All of the elements of the Periodic Table cannot be broken down into simpler substances.
What else can I help you with?
Which substance can be broken down by a chemical change The answer is Hexane--but why?
Hexane is a compound. All chemical compounds can be broken down by chemical change (chemical reactions of many types) - not only hexane. All the other choices are elements which cannot be broken down by chemical changes.
What is evidence that a chemical change has happened?
Evidence of a chemical change includes a change in color, formation of a precipitate, evolution of gas bubbles, or a change in temperature. Additionally, if the substance cannot be easily reversed back to its original form, it is likely a chemical change has occurred.
What type of change occurs when a new substance is formed that has different properties from the original substance?
A chemical change occurs when a new substance is formed with different properties from the original substance. This change involves the rearrangement of atoms and the formation of new chemical bonds. It is typically irreversible.
Which two substances cannot be broken down by chemical change?
Two substances that cannot be broken down by chemical change are elements and compounds. Elements are fundamental building blocks of matter that cannot be broken down into simpler substances by chemical reactions. Compounds are made up of two or more different elements chemically bonded together in fixed ratios, and they also cannot be broken down into simpler substances by chemical reactions.
What takes place during a chemical change?
During a chemical change, the identity and composition of a substance are altered as new chemical bonds are formed or broken. This change is usually irreversible and produces a new substance with different chemical properties compared to the original materials. Examples include combustion, oxidation, and digestion.
Substance A can not be broken down by a chemical change Substance Z can What can be concluded?
Substance A is likely an element, as it cannot be broken down by a chemical change. Substance Z is likely a compound, as it can be broken down by a chemical change into simpler substances. From this information, it can be concluded that substances A and Z have different chemical compositions and properties.
What happens when a clear substnace undergoes a chemical change?
It is no longer that same substance. A chemical changes the identity of the substance. Individual atoms cannot be broken down into smaller parts by normal physical or chemical change.
Which substance can be broken down by a chemical change The answer is Hexane--but why?
Hexane is a compound. All chemical compounds can be broken down by chemical change (chemical reactions of many types) - not only hexane. All the other choices are elements which cannot be broken down by chemical changes.
Are broken pieces a chemical change?
No, it is a physical change as the identity of the substance remains the same. Broken glass is still glass.
What substance can only be broken down by chemical change?
A substance that can only be broken down by chemical change is a compound. Compounds are made up of different elements chemically bonded together, and breaking these bonds requires a chemical reaction. Physical changes, such as melting or dissolving, cannot break compounds down into their individual elements.
What is substance can be separated into simpler substance is only by chemical means?
The substance is a compound, which forms chemical bonds that cannot be physically separated, but only by a chemical change.
What any substance cannot be broken down into simpler substances?
This change is possible.
Is a broken glass a chemical change?
Physical change because the molecules have not changed to form a new substance.
What substance cannot undergo a chemical change?
If you are not concerned about atoms, electrons, neutrons, protons and other sub atomic particles, but confine to chemical substances occurring in nature or man made, the substance that cannot be broken into simpler substances is an "element" (usually enumerated in a periodic table).A chemical element cannot be decomposed into a simpler substance.Elements. They are defined as substances in their simplest form and cannot be broken down or decomposed into any simpler substances. They include all elements in the periodic table of elements.
What is involved in every chemical change?
One substance changing into a completley different substance. It cannot be reversed.
What does a substance mean?
A pure substance is a substance that cannot be separated by means of physical separation but only by chemical. It is a change in time.
Why physical change can easily be reversed but chemical change cannot?
Physical changes are generally easy to reverse because NO ENERGY is produced by the substance.A Chemical change cannot be reversed because ENERGY is produced by the substance forming a new substance.
