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.
Which two substances cannot be broken down by chemical change?
Two substances that cannot be broken down by chemical change are elements and compounds. Elements are fundamental building blocks of matter that cannot be broken down into simpler substances by chemical reactions. Compounds are made up of two or more different elements chemically bonded together in fixed ratios, and they also cannot be broken down into simpler substances by chemical reactions.
What is elements plus compounds?
Elements are substances made up of only one type of atom, while compounds are substances made up of two or more different types of atoms bonded together. Elements cannot be broken down into simpler substances, while compounds can be broken down into their constituent elements through chemical reactions.
How is matter organized into substances mixtures elements and compounds?
Matter is organized into substances, which are either mixtures (combination of two or more substances) or pure substances. Pure substances can be elements (composed of all the same type of atom) or compounds (composed of different types of atoms bonded together in fixed ratios). Elements cannot be further broken down by chemical means, while compounds can be broken down into simpler substances by chemical reactions.
How did lavoisier distinguish between compounds and elements?
Lavoisier distinguished between compounds and elements by conducting experiments to show that compounds can be broken down into simpler substances, while elements cannot be further broken down by chemical means. He also proposed the Law of Conservation of Mass, which states that the total mass of substances present before a chemical reaction is equal to the total mass after the reaction, providing further evidence for the distinction between compounds and elements.
Substances that can be broken down into simpler substances are called?
compounds
What are substances that can be broken down into simpler substances?
Chemical compounds.
What are substances that can be broken down to simpler substances?
Chemical compounds.
What type of reaction occurs complex compounds are broken down into simpler substances?
decomposition
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.
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.
Why aren't compounds and elements the same?
Compounds are made of two or more substances joined together, and elements are a pure substance that can't be broken down into simpler substances.
What are the differences between atoms and compounds?
both are pure substances, but atoms represent the smallest bits of elements. compounds are chemically combined atoms, molecules represent the smallest bits of compounds. atoms cannot be broken down into simpler substances, compounds can be broken down into atoms.
Can a liquid be broken down into simpler substances?
It depends on the liquid. As an example, bromine and mercury are elements and can not be broken down into simpler substances.
What type reaction occurs when complex compounds are broken down into simpler substances?
This kind of reaction is called "decomposition".
Which two substances cannot be broken down by chemical change?
Two substances that cannot be broken down by chemical change are elements and compounds. Elements are fundamental building blocks of matter that cannot be broken down into simpler substances by chemical reactions. Compounds are made up of two or more different elements chemically bonded together in fixed ratios, and they also cannot be broken down into simpler substances by chemical reactions.
The substances that can not be broken down into simpler substances are called?
elements
