Conductivity refers to the ability of a substance to conduct electric current, which provides insights into its ionic or molecular nature. Substances that conduct electricity well, such as salts and acids, typically dissociate into ions in solution, indicating they are electrolytes. Conversely, poor conductors, like most nonmetals, often exist as neutral molecules and do not produce free ions. Thus, conductivity helps classify substances as ionic or covalent and indicates their potential behavior in chemical reactions.

What are three things that chemical equations can tell you about a chemical reaction?
A chemical equation tells you what substances are reacting, what substances are produced and, in a balanced equation, provides the coefficients to tell us in what ratio the substances react or are produced.
What does a word equation or a chemical reaction tell you?
I think that a chemical equation tells a chemist that substances you start with and substances you end with
How can a chemical change help you tell the difference between a compound and an element?
A chemical change can help you tell the difference between an element and a compound because an element is a pure substance that cannot be broken down or separated into other pure substances through chemical change while a substance that is made from two or more elements that have combined in a chemical change are known as compounds.
How you can tell if a mixture is a chemical reaction?
a mixture is by definition not a chemical reactionA mixture is two or more substances which have been combined such that each substance retains its own chemical identity.So a mixture cannot be a chemical reaction, signs of a chemical reaction include:colour changeprecipitation (formation of a solid)effervescence (giving off gas)And every single chemical reaction involves gives of some heat.
How can you tell if a chemical change has occured when you mix two substances?
i think it would be that it would be like chemicals like mixing atoms together.
What does conductivity tell us about the nature of chemical substances?
Conductivity indicates how well a substance can conduct electricity. Certain substances, like metals, are good conductors due to freely moving electrons, while others, like nonmetals, are poor conductors. The presence or absence of conductivity can provide information about the type of bonding present in the substance (metallic, ionic, or covalent).
What are three things that chemical equations can tell you about a chemical reaction?
A chemical equation tells you what substances are reacting, what substances are produced and, in a balanced equation, provides the coefficients to tell us in what ratio the substances react or are produced.
How can you tell by look at a chemical equation which substances are products?
In a chemical equation, the substances on the right side of the arrow are the products. These are the new substances that form as a result of the chemical reaction taking place.
How can you tell chemical change?
The consequence of a chemical change is the modification of the molecular nature.
What does a word equation or a chemical reaction tell you?
I think that a chemical equation tells a chemist that substances you start with and substances you end with
Chemical properties tell you how something?
Chemical properties describe how a substance behaves in a chemical reaction, such as its reactivity, ability to react with other substances, and changes in composition. These properties are determined by the substance's chemical composition and structure.
How you tell substances apart?
HOW DO WE DISTINGUISH SUBSTANCES? HOW DO WE DISTINGUISH SUBSTANCES?
Which is chemical equation?
A chemical Equation is a shorthand form of a chemical reaction. chemists use it to help them tell the substances that are present such as reactants, products, or proportions.Some equations also tell the physical state of a substance.
Is it possible to tell whether a chemical change has occurred by watching atoms form new substances?
if the atoms form substances that are chemically different from the reactants, then a "chemical" change has occurred.
How can a chemical change help you tell the difference between a compound and an element?
A chemical change can help you tell the difference between an element and a compound because an element is a pure substance that cannot be broken down or separated into other pure substances through chemical change while a substance that is made from two or more elements that have combined in a chemical change are known as compounds.
Does a chemical formula describes a chemical reaction?
Yes, chemical equations describe chemical reactions. A chemical equation tells you what substances are reacting, what substances are produced and, in a balanced equation, provides the coefficients to tell us in what ratio the substances react or are produced.
How do you tell substances apart?
Substances can be identified based on their physical and chemical properties, such as color, solubility, melting and boiling points, odor, and reaction to certain chemicals. Techniques like spectroscopy, chromatography, and mass spectrometry can also be used to analyze substances and determine their unique characteristics.
