Answer:
heat energy are absorbed by water molecules and it is used to change the molecules from liquid to gas? if thats what your asking.
Explanation:
They all have densities greater than the density of the fluid in which they are<span>sinking. The mass of the displaced liquid is less than the mass of the sinking body.</span>
Answer:
They dissociate into positive and negative ions in the solution.
Explanation:
NaCl when dissolved in water dissociates into Na+ ion and Cl- ion.
3 - Effective collisions between reacting particles
For a chemical reaction to occur, reacting particles must collide - however, not all collisions result in a reaction. They must have enough energy in the collision to react (that is, be above the activation energy). The rate of reaction is determined by the rate of successful collisions, that is to say, the more successful collisions there are in a unit time, the faster the reaction rate.
