yes, they can only be broken down by chemical means
Compounds can be broken down by both chemical and physical means. Chemical means involve breaking the bonds between atoms, resulting in a new substance. Physical means do not involve changing the chemical makeup of the compound, but rather breaking it into smaller pieces.
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.
By chemical methods, such as electrolysis.
A material that can be broken down by chemical methods is considered as a "chemical decomposable material." These materials can be broken down into simpler compounds or elements through the application of specific chemicals or chemical reactions. Examples include organic compounds like plastics or polymers that can be broken down through processes like hydrolysis or oxidation.
No, compounds cannot be broken down into elements by physical means because compounds are composed of atoms that are chemically bonded together. Physical means can only change the physical state of matter, such as melting or evaporating a compound, but it does not break the chemical bonds between the atoms.
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.
You can break down a mixture by physical means
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.
An element is only made up of its protons, neutrons and electrons.A compound is made up of elements.A compound can be broken down into to its original elements easier than an element can be broken into its (protons, neutrons and electrons).
The simplest substance that you can obtain by ordinary means is an element.An element is a substance than cannot be separated or broken down into simpler substances by chemical means.
A mixture There are four types of mixtures: Alloy - homogenous metalic solid Solution - homogenous mix of two or more substances (not all metals) Suspention - not evenly mixed and will separate if left alone Colloid - Sorry, I always forget what this one is
Compounds cannot be broken down into their constituent elements by physical methods because the bonds holding the elements together in a compound are chemical bonds, which require chemical reactions to break. Physical methods only involve changes in state or appearance of matter, not in its chemical composition. Breaking down a compound into its elements requires breaking these chemical bonds, which can only be achieved through chemical reactions.
