No it isn't
False. When an ionic solid mixes with water, the solute breaks down into ions, not individual molecules. This process is known as dissociation, where the ionic bonds are broken, and the ions are surrounded by water molecules.
Technically false; it's full of virtual particles, photons, gravitons (if they exist), and possibly other gauge particles. However, if this is a homework question and you're not in university physics, the answer your teacher is probably looking for is "true."
True. When water boils, the intermolecular hydrogen bonds between water molecules are broken, allowing them to escape as vapor.
False. When a molecular solid mixes with water, the solute typically breaks apart into individual ions or molecules, rather than breaking down into individual molecules. This process is known as dissociation.
False. Chilling a liquid will actually decrease evaporation at the surface because lower temperatures slow down the movement of molecules, reducing their ability to escape into the air.
False, when water is boiled the water particles actually start to bounce. The particles start to move rapidly bouncing off each other and the object they are inside. Ice the particles slow down and start to get closer and become solid form.
It is false that the loss of electrons from food molecules is reduction. Electrons are negatively charged subatomic particles.
Water particles move in circles
False. More runoff can actually lead to more erosion, as the increased water flow can carry away soil particles and contribute to erosion.
Yes, that's correct. In a double replacement reaction where water is produced, the total number of solute particles remains the same, but the number of solvent particles (water molecules) decreases because some of them are consumed in the reaction to form the product.
True
False. When sugar is dissolved in water, it is a physical change where the sugar molecules are dispersed in the water but no chemical bonds are formed between them.
False. When an ionic solid mixes with water, the solute breaks down into ions, not individual molecules. This process is known as dissociation, where the ionic bonds are broken, and the ions are surrounded by water molecules.
Soy sauce dissolves in water due to its composition of water-soluble compounds such as sodium chloride, amino acids, and sugars. These molecules have polar groups that interact with water molecules through hydrogen bonding, allowing the soy sauce to evenly disperse throughout the water. This process is known as dissolution, where the water molecules surround and separate the soy sauce molecules, breaking them down into smaller particles that are dispersed throughout the solution.
Technically false; it's full of virtual particles, photons, gravitons (if they exist), and possibly other gauge particles. However, if this is a homework question and you're not in university physics, the answer your teacher is probably looking for is "true."
True. When water boils, the intermolecular hydrogen bonds between water molecules are broken, allowing them to escape as vapor.
False. There will still be movement of water molecules across the membrane, but there will be no net movement. This means that the number of molecules coming into the cell will equal that going out, and equilibrium will therefore be maintained.
