas formation, precipitate formation, light, or odor change.
The mass, volume, and density of a block of metal can be considered as this type of property.
What are physical properties?
Name one synthetic material that is commonly used in everyday life.
Possible answers: plastic, nylon, polyester, rubber, or synthetic fibers.
The name of Ms. Smith's son.
Who is Cam'ron?
Protons and Neutrons are located here inside of an atom.
What is the nucleus?
A student mixes two clear liquids. The mixture suddenly becomes cloudy and a solid forms at the bottom. What evidence suggests a chemical reaction occurred?
A new solid/precipitate formed, indicating a new substance may have been produced.
A material's ability to react with oxygen and form a new substance is an example of this type of property.
What is a chemical property?
Why are synthetic materials useful in products such as clothing, containers, and building materials?
They can be designed to have specific useful properties, such as strength, flexibility, durability, or resistance to water.
Ms. Smith was this age when she finished High School.
What is 16 years old?
An atom has 6 protons, 6 neutrons, and 6 electrons. How many protons does it have, and what does that number tell you?
It has 6 protons, which identifies the element as carbon.
During a reaction, the temperature increases even though the substances were not heated. What does this evidence suggest?
The reaction released energy as heat, providing evidence that a chemical reaction occurred.
Explain the difference between a physical property and a chemical property.
A physical property can be observed or measured without changing the substance into a new substance. A chemical property describes how a substance can react to form new substances.
Scientists develop a new material that is lightweight, strong, flexible, and resistant to water. Why might this material be useful for making products?
Its specific properties make it useful for products that need to be lightweight, strong, flexible, and water-resistant.
Ms. Smith hates this subject.
