Identify the forces that hold atoms and molecules together at the atomic level Give an example of how these forces are involved in a chemical reaction?
Atoms and molecules are held together at the atomic level by the electromagnetic interactions between electrons, protons, and ions. For example, an ionic compound is held together by the attraction between the positive and negative charges of its constituent ions. Two atoms forming a covalent bond are held together by the mutual attraction they have toward one or more electrons. This interaction is quantized through the concepts of electronegativity and charge.
What else can I help you with?
How can you determine if a chemical reaction is occurring, and what are two methods to identify this process?
You can determine if a chemical reaction is occurring by observing changes in the physical or chemical properties of the substances involved. Two methods to identify this process are observing the formation of a precipitate or a color change in the reaction mixture.
What is the stereospecific definition of a chemical reaction?
A stereospecific chemical reaction is one where the relative spatial arrangement of atoms in the reactant molecules determines the spatial arrangement of atoms in the products. This means that the reaction follows a specific pathway based on the stereochemistry of the molecules involved.
What is an atom or molecule called when involved in a chemical reaction?
Before the reaction, the atoms and molecules are called reagents. After the reaction, the resulting atoms and molecules are called products.As a reaction occurs, the reagents may form an activated complex and almost immediately decay into products.
Look at the chemical equation above. The subscript 4 in the reactants indicates that?
There are 4 molecules of that particular reactant involved in the reaction.
How can one determine the molecularity of elementary reactions?
The molecularity of an elementary reaction can be determined by looking at the number of reactant molecules involved in the reaction. If only one reactant molecule is involved, the reaction is considered unimolecular. If two reactant molecules are involved, the reaction is bimolecular. And if three reactant molecules are involved, the reaction is termolecular.
Reaction that break apart large molecules are involved in which type of digestion?
chemical
Is the number before a chemical formula indicates how many molecules are involved in a chemical reaction?
Yes, that is true.
What general terms does a chemical equation indicate?
Chemical formulas of reactants and products; number of molecules involved in the reaction.

What are the two coefficients?
In a chemical equation, coefficients represent the no. of molecules or atoms involved in a complete chem. reaction.
What is the name of a number in front of a chemical formula in an equation called?
This is the number of molecules or atoms involved in the reaction.
What is an atom or molecule called when involved in a chemical reaction?
Before the reaction, the atoms and molecules are called reagents. After the reaction, the resulting atoms and molecules are called products.As a reaction occurs, the reagents may form an activated complex and almost immediately decay into products.
How is heat involved in chemical changes?
Heat increases the speed at which the molecules move, thus increasing the speed of the reaction.
How do you identiy each chemical reaction?
You can identify each chemical reaction by naming it,
Molecules involved in a chemical reaction must collide to react What is this concept called?
This concept is called collision theory. It states that in order for a chemical reaction to occur, reactant molecules must collide with enough energy and proper orientation.
Look at the chemical equation above. The subscript 4 in the reactants indicates that?
There are 4 molecules of that particular reactant involved in the reaction.
