Polar molecules.
Not everything dissolves in water. Substances like oil and plastic do not dissolve in water because they are nonpolar, while water is a polar molecule. Only substances with similar polarity can dissolve in water.
"like dissolves like" is an expression used by chemists to remember how some solvents work. It refers to "polar" and "nonpolar" solvents and solutes. Basic example: Water is polar. Oil is non-polar. Water will not dissolve oil. Water is polar. Salt (NaCl) is also polar. Like dissolves like, so polar dissolves polar, so water dissolves salt.
It depends on the specific mixture. Some mixtures can dissolve in water while others may not dissolve. The solubility of a substance in water depends on factors such as the nature of the substances involved and the temperature of the water.
The candy shell will readily dissolve in water, but the chocolate center dissolves much more slowly. It'll take a while.
To put it simply like dissolves like when it comes to polar and non-polar solutes/solvents. Water is polar so it dissolves polar things.
Cooking oil is nonpolar, while water is polar. Like dissolves like, meaning substances with similar polarity tend to dissolve in each other. Since oil is nonpolar and water is polar, they do not interact on a molecular level, causing oil to not dissolve in water.
Yes, coffee can dissolve. How else would youu make coffee with a coffee pot? Usually coffee takes a while to dissolve in cold water but it will not take long to dissolve in hot water. Made by Olivia Doherty
Salt (sodium chloride) and sugar (sucrose) are two common materials that dissolve in water. Salt dissolves easily in water due to its ionic nature, while sugar dissolves in water because its molecules are polar and interact with the water molecules.
Metallic bonds do not dissolve in water because they are strong bonds formed between metal atoms, while water dissolves compounds through interactions like hydrogen bonding or ion-dipole interactions. Metallic bonds are not broken by water, so metals typically do not dissolve in water.

Whether a solid or liquid dissolves in water depends on its chemical properties. Solids that have polar molecules or ionic compounds typically dissolve well in water due to the attraction between water molecules and the solute. Liquids that are polar, like alcohol, can also dissolve in water, while non-polar substances, such as oils, do not dissolve because they lack the necessary interactions with water molecules. The principle "like dissolves like" often applies, indicating that similar polarities will lead to solubility.
There exists at least one (actually, a lot more than one) powder that dissolves in water. However, not every powder dissolves in water. It wasn't clear which of the two you were trying to ask.
