  • What is the basic functional unit of matter in chemistry?
    The atom is the basic functional unit of matter in chemistry.
  • How is matter defined in chemistry?
    Matter is anything that occupies space and has mass.
  • What are the three main types of matter?
    The three main types of matter are elements, compounds, and mixtures.
  • What is an element in terms of its atomic composition?
    An element is composed of only one kind of atom.
  • Give an example of an element and its chemical symbol.
    Carbon is an example of an element, and its symbol is C.
  • What distinguishes a compound from an element?
    A compound is made of two or more different elements chemically bonded together, while an element is made of only one kind of atom.
  • Is O2 considered an element or a compound, and why?
    O2 is considered an element because it is made up of only oxygen atoms.
  • What is a mixture in the context of matter classification?
    A mixture is matter composed of elements and/or compounds that are physically mixed together.
  • What is the key difference between a pure substance and a mixture?
    A pure substance has a single composition, while a mixture has a variable composition.
  • What question helps determine if a pure substance is an element or a compound?
    We ask if the substance can be separated into simpler substances; if not, it's an element, if yes, it's a compound.
  • What is a homogeneous mixture and give an example?
    A homogeneous mixture has a uniform composition throughout, such as air.
  • What is a heterogeneous mixture and provide an example?
    A heterogeneous mixture has a non-uniform composition, like oil and water.
  • What is the composition of water (H2O) in terms of elements?
    Water is composed of two hydrogen atoms and one oxygen atom.
  • How can you visually distinguish a heterogeneous mixture?
    You can see the different substances or phases in a heterogeneous mixture.
  • What is the first step in classifying a type of matter?
    The first step is to look at its composition to determine if it is a pure substance or a mixture.
