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.
no, it's a mixture. Salt is a pure substance, as is water, but together they are a mixture.
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.
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!
The molecule of water remain unchanged, and also the percentage of hydrogen.
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.
definitly salt
yes, because salt is polar molecule
no, it's a mixture. Salt is a pure substance, as is water, but together they are a mixture.
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.
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.
Fresh water contains no sign of salt, while on the other hand salt water contains salt
yes
95% of Earth's water contains high concentration of salt, or high salinity

There are a few different types of salt in salt water, though the salinity of the oceans differ in different locations because the salt comes fromdifferent locations and from the currents moving in the water that carry 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.
