is separating water into hydrogen and oxygen a physical or chemical separation?
physical. i am in 6th grade. well can u help me and go to the general wuestions and answer math help plz
The answer is a Chemical change
Who knows?
Separating water into hydrogen and oxygen can be considered both a physical and a chemical separation. Let me explain why.
When we apply an electric current to water using a process called electrolysis, the water molecule (H2O) undergoes a chemical reaction. This reaction breaks down the water molecules into their constituent elements, hydrogen (H2) and oxygen (O2). This process involves the breaking of chemical bonds within the water molecule and forming new bonds between hydrogen and oxygen atoms.
So, from a chemical perspective, it is a separation that involves a chemical reaction.
However, from a physical perspective, it can also be called a separation since we are physically separating the hydrogen and oxygen gases from each other. We collect the hydrogen gas at the cathode and the oxygen gas at the anode during the electrolysis process.
So, to summarize, the separation of water into hydrogen and oxygen involves both a chemical reaction and a physical separation.
