State two quantitative physical proparties that change when antifreeze is dissolved in water?
It chances the boiling point of the water, and it changes the freezing point of the water
What physical property of salt changes when the salt is dissolved in water?
don't know look in your science book
Is antifreeze an electrolyte or a nonelectrolyte?
Antifreeze is a nonelectrolyte because it does not dissociate into ions when dissolved in water.
How could you explain that the change that take place in when salt is added to water is physical change?
It is a physical change because when salt is added to water,it is dissolved in it which only changes its physical appearance.
Do the physical properties of water change when a compound is dissolved in water. If so which properties change and why?
Yes, when a compound is dissolved in water, properties such as boiling point, freezing point, and density can change. This is because the presence of the dissolved compound changes the interactions between water molecules, affecting the overall behavior of the solution.
What is a property of pure salt that changes when it is dissolved in water?
Firstly, pure salt is white and it becomes colourless when dissolved in water. Secondly, solid salt is a non-conductor of electricity, whereas the solution is an electrolyte and conducts well.
Is antifreeze ionic or molecular?
Antifreeze is a molecular compound because it is composed of covalent bonds between its atoms. It does not dissociate into ions when dissolved in water.
If there is an antifreeze leak would it stop leaking antifreeze and then leak water?
No. they're dissolved in each other and are quite hard to seperate.
A type of chemical weathering in which minerals react with dissolved oxygen in water is known as?
Physical weathering is a type of weathering in which minerals react with dissolved oxygen in water. This causes chemical changes to take place in the minerals.
Is the taste of salt in water a physical or chemical change?
The taste of salt in water is a physical change. Dissolving salt in water does not create a new substance; it just changes the physical state of the salt from solid to dissolved in the water.
What is physically happening when water is dissolving a substance?
when we dissolve a substance then first of all there may occur physical change like shape,colour,temperature etc. these changes are called physical changes.
Solid forms into dissolved water is a chemical or physical change?
Dissolving in water is a physical change.
