how are all chemical reaction alike?

A chemical reaction rearranges the constituent atoms of the reactants to create different substances as products. The properties of the products are different from those of the reactants. ... If a physical change occurs, the physical properties of a substance will change, but its chemical identity will remain the same.

Summary. A chemical property describes the ability of a substance to undergo a specific chemical change. A chemical reaction is a process that occurs when one or more substances are changed into one or more new substances.

A chemical reaction happens when one or more chemicals are changed into one or more other chemicals. Examples: iron and oxygen combining to make rust. vinegar and baking soda combining to make sodium acetate, carbon dioxide and water.

In a chemical reaction, the atoms and molecules that interact with each other are called reactants. ... No new atoms are created, and no atoms are destroyed. In a chemical reaction, reactants contact each other, bonds between atoms in the reactants are broken, and atoms rearrange and form new bonds to make the products.

(1) It must represent a true chemical changes. (2) All the reactants and the products of the chemical reaction must be in the form of their respective chemical formulae / symbols. (3) The total number of atoms of all the elements must be same in both sides. (4)It must be molecular.

There is no difference. Chemical changes are also known as Chemical Reactions - a change that results in the formation of new chemical substances. ... Chemical reaction is a process of changing from one chemical state to another and chemical change is a change in the state of a material.

These reactions always occur in pair. That is, an oxidation is always coupled to a reduction. When something gets oxidized, another agent gains those electrons, acting as the oxidizing agent, and gets reduced in the process.

Yes, every chemical reaction can theoretically be in equilibrium. ... The only thing that stops chemical reactions from being "in equilibrium" is the lack of the proper number of molecules. For a reaction to be in equilibrium, the concentrations of reactants and products must be related by the equilibrium constant.

The elements in each group have similar chemical properties. The elements in each group have identical physical properties. The atomic number of each element increase by 7 down through the group. Each member of the group has the same number of electrons in the outer shell.

Atoms are indivisible and indestructible. All atoms of a given element are identical in mass and properties. ... A chemical reaction is a rearrangement of atoms.

A chemical change must occur. Chemical bonds are made or broken in order to create a new molecule. One example of a chemical reaction is the rusting of a steel garbage can. That rusting happens because the iron (Fe) in the metal combines with oxygen (O2) in the atmosphere.

['They have same functional group.', 'they have same general formula of representation.', 'they have same general method of preparation.', 'They have same chemical properties.', 'Adjacent members are differ from each other by CH2 unit.']

Atoms are rearranged in a chemical reaction. The substances that: react together are called the reactants. are formed in the reaction are called the products.

All atoms of a given element are identical in size, mass and chemical properties. Atoms are indivisible particles which can neither be created nor destroyed in a chemical reaction. In a chemical reaction, atoms only get rearranged. An atom of an element does not change into the atom of another element.

Law of conservation of mass. No atoms are created or destroyed in a chemical reaction. Instead, they just join together in a different way than they were before the reaction, and form products . This means that the total mass of the products in a chemical reaction will be the same as the total mass of the reactants .

All atoms of the same element have the same number of protons, but some may have different numbers of neutrons. ... Different isotopes of an element generally have the same physical and chemical properties. That's because they have the same numbers of protons and electrons.

Atoms are not CREATED or DESTROYED during a chemical reaction. Scientists know that there must be the SAME number of atoms on each SIDE of the EQUATION. To balance the chemical equation, you must add COEFFICIENTS in front of the chemical formulas in the equation.
