Compound is a substance that consists of two or more elements which are chemically bonded. They can only be separated by using chemicals or other means. however mixture can be separated by physical means.
they are both elements, they cant b broken down by chemical means!
The rotting of leaves is a chemical change because the breakdown of the leaves involves a chemical reaction to decompose the organic matter, resulting in the formation of new substances such as water, carbon dioxide, and various compounds.
Cooking an onion involves both chemical and physical changes. The heat causes physical changes such as softening and browning of the onion as well as chemical changes such as the breakdown of complex molecules into simpler compounds, resulting in new flavors and aromas.
Ionic compounds such as sodium chloride (NaCl) and metallic compounds like steel do not exist in independent molecular form. These compounds are made up of ions or atoms arranged in a lattice structure, rather than discrete molecules.
Hydrogen is essential for life as it is a key component of water and organic molecules such as proteins and DNA. Without hydrogen, these essential compounds would not exist, resulting in the inability of living organisms to survive. Additionally, hydrogen plays a crucial role in energy production and various metabolic processes in living cells.
Mixtures can be separated by physical methods.
actually it is a CHEMICAL change...because physical means you cant reverse the compounds like plaster of Paris mixed with vinegar turns hard but is an experiment that you cannot reverse back!! xxx
A compound is a simple substance, a mixture is formed from two or more compounds.
A substance that cannot be separated by physical change is a pure substance. This includes elements and compounds. In a pure substance, the individual components are chemically combined, making it impossible to separate them without a chemical reaction.
you cant. eat it
they are both elements, they cant b broken down by chemical means!
replace it. cant be fixed.
He cant fly because his balance would be bad, they cant fly
you cant
an element
kno you cant
no it cant
