  • Is carbon dioxide an element, compound, or mixture?
    Carbon dioxide is a compound.
  • Is titanium an element, compound, or mixture?
    Titanium is an element.
  • Is carbon dioxide a pure substance or mixture?
    Carbon dioxide is a pure substance.
  • Salad dressing: homogeneous, heterogeneous, solution, colloid, suspension?
    Salad dressing is a heterogeneous mixture.
  • Is copper a substance or mixture?
    Copper is a pure substance (element).
  • Matter with a composition that is always the same
    Pure substance.
  • Is a dog an element, compound, or mixture?
    A dog is a mixture.
  • Water is an example of
    A compound.
  • Brass is a combination of a number of elements. Its exact composition can vary. Mixture or compound?
    Brass is a mixture (alloy).
  • Is chocolate chip ice cream homogeneous or heterogeneous?
    Chocolate chip ice cream is heterogeneous.
  • Is mouthwash an element, a compound, a homogeneous mixture, or a heterogeneous mixture?
    Mouthwash is a homogeneous mixture.
  • Classify each of these reactions.
    Reactions are chemical changes involving matter.
  • Classify each substance as an element or a compound.
    Elements have one type of atom; compounds have two or more different elements.
  • Classify each compound as ionic or molecular.
    Ionic compounds are made of ions; molecular compounds are made of molecules.
  • A crystal of NaCl is
    A compound (ionic).
  • Classify each of the following substances as an element, a compound, or a mixture.
    Elements: gold; compounds: water; mixtures: air.
  • Beach sand: homogeneous or heterogeneous?
    Beach sand is heterogeneous.
  • Is muddy water classified as a solution, a colloid, or a suspension?
    Muddy water is classified as a suspension because it is a heterogeneous mixture where solid particles are dispersed in water and can settle out over time.
  • Is coffee considered a mixture or a solution?
    Coffee is considered a mixture because it contains various substances physically combined. If it appears uniform throughout, it is specifically a homogeneous mixture, also known as a solution.
  • How is an emulsion different from a solution in terms of the classification of matter?
    An emulsion is a type of heterogeneous mixture where two immiscible liquids are mixed together, resulting in distinct phases, while a solution is a homogeneous mixture with a uniform composition throughout.
  • Is a heterogeneous mixture the same as a solution?
    No, a heterogeneous mixture is not the same as a solution. A heterogeneous mixture has visibly distinct components and is not uniform throughout, while a solution is a homogeneous mixture with a uniform composition.
