Please classify these as either elements, compounds, solutions, or heterogeneous mixtures, please specify it it's a colloid or a suspension.
Copper, copper chloride(CuCl2), chex mix, fog, water, copper chloride(CuCl(aq), iron, sodium chloride, sand, vinegar, NaHCO3(what's the name for this?), vinegar, glue, koolaid, and sulfur. Thank you SO much for you help; it really means a lot.
Classifications of the material listed in the question is indicated below against each substance.
Copper chloride(CuCl2): Compound
Chex mix: I am not cleat what substance is this. However, the term mix indicates that it is some kind of mixture
Fog: Suspension, which is a type of mixture.
Copper chloride (CuCl, aq): Solution. The suffix 'aq' indicates that it is a solution in water.
Iron: Element. However please note that the word iron is also used for loosely for some alloys of iron. Such alloys form homogeneous mixtures.
Sodium chloride: Compound
Sand: Heterogeneous mixtures
NaHCO3(Sodium Bicarbonate): Compound,
Glue: Glues can be of many different types. None of these are elements. All the glues used of sticking things together that have some liquids that must evaporate for the things to remain stuck, are mixtures.
Koolaid: This appears to be brand name of some product. I am not aware of this product.
