Is decomposing water by passing an electric current through it a chemical or physical change?
Decomposing water by passing an electric current through it is a chemical change because it involves the breaking of the chemical bonds in water molecules (H2O) to form hydrogen gas (H2) and oxygen gas (O2). This reaction results in the formation of new substances with different chemical properties.

What does it take to break chemical bonds?
Chemical bonds can be broken by providing energy in the form of heat, electricity, or light. This extra energy helps overcome the attraction between atoms in the bond, causing them to separate. Different types of bonds require different amounts of energy to break.
What happens to chemical bonds during energy exchanges?
During energy exchanges, chemical bonds can break or form. When bonds break, energy is absorbed, while when bonds form, energy is released. This process is essential for chemical reactions to occur and for energy transfer in biological systems.
What can break chemical bonds of atoms?
A chemical reaction can break the chemical bonds that hold atoms together. A change in temperature can also do it, as can an electric current.

When an electric current passes through water takes place breaking down the compound into hydrogen and oxygen. a physical change an atomic change a chemical change an elemental change?
When an electric current passes through water, it breaks down the compound into hydrogen and oxygen, which is known as electrolysis. This process involves the breaking of chemical bonds and the formation of new substances, indicating a chemical change. Thus, the correct answer is a chemical change.
Contrast the forming and breaking of chemical bonds in terms of energy changes?
The formation of chemical bonds releases energy. It is an exothermic process. The breaking of chemical bonds takes energy. It is an endothermic process.

How do you convert electrical energy into chemical energy?
Electrical energy can be converted into chemical energy through a process called electrolysis, which involves passing an electric current through a substance (such as water) to break down its molecular components and store the energy in chemical bonds. This process can produce hydrogen gas or other chemical compounds that store the electrical energy for later use in fuel cells or other applications.
What is chemical rection?
A chemical reaction is a process where one or more substances (reactants) are transformed into different substances (products) by breaking and forming chemical bonds. This process involves the rearrangement of atoms and the breaking or forming of chemical bonds.
What causes water particles to split into hydrogen and oxygen?
Water particles split into hydrogen and oxygen through a process called electrolysis, which involves passing an electric current through water. This current breaks the chemical bonds holding the water molecules together, resulting in the release of hydrogen gas at the cathode and oxygen gas at the anode.
What happens to chemical bonds when new compounds are formed in a chemical reaction?
In a chemical reaction, existing chemical bonds are broken and new bonds are formed between atoms to create new compounds. This process involves the exchange, sharing, or transfer of electrons between atoms to achieve stability in the newly formed molecules.
The process of atoms and new bonds joing together?
