Is dissolving NaCl in h2o a chemical change?
No, it is a physical change.
Is Chemical formula H2O Chemical Or Physical Properties?
Neither. It defines the substance but does not characterize it.
Is adding NaOH to HCL chemical or physical change?
It is a chemical change. NaCl + H2O
Is heat changing H2o to steam a physical or chemical change?
Physical change- it is still H2O, and can be changed back to water by cooling it.
Is evaporation physical or chemical change?
it is a physical change because it is not making a new substance. It is just changing the size/shape
When water evaporates into a stream is it a physical change?
Physical change. The chemical formula of the steam still remains as H2O.
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.
Is ice melting at 0 degrees Celsius a chemical property?
a physical change, it's chemical formula is still H2O
What is the chemical formula for the liquid ice?
It isn't. The melting of ice is a phase change, which is a physical change because the chemical composition of the water does not change.
Is melting ice into water a chemical change?
No. It is a physical change. The chemical formula for water is H2O, and that is also the chemical formula for ice. So there is no chemical change taking place, only a change in the state of matter.
Is the freezing of H2O a chemical or physical change?
Freezing of H2O is a Physical Change.
Is chemical formula H2O physical or chemical property?
H20 has both chemical and physical properties.
Melting ice. Chemical or physical change?
Physical. H2O is still H2O.
NaCl H2O- physical or chemical change?
Physical
Is burning of branches physical change?
No, it's a chemical reaction with O2.In physical changes the chemical formula remains the same; like ice (H2O) and water (H2O). Burning wood is something like cellulose + O2 --> CO2 + H2O
Is drying water chemical change or physical change?
Physical, it is still H2O
Is dissolving NaCl in h2o a chemical change?
No, it is a physical change.
