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.
What is the effect of NaCl and CaCl2 on the boiling point of water

The water with solved ions has greater boiling point. The dissolved salts increase the boiling point of water.

Why are alloys useful

Alloys are useful (if this is what the question is getting at) because mixing elements of the periodic table alters their colligative properties.

i.e. mixing two metals could change substance's melting point, allowing it to more easily resist high temperatures. Also, mixing metals can change the way they bind together, and create an altogether stronger material than you can find using any single metal alone.They can improve a metal's properties

What forces hold ionic solids together

Ionic bonds

What would dissolve the best in water

vinegar

HCI ~APEX

Which intermolecular force would affect melting point the most

Hydrogen bonding

Which intermolecular force would cause the highest boiling point

Hydrogen Bonding

What is the vapor density of light diesel oil

apex

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.

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

Dirt is a heterogeneous mixture.

Which ionic compound will lower the freezing point the most of 1 mol of it is added to 1 mol of it is added to 1 L of water

NaCl

What is the following of a base

A base contain the hydroxyl group (OH)-.

What is a homogeneous mixture equivalent to

A homogeneous mixture has only one phase.

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.

Which of the following is a Solution

Apex- Brewed Coffee

Which of the following is an electrolyte solution

The answer is "Ions in water" on Apex
