Which substance cannot be broken down by a chemical change?
All of the elements of the Periodic Table cannot be broken down into simpler substances.
Can metal elements be broken down by physical or chemical methods?
Elements are substances that cannot be broken down into any simpler substances. Hence they cannot be broken down by chemical methods. They may change in appearance if physical methods, but chemically, they still remain as the element.
Can sodium be decomposed by a chemical change?
No. Sodium is an element and elements cannot be broken down (decomposed) by a chemical change.
Substance that cannot be changed into simpler substances by chemical means?
Elements cannot be changed into simpler substances by chemical means. To change them into simpler particles, you need nuclear means.
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.
Which substance cannot be broken down by a chemical change?
All of the elements of the Periodic Table cannot be broken down into simpler substances.
Can metal elements be broken down by physical or chemical methods?
Elements are substances that cannot be broken down into any simpler substances. Hence they cannot be broken down by chemical methods. They may change in appearance if physical methods, but chemically, they still remain as the element.
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.
Substances are changed into different substances when bonds break and form during?
Chemical bonds are made and broken by chemical reactions. After chemical bonds have been broken, then energy is released, and if a chemical bond is made, then energy is absorbed.
What any substance cannot be broken down into simpler substances?
This change is possible.
Can sodium be decomposed by a chemical change?
No. Sodium is an element and elements cannot be broken down (decomposed) by a chemical change.
Substance that cannot be changed into simpler substances by chemical means?
Elements cannot be changed into simpler substances by chemical means. To change them into simpler particles, you need nuclear means.
If a chemically pure substance that cannot be broken down into smaller substances?
A chemically pure substance is a substance that cannot be separated expect by chemical means. For instance, water can be broken down by electrolysis into oxygen and hydrogen. Yet, it is still a pure substance because a chemical change must occur in order for this to happen.
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.
This is a process in which substances change into new substances with different properties?
Chemical Change
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.
What is a substances that undergo a chemical change?
Substances that undergo chemical change are called reactants.
