A pure substance is defined as a material that has a consistent composition and distinct properties throughout. Among the options listed, a compound is classified as a pure substance because it consists of two or more elements chemically bonded together in a fixed ratio, exhibiting uniform characteristics. In contrast, solutions, colloids, and homogeneous mixtures are not pure substances, as they can contain different components that may not have a fixed composition.
CO2(aq) because a solution means the substance is dissolved in water.
This is a homogeneous solution.
A mixture, specifically a homogeneous mixture called a solution.
No, a homogeneous mixture is a solution where components are evenly distributed at the molecular level. When a substance dissolves in a solution, it forms a homogeneous mixture with the solvent.
A blue liquid can be classified as a heterogeneous mixture, a solution, or a pure substance depending on its composition. If the blue color comes from a uniform distribution of a dye in a solvent, it is likely a homogeneous solution. If the blue color results from suspended particles or separate phases, it would be a heterogeneous mixture. If the liquid is a single chemical compound that is blue in color, then it would be considered a pure substance.
A solution of dissolved sugar in water would be classified as a homogeneous mixture, also known as a homogeneous solution. This means that the sugar molecules are evenly distributed throughout the water, resulting in a uniform composition.
a pure substance. either a compound or an element. Also, a solution, which is a homogeneous mixture, not a pure substance.
Pure sugar is a compound, which is a pure substance. If you dissolve sugar in water, you will have a homogeneous mixture, which is a solution.
CO2(aq) because a solution means the substance is dissolved in water.
This is a homogeneous solution.
Sugar water solution is homogeneous but not a compound.
No,bromine is not heterogenous.It is a pure element.
This is a homogeneous solution.
A substance is matter that is uniform in composition. A substance can be an element or compound. A solution is another name for a homogeneous mixture. It is also uniform in composition, but a solution is made by physically combining two or more substances.
Sugar water solution is homogeneous but not a compound.
A compound is a substance formed by the chemical combination of two or more elements in fixed proportions. A solution is a homogeneous mixture of two or more substances where one substance (solute) is dissolved in another substance (solvent).
No, a salt solution is not a pure substance. It is a mixture of salt (solute) dissolved in water (solvent). A pure substance contains only one type of element or compound with a fixed chemical composition.
