A mixture of water and undissolved substances is a heterogeneous mixture because it is comprised of different substances. A heterogeneous mixture with undissolved substances that eventually settle is called a suspension. If the substances are too small to settle it's called a colloid.
What else can I help you with?
Which of the following is not a mixture a. pure water b. seawater c. air d. brass?
Answer a. Pure Water is not a mixture - it is a compound. Seawater is a mixture of water and salts, air is a mixture of gases and brass is a mixture (an alloy) of copper and zinc metals.
Is river water a homogeneous or heterogeneous mixture?
River water is generally a heterogeneous mixture based on the different components it is carrying. Water by definition is not an element, rather a molecule comprised of them.
A mixture of flour and water is called a mixture because the substances do not dissolve?
heterogeneous mixture
Is salt water pure substance or homogeneous mixture or a heterogeneous mixture?
Homogeneous mixture
A mixture in which pure substances are unevenly distributed throughout the mixture?
A type of mixture in which different materials are spread out unevenly is known as a heterogeneous mixture. It is a combination of substances with no uniform composition or properties.
What is mixture of water and nondissolved substance?
A mixture of water and a non-dissolved material is a suspension. Examples of suspensions include muddy water, sand in water, chalk in water, oil and water, and other mixtures such as this.
Is concrete a compound after the water evaporates and it hardens?
Concrete is not a compound after water evaporates and it hardens. Concrete is a mixture of aggregate materials (such as sand and gravel) and cement, which binds the materials together. When water is added to the mixture, a chemical reaction occurs with the cement that causes it to harden and bind the aggregate materials together.
What is a mixture of materials dissolved in stream water?
A mixture of materials dissolved in stream water is called a solution. This occurs when substances like salts, minerals, and organic matter dissolve in water and become distributed evenly throughout the water.
Between heterogeneous mixtures solutions compounds or elements how would you classify the following materials - air milk and water?
air = solution milk = heterogeneous mixture water= compound
Is rainwater a heterogeneous or a homogeneous?
If the rain water contain powdered materials the mixture is nonhomogeneous.
Is river water element or compound or mixture?
Muddy river water is a mixture of different materials. The moving river keeps it muddy. If the water stops moving, the muddy material will precipitate and settle to the bottom.
Is muddy water a mixture a compound or an element?
Muddy river water is a mixture of different materials. The moving river keeps it muddy. If the water stops moving, the muddy material will precipitate and settle to the bottom.
Is river water an element mixture or a compound?
Muddy river water is a mixture of different materials. The moving river keeps it muddy. If the water stops moving, the muddy material will precipitate and settle to the bottom.
Is a river water mixture or compound or element?
Muddy river water is a mixture of different materials. The moving river keeps it muddy. If the water stops moving, the muddy material will precipitate and settle to the bottom.
What is the difference of a solution and a suspension?
Suspension-Mixtures of water and nondissolved material. Solutions-All of the components are evenly distributed throughout the solution like its breaks apart and disperses
What Mixture is made up of different materials that can be easily be separated?
Heterogeneous mixtures are mixtures that can easily be separated. For instance, sand mixed with water is a heterogeneous mixture that can be separated by filtration. Another example of a heterogeneous mixture is salt mixed with pebbles, which can be separated by adding water to the mixture.
What is a heterogeneous solid?
This is a mixture of materials which can be distinguished from each other.
