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 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.
Why are elements and compounds considered as substances?
Elements and compounds are considered substances because they have distinct chemical properties and compositions. Elements are pure substances made up of only one type of atom, while compounds are composed of two or more different types of atoms chemically bonded together. Both elements and compounds have specific physical and chemical characteristics that distinguish them from mixtures.
How do you separate mixtures and compounds?
You can break down a mixture by physical means
What would be regarded as compounds?
Compounds are substances formed by the chemical bonding of two or more elements. Examples include water (H2O) and sodium chloride (NaCl). Compounds have a fixed chemical composition and can be broken down into simpler substances through chemical reactions.
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 be broken down only 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.
Why compounds can not be broken down inti its constituent element by physical mrthod?
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.
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.
Can compounds may be broken down into elements in a chemical change?
yes they can
Can compounds be broken down into elements by physical means?
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.
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 are substances with constant composition that can be broken down into elements by chemical processes?
Compounds are substances with constant composition that can be broken down into elements by chemical processes. For example, water (H2O) is a compound that can be broken down into hydrogen and oxygen through chemical reactions.
What is 3 differences between compounds and 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).
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.
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.
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.
