Is pure water a compound or a mixture?
Pure water is a compound of hydrogen and oxygen.
What substance cannot be separated physically but can be separated chemically?
A compound, such as water (H2O), cannot be physically separated into its component elements (hydrogen and oxygen) but can be chemically separated through a chemical reaction, such as electrolysis, which breaks the bonds between the elements.
How will you justify that water is a compound not a mixture?
Water is a compound formed by chemical combination of Hydrogen and Oxygen. Chemical properties are changed in water, therefore it is a compound. also, in water, hydrogen and oxygen are in a fixed proportion by weight i.e. 1:8. these are not the properties of a mixture.
What compound is formed between hydrogen and fluorine?
This compound is the hydrogen fluoride HF.
How can the parts of a mixture and compound be deprecated?
The components of a mixture can be separated through physical methods, such as filtration, distillation, or chromatography, as the substances retain their individual properties. In contrast, the parts of a compound cannot be separated by physical means because they are chemically bonded together, requiring chemical reactions to break those bonds. For example, water (a compound) can only be separated into hydrogen and oxygen through electrolysis. In summary, the separation methods depend on whether the substances are physically mixed (mixture) or chemically combined (compound).

When water molecules are broken down into hydrogen and oxygen molecules by an electric current is this an example of a mixture?
no, it is a compound
Can water catch fire?
No, water itself cannot catch fire because it is a compound made of hydrogen and oxygen. However, the hydrogen in water can be ignited and burn if it is separated from the oxygen.
Can an electric current break down a compound?
Yes. For instance, electrolysis breaks down water into hydrogen and oxygen.
Can water catch on fire?
No, water itself cannot catch on fire because it is a compound made of hydrogen and oxygen. However, the hydrogen in water can catch on fire if it is separated from the oxygen and ignited.
How can a compound be separated?
Yes. For example, water can be separated into oxygen and hydrogen gas by the chemical process of electrolysis. Molten sodium chloride can also be separated into sodium metal and chlorine gas by electrolysis.
Can a compound be broken down by electricity?
Yes, a compound can be broken down by electricity through a process called electrolysis. In electrolysis, an electric current is passed through a compound to split it into its individual elements or ions. This can be used to separate elements or create new compounds.
Is hydrogen cyanide a element compound or mixture?
Hydrogen flouride is a compound.

What is the type of compound of hydrogen sulfide ionic or covalent or polar covalent?
polar covalent compound, although the difference in electronegativity is not enough to form dipole, the assymetry of the compound structure causes it to gain polarity.
Phosphoric acid is element or compound or mixture?
A compound. H3PO4 is the formula for phosphoric acid. It is a compound of three separate elements. It is a compound, not a mixture since it cannot be separated by physical means.
