What is a heterogeneous mixture

Heterogeneous means of different types. So a heterogeneous mixture is a mixture of dissimilar items. Homogeneous means of the same type so a homogeneous mixture would be a mixture of similar items.

A mixture where two or more substances are mixed together but are not chemically combined is called as an heterogeneous mixture.

In chemistry, heterogeneous mixture is a mixture of two or more different substances in the form of solution or colloids. For example, salad is an heterogeneous mixture


A heterogenous mixture is not uniform in composition and properties throughout.
Does sugar affect the boiling point of water

Adding sugar to boiling water it will increase the boiling temperature very slightly

What causes the pressure inside oxygen tanks to change as they are filled

The number of gas molecules changes.
the number of gas molecules changes

How is the combined gas law modified to form the ideal gas law

Each side of the equation is divided by the number of moles

What does a dissolved salt look like

The ions in the salt are surrounded by water molecules.

What is the best way to make a supersaturated solution

Heat the solution

Which intermolecular force would affect melting point the most

Hydrogen bonding

What forms of the ideal gas law would you use to calculate the number of moles of gas

Probable you think to the law of Avogadro.

What would mix the best with water non polar molecules polar molecules fatty molecules symmetrical molecules

Polar molecules are mixed better with water.

Which of the following is an example of a heterogeneous mixture water saltwater dirt or brass

Dirt is a heterogeneous mixture.

What is the molality solution that has 3 mol of glucose in 6 kg if water

This molality is 90,08 g/kg.

What will result from increasing the temperature of gas

Increasing the temperature of gas the volume increase.

Why can liquid boil at low temperatures

It is possible if the pressure is also low.

What is the molality of a solution that has 4 mol of KCl in 0.800 kg of water A.

The molality is 5.

What is a solvent

A solvent is a liquid that dissolves a solute. The solvent is the component of a solution that is present in greater amount. Perhaps the most common solvent in everyday life is water. Many other solvents are organic compounds, such as benzene, tetrachloroethylene, or turpentine.
