Table salt, or NaCl, does not form molecules - rather, it is a collection of Na+ and Cl- ions in a 1:1 ratio, hence the name "ionic compound".
Water, or H2O, is a molecule. It consists of two hydrogen atoms covalently bonded to a central oxygen atom.

Why does salt dissolve and sand doesn't?
Water is a polar molecule. you may have heard water being called H20. This is because it has two hydrogens (slightly positively charged) and one oxygen (slightly negatively charged) in a molecule. Salt/Sodium Chloride/NaCl is also polar and that is the reason why it dissolves in water. Sand doesnt because it is not a polar molecule, it is just crushed rock. Hope that helps!
Is there more hydrogen in salt water than in fresh water?
The molecule of water remain unchanged, and also the percentage of hydrogen.
Contrast salt water and fresh water?
Fresh and salt water are very different for one key reason, fresh water doesn't contain salt and salt water obviously does. There are different flora and fauna in fresh and salt water for this reason.
What can molecules do when dissolved in water?
Students will make a 2-D model of a salt crystal and use water molecule cut-outs to show how water dissolves salt. After seeing an animation of water dissolving.
Why salt water is more cohesive than tap water?
zeus is the king of dolphins
In salt water with molecule is bigger the salt or the water?
definitly salt
Are water salt and rust elements?
None of those are. Water is made of two hydrogen molecules and one oxygen molecule. Table salt is one sodium molecule and one chloride molecule (Other types of salt have different molecules but all of them have sodium. That is why MSG which is mono sodium glutamate is listed in your sodium intake). Sugar is definitely not one element. It is a lot of different types of elements put together. So many I can't remember what it is but I remember there are 11 molecules of a certain element.
Does the temperature affect the speed at whih the salt dissolves in water and why?
yes, because salt is polar molecule
Why does salt water work better in the process of electrolysis?
Salt water works because electricity needs a conduit to get electrons from one place to another. Salt is a molecule that is able to do this when it is dissolved in water.
How is fresh water different from ocean water?
Salt water has salt water in it and is bad for you, fresh water has no salt water in it and is good for you.
Is Every molecule of water is different from every molecule of sugar?
yes
What type of substance is saltwater?
95% of Earth's water contains high concentration of salt, or high salinity
How salt water different from fresh water?
Fresh water contains no sign of salt, while on the other hand salt water contains salt
Do salt attract water?
Yes, salt does attract water. Water is a polar molecule. Sodium chloride also carries charge on it so it will dissolve in water. "Like dissolves like"

What are the results of the project what evaporates faster salt water or fresh water?
pure water evaporates faster because it has a higher vapour pressure than salt water. Raoult's Law. The attraction between salt ions and water is stronger than that of water molecules. It therefore takes more energy to separate a water molecule from salt, that a water molecule from another water molecule.
What is water when salt is dissolved in it?
The water doesn't change. However, the salt splits into an anion and a cation. Those ions become surrounded by the water, thus making them no longer visible. But the water is still just water.
