What else can I help you with?
Why water is regarded as a compound although it can be separated into hydrogen and oxygen by passing an electric current?
The property of copounds is that they can be seperated only by hemical means and not by physical means. Water is a compound since it cannot be seperated by physical means. Seperation into hydrogen and oxygen is a chemical mean.
Is combing alcohol with water a chemical change?
Mixing is a physical process.
Can salt and water be seperated by filtering?
In short, yes
Can mixtures be separated by physical change?
Some mixtures can be separated by physical changes. For example distilling alcohol can be done by heating the mixture to between the boiling points of water and alcohol, so the alcohol boils off, leaving the water. The alcohol is then condensed into another container.
Why mixing of sugar into water is chemical change?
First and for most, sugar mixing in water is not a chemical change. It is a physical change (Something which can be gotten back) Water and sugar, once mixed, can both be seperated by heated the liquid. The water evaporates, thus the sugar is left behind. Hope i helped. Chao!

Is sugar dissolved in water a chemical or a physical change?
it s a physical change.
Is the fact that isopropyl alcohol mixes with water a physical or chemical property?
The fact that isopropyl alcohol mixes with water is a physical property. It is based on the physical interactions between the molecules of isopropyl alcohol and water, without any chemical change taking place.
Can a compound be seperated into its consistent elements by physical methods?
Yes it can. Water, table salt, and sugar are all examples of compounds and can all be decomposed into simpler substances through physical means.^^ I believed that water and table salt would be a mixture, mixtures are the non-chemical means not compounds, with compounds there is a chemical change.
Mixtures can be seperated by physical changes?
Yes, some mixtures may be separated by a physical change. A mixture of water and alcohol may be separated by heating. The salt from sea water may be separated by slow freezing - as happens in polar ice sheets. And most ores are a complex mixture, and the target metal may be separated by simple physical changes.

What is an exaple of physical change?
A type of change in which the form of matter is changed to another form is called a physical change. Thus the chemical change does not occur, but only a physical change occurs in it. Example: When ice melts into water When water is boiled, and it changes into water vapor.
How does alcohol react to heat?
When alcohol is heated, it evaporates at a lower temperature than water. This means that when alcohol is heated, it will turn into vapor more quickly than water.
Will objects float better in rubbing alcohol or water?
Objects will float better in rubbing alcohol than in water because rubbing alcohol has a lower density than water. This means that objects will displace less liquid in rubbing alcohol, making it easier for them to float.
