No, it takes the same number of water molecules to fill up a certain space whether they are in the form of ice or liquid water. In ice, the water molecules are just held in a more structured arrangement compared to the more freely moving molecules in liquid water.
the molecules are donated to water molecules. if a little of the acid remains after it is added to water, then it is a strong acid. if a lot remains, then it is a weak acid. same goes for bases.
The molecules in water are not tightly packed as such flow and spread very easily but when the water turns to ice the molecules in the liquid enlarge ans they tightly packed and thus, when water turns to ice new molecules are not formed.
When ice melts, the chemical composition remains the same. Ice is just the solid state of water, so when it melts, it turns into liquid water. The molecules in ice rearrange themselves into a more disordered state to become liquid water, but the chemical makeup of the water molecules themselves does not change.
When salt dissolves in water, the amount of salt stays the same. The salt molecules spread out in the water but remain present in the solution. This is a physical change and does not involve the loss or gain of salt molecules.
Nothing they stay the same - their density changes.

it will fizz because the vibration will shake the water and create a motor effect
ice melt at 0 degrees and water freeze at the same temperature because it cool like that. xDThe real answer is because molecules of ice are constantly escaping into the water (melting), and molecules of water are being captured on the surface of the ice (freezing).
If they are both under the same pressure and are the same in volume, then, yes, warm air has fewer molecules
When sucrose is dissolved in water, the sucrose molecules break apart into individual glucose and fructose molecules. These individual molecules become surrounded by water molecules, forming a solution. This process is a physical change, as the chemical composition of the sucrose molecules remains the same even though they are now dispersed throughout the water.
The cool air blowing from the AC cools the water vapors, condensing to form water droplets on the window. Same thing happens on a cold glass of water. This is explained in the water cycle.

When sugar is stirred into water, the sugar molecules dissolve in the water molecules. This creates a solution in which the sugar molecules are evenly distributed throughout the water. The presence of sugar in the water stimulates sweet taste receptors on the tongue, giving the sensation of sweetness.
First let's get a little science lesson. I'm sure you all know that matter has three states: solid, liquid and gas. If you heat a solid where the molecules are tightly packed together up enough, it melts, right? That's because the molecules have been given energy and are now more spread out liquid molecules. The same thing happens when you cool down a gas or liquid, just the molecules start to slow down and gather closer together. So, back to the water vapor in the can. The gas molecules slow down enough that they will condense, or turn into a liquid.
Nope, All molecules are different. They might look the same, but they aleast have thing different.
