What substance can be decomposed by a chemical change Ne N2O HF or H2O?
The substance that can be decomposed by a chemical change is N2O (nitrous oxide) because it undergoes a decomposition reaction when exposed to heat or a catalyst, breaking down into its constituent elements nitrogen and oxygen.
Is the chemical formula H2o physical or chemical change?
The chemical formula H2O represents water. It is a chemical formula that describes the composition of a substance, in this case, water. Therefore, it is related to a chemical change rather than a physical change.
Can h 2 o be decomposed by chemical change?
Yes, water (H2O) can be decomposed by chemical change through a process called electrolysis. Passing an electric current through water can split the water molecules into hydrogen gas (H2) and oxygen gas (O2) through the reaction: 2H2O → 2H2 + O2.
Which substance can be decomposed by chemicals means?
Compound is a substance composed of two or more elements combined in definite proportions, can be broken down by chemical means. Element is a substance that cannot be broken down into simpler substances even by chemical means.
Is an ice cube and water a physical or chemical change?
A physical change because the substance does not change. It is still H2O, but in a different form.

Is this a chemical change or physical change water freezes and turns into ice?
It's a physical change because the substance is the same before and after only changing form. In other words, water's chemical formula is H2O and ice's chemical formula is also H2O, so they are the same substance. Therefore it is a physical change.

What is a physical change rather than a chemical change?
`A physical change is one in which matter is changed into another physical state without changing its chemical constitution(eg-ice melts to water,in both case substance is H2O).A chemical change is where there is a chemical change of the substance during the process(eg-CaCO3 is heated to form CO2 and CaO,here the new substance formed is unrelated chemically to parent substance.)
What chemical substance is formed when the -OH and -H are joined?
H2O is the chemical formula of water.
What is the most abundant chemical substance in the human body?
This substance is water, H2O.
Is the freezing of H2O a chemical or physical change?
Freezing of H2O is a Physical Change.
Is ice cube a physical change or chemical change?
It is a physical change because if the H2O
Is an ice cube and water a physical or chemical change?
A physical change because the substance does not change. It is still H2O, but in a different form.
Is perfume evaporating chemical or a physical change?
Physical as H2O and some other elements are only removed from the perfume istead of creating new substances Physical, because H2O and other chemical substances are removed instead of new chemical substance being created.
