Question

determine if the following are elements, molecules, compounds, heterogenous mixtures, or homogenous mixtures * 5 points
element molecule compound homogenous mixture heterogenous mixture
salt dissolved in water
soil
hydrogen gas (h2)
carbon (c)
sugar (c6h12o6)
this state of matter has an indefinite shape and indefinite volume * 1 point

Explanation:

Step1: Define concepts

An element is a pure - substance made of only one type of atom. A molecule is a group of two or more atoms held together by chemical bonds. A compound is a substance made up of two or more different types of elements chemically combined. A homogeneous mixture has a uniform composition throughout, and a heterogeneous mixture has a non - uniform composition.

Step2: Analyze salt dissolved in water

Salt (sodium chloride) dissolved in water forms a homogeneous mixture as the salt ions are evenly distributed in the water.

Step3: Analyze soil

Soil is a heterogeneous mixture as it contains different components like sand, clay, organic matter etc. which are not uniformly distributed.

Step4: Analyze hydrogen gas (H2)

Hydrogen gas (H2) is a molecule as it consists of two hydrogen atoms bonded together. It is also an element as it is made of only hydrogen atoms.

Step5: Analyze carbon (C)

Carbon (C) is an element as it is made of only carbon atoms.

Step6: Analyze sugar (C6H12O6)

Sugar (C6H12O6) is a compound as it is made up of carbon, hydrogen, and oxygen atoms chemically combined.

Answer:

Salt dissolved in water: Homogenous Mixture
Soil: Heterogenous Mixture
Hydrogen Gas (H2): Molecule, Element
Carbon (C): Element
Sugar (C6H12O6): Compound
