When a substance changes into a different substance a blank change has occurred?
If form changes but identity doesn't change then it is a physical change.
Is magnesium physical change or chemical change?
Magnesium is not a change of any sort. It is a metallic element that can undergo both physical an chemical changes.
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.
Is potassium a physical or chemical change?
Potassium is not a change; potassium (K) is a chemical element.
Can NE be decomposed by chemical change?
no
Can an element be decomposed by chemical change?
Yes, an element can be decomposed into simpler substances through chemical reactions. This typically involves breaking the chemical bonds that hold the element's atoms together, resulting in the formation of new compounds or elements.
Can sodium be decomposed by a chemical change?
No. Sodium is an element and elements cannot be broken down (decomposed) by a chemical change.
Is toasting of bread a physical or chemical change?
Physical ------------------- It is a chemical change because some compounds from bread are thermally decomposed. The reaction is not reversible.
Is a Toasting a piece of bread a chemical change or physical change?
It is a chemical change because some compounds from bread are thermally decomposed.
Can HF be decomposed by a chemical change?
No, hydrofluoric acid (HF) cannot be decomposed by a chemical change because it is a stable compound. Physical methods are typically used to separate HF into its constituent elements.
What is the difference between a chemical change and physical change?
A physical change changes the physical properties of an element like color where chemical changes change the chemical properties of an element and usually can't be undone.
Is melting a phyical or chemical change?
Physical. Melting is always a physical change.
When a substance changes into a different substance a blank change has occurred?
If form changes but identity doesn't change then it is a physical change.
Carbon that cannot be decomposed a physical property or a chemical property?
Carbon that cannot be decomposed is a chemical property. It is related to the chemical bonds and composition of the substance, indicating that the carbon atoms are tightly held together in a way that resists decomposition through physical means.
Is sodium a physical or chemical change?
Sodium is a chemical element, not a change.
Is iron a chemical or physical change?
Iron is a chemical element, not a "change".
Is an iron a chemical or physical change?
Iron is a chemical element, not a "change" !
