Are compounds broken down into elements by chemical or physical change?

its a chemical change.
a physical change does not change the chemical makeup of a substance. it simply changes its form or physical state. examples: ice melting, a tree being chopped down.

∙ 11y agoIt is a chemical change: the original compound was actually a different substance, not merely a mixture of the elements. This is a type of "decomposition" chemical reaction.
*Note that "alloys" of metals are mixtures, not compounds, because although they display altered properties, they can be separated by physical means (smelting).

∙ 9y agoThe conversion of compounds into elements is a chemical change. A chemical change involves the breaking of bonds between atoms.

What substances cannot be broken down into any other substances by physical or chemical means?
All substances can be broken into any other substances (or elements) by chemical or physical methods.
What is a substance that cannot be broken down into other substances by ordinary chemical methods?
compounds CAN be decomposed elements CANTThe answer would be Mercury because it is an element and can't be broken down by chemical means. but methane, ethanol and ammonia can be broken down by physical means because they are compounds.
Cannot be broken down or changed in any physical chemical or electrical way?
elements
Does chemical change make a compound?
Not necessarily. In some chemical changes a compound is broken down into its elements.
How do you separate mixtures and compounds?
You can break down a mixture by physical means
Can compounds be broken down only by chemical means?
yes, they can only be broken down by chemical means
How do compounds differ from elements?
Compounds are made up of 2 or more elements.Compounds can be broken down into simpler substances by chemical means, but elements cannot.Compounds are made up of 2 or more elements. Compounds can be broken down into simpler substances by chemical means, but elements cannot.
Elements and compounds cannot be broken down into simpler substances by an ordinary what?
Elements and compounds (pure substances) cannot be broken down by physical changes.
Can compounds may be broken down into elements in a chemical change?
yes they can
Can elements be split up into simpler substances by heating them?
While some compounds do degenerate to their elements when heated, almost none do.
How do compaunds deffer from elements?
Compounds are made up of 2 or more elements. Compounds can be broken down into simpler substances by chemical means, but elements cannot.
How are elements and compound different?
Elements are made up of only one thing. While a compound is made of two of more elements. Here is an example. H2O. Water is hydrogen and oxygen.
What substances cannot be broken down into any other substances by physical or chemical means?
All substances can be broken into any other substances (or elements) by chemical or physical methods.
What are properties of elements compounds and mixtures?
Here are some characteristics of compounds:Compounds are made up of 2 or more elements and they are all chemically bonded.The properties of a compound are different from the elements that make it up.Compounds can be broken back into elements by chemical reaction, exposure to light, etc.Compounds can be separated only chemically, not by physical meansThe mass of the compound is determined by the mass of the elements that make it up.When compounds are formed heat and light is given out or absorbed.Compounds have definite proportions.
What are substances with constant composition that can be broken down into elements by chemical processes?
This is the compound, which consits of at least two elements.
What is a substance that cannot be broken down into other substances by ordinary chemical methods?
compounds CAN be decomposed elements CANTThe answer would be Mercury because it is an element and can't be broken down by chemical means. but methane, ethanol and ammonia can be broken down by physical means because they are compounds.
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.
