  • Which of the following best describes an element?
    A mixture of different chemical components
    A substance that can be broken down easily
    A compound with multiple properties
    A pure substance made of atoms of the same kind
  •  15
  • An XRF spectrometer is primarily used to:
    Measure temperature
    Identify elements in rocks and soil
    Measure electrical conductivity
    Detect radioactivity
  •  15
  • What happens when magnesium burns in oxygen?
    The oxygen is destroyed
    Nothing changes
    The magnesium disappears
    It creates a new compound with different properties
  •  15
  • A compound differs from an element because:
    It has no mass
    It exists only in laboratories
    It cannot be seen
    It is formed by chemically combining different elements
  •  15
  • In the word equation "Iron + Sulfur → Iron sulfide", what are the reactants?
    Magnesium
    Oxygen
    Iron and sulfur
    Iron sulfide
  •  15
  • An IR spectrometer helps scientists by:
    Detecting light waves
    Measuring temperature
    Analyzing chemical bond vibrations
    Predicting weather patterns

  • Which statement about elements is TRUE?
    Elements are the simplest form of matter
    Elements are complex mixtures
    Elements always exist as liquids
    Elements can be easily broken down
  •  15
  • When scientists use an XRF spectrometer on a rock, they are primarily trying to:
    Determine its color
    Measure its weight
    Calculate its age
    Identify which elements are present
  •  15
  • A chemical reaction involves:
    Freezing of chemical bonds
    No change in atomic structure
    Complete destruction of matter
    Rearrangement of atoms
  •  15

  •  15
  • The term "reactants" in a chemical equation refers to:
    The chemical tools
    The laboratory equipment
    The starting materials
    The final products
  •  15
  • What makes a compound different from its original elements?
    It has identical properties
    It has new, unique properties
    It cannot be separated
    It weighs less
  •  15
  • Scientists use IR spectrometers to:
    Measure sound waves
    Weigh substances
    Detect chemical "signatures"
    Predict chemical reactions
  •  15
  • When iron and sulfur combine, they form:
    An element
    A gas
    Iron sulfide
    A mixture
  •  15
  • An element cannot be:
    Measured
    Broken down by ordinary means
    Heated
    Seen under a microscope
  •  15
