How you prepare 0.02 M KCl solution?
I'll straightly go to the equation. KCL molar mass is 74.5513 g/mol. To prepare 0.02 M KCL solution, *0.02 M is also known as 0.02 mol/litre. 74.5513 g/mol x 0.02 mol/litre x 1 litre = 1.4910 g *note that in the equation we can cancel the mol and litre leave out the gram alone. So we need only 1.4910 g of KCL in 1 litre. You can change the volume, depend on your convenience but must in litre unit.
Is water condensing a physical or chemical change?
Water condensing is a physical change. It is a change in state from the gaseous phase (water vapor) to the liquid phase (liquid water) without any change in the chemical composition of water molecules.

Which equation represents a physical change?
Burning coal is a chemical reaction, a chemical change; but the solid reactant is transformed in gaseous products (H2O and CO2) - this is a physical change.
Is adding water to lemonade physical or chemical change?
Physical because, the lemonade dissolves into the water, without creating any of the chemical changing results.
What dissolves toothpaste besides water?
Any liquid will have the same effect on toothpaste as water.
What dissolves quicker in water?
Any ionic salts dissolves in water quickly.(Like NaCl, Sodium Chloride) as water is a polar solvent. The salt ionizes in water quickly than sugar.
When table salt is added to water the ionic compound dissolves. Does this represent a physical change or a chemical change?
Dissolving table salt in water represents a physical change, not a chemical change. The salt molecules remain intact and simply disperse in the water, without any chemical bonds being broken or formed.
What color change do you see when AgNO3 is added to water and why does this happen?
A pure and fresh solution of silver nitrate is clear.
What ions would you find when an base dissolves in water?
A base is any substance that forms hydroxide ions in water.
What color is it when you mix water and calcium chloride?
What happens when you mix water and calcium chloride?Water colour does not change
How does methanol dissolve in water?
Methanol dissolves in water because of its polar nature. Methanol molecules have a hydroxyl group that can form hydrogen bonds with water molecules, facilitating their interaction and resulting in a homogeneous mixture.
When a substance dissolves it undergoes a chemical change physical change molecular change?
When a substance dissolves, it undergoes a physical change, not a chemical change. This is because the molecules of the solute are dispersed in the solvent but do not undergo any chemical reactions. The process of dissolving is a result of the attraction between the solute and solvent molecules.
What has the ability to bond water to itself?
The cause is the formation of hydrogen bonds between water molecules.Any hydrophilic molecule that dissolves in water make H-bonding with water molecules
