Answer
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
