No. If two elements can be separated by a physical process then they are simply mixed.
yes it can
FALSE It is true the above answer is wrong
A chemical change occurs because compound is two elements put together so when they are separated it forms a new substance.
Yes, but not physically, only chemically. Part of the definition of a compound, as opposed to a mixture or solution, is that compounds can only be separated back into their respective elements through a CHEMICAL process.
When two elements chemically bond to form a compound, it is known as a chemical reaction. During this process, atoms from each element combine to form new molecules with different properties than the original elements.
It can be seperated by physical process
Elements
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.
no, it can not be separated by a physical process.
Yes, but the process is not always easy. In some case a lot of energy might be needed. For example, electrolysis can separate Na and Cl from NaCl but it has to be done at high temperatures using molten NaCl.
yes it can
FALSE It is true the above answer is wrong
1. Mechanically removing: physical process 2. Chemically removing: chemical process
A chemical change occurs because compound is two elements put together so when they are separated it forms a new substance.
The process of making hydrogen from water involves both physical and chemical transformations. Physically, water molecules are separated into hydrogen and oxygen through a process called electrolysis. Chemically, this separation involves breaking the bonds between hydrogen and oxygen atoms, resulting in a chemical change.
The decomposition is a chemical process.
There are several ways in which elements can be separated by physical methods. Centrifuge If you grind an ore to sufficient fineness, you can use a centrifuge to separate an element based on its specific gravity. Panning is a more primitive version of this basic method. Gaseous Diffusion You can also heat an ore to the temperature at which a particular element becomes gaseous and separate it out.
