What else can I help you with?
What is the product of water plus sodium chloride?
Sodiumchloride is dissociated in water: NaCl-------Na+ + Cl-
What happened when the lye dissolve in the water in terms of energy?
When lye dissolves in water, it releases energy in the form of heat. This process is exothermic, meaning that energy is released as the lye particles interact with the water molecules, forming a strong, alkaline solution.
What makes solids typpically dissolve faster in hot water?
When solids dissolve in water, their closely packed, crystal lattice breaks. To break this crystal lattice, some amount of energy known as lattice energy must be supplied to the crystal (solid). Hot water molecules have more kinetic energy in them, hence they can impart more energy per collision to the molecules, hence solids dissolve faster in hot water
Will powdered sugar dissolve more rapidly in cold water or hot water?
Powdered sugar will dissolve more rapidly in hot water than in cold water. The increased temperature of the water enhances the kinetic energy of the molecules, allowing the sugar particles to break apart and dissolve more quickly. In contrast, cold water molecules have less energy, leading to slower dissolution.
What shows that there is an endothermic reaction when you dissolve ammonium in water?
Heat energy is taken IN.
What happens when starch dissolves in water?
Starch cannot dissolve in cold water, however boiling water has sufficient enough energy to dissolve starch.
Why do dissolving tablets dissolve slower in room temp water and lasts longer?
Dissolving tablets dissolve slower in room temperature water because the rate of dissolution is dependent on temperature. As the water gets warmer, its molecules move more quickly and can break down the tablet more effectively. The slower dissolution in room temperature water can result in longer-lasting effects as the active ingredients are released more gradually into the body.
Why do sugar dissolve faster then salt in water?
For dissolving any solute the solvation energy of the solvent has to be more than the lattige energy of the solute. In this case the lattice energy of Nacl[salt] is more than that of sugar. Hence it takes more time to dissolve in water. ---- Akashraj Ghosh.
How do hot water dissolve stain faster than cold water?
Bonds need to be broken for the stain causing material, to dissolve in the water. hot water has additional energy which it transfers into the bonds, therefore loosening the stain more rapidly.
How much heat is released when 200 grams of sodium hydroxide dissolve in water?
When 200 grams of sodium hydroxide dissolves in water, approximately 42 kJ of heat is released. This process is exothermic, meaning it releases heat energy as the ionic compound dissolves.
Why salt dissolves best in hot water?
Heat has more energy, so salt dissolve faster in hot water, because there is more heat and more energy.
How long does it take for a sugar cube to dissolve in one half cup of hot water or and in one half cup of cold water?
The sugar cube in the hot water will dissolve faster because there are more and higher energy collisions between the water molecules and the sugar molecules which will cause the sugar to dissolve faster.
