Answer:

Increasing temperature increases the solubility of most salts, but not all. The reason for the differences is that dissolution involves three steps: breaking bonds of salt in the lattice; forming cavities in water the same size as the ions; interacting the salt with water in the cavity.

What is an ionic compound? Write an example.
Flura [38]
An ionic compound is a compound between a metal and a non metal where the metal (normally from group 1 or 2) transferrs an electron to the non metal ( most commonly from group 6 or 7) . this is so that both atoms have a full outer shell of electrons. the metal gains a positive charge and the non metal a negative charge. they are held together by electrostatic forces of attraction. an example would be sodium chloride (salt) sodium is in group 1 and chlorine in group 7 so sodium transfers one electron :)

Mkey [24]

D. It is a chemical change because solubility in water of Solid A is different than the solubility in water or both Potassium Iodide and Silver Nitrate

Explanation:

From the given table which summarizes findings about the experiment, we can conclude that It is a chemical change because solubility in water of Solid A is different than the solubility in water of both Potassium Iodide and Silver Nitrate.

  • A chemical change is a form of change in which new substances are produced.
  • A physical change is one in which the states of matter changes especially the form.

Now we that two soluble substances goes to insoluble product.

  • A substance is soluble when they go into solution with a solvent of the same type.
  • This change from solubility to insolubility of a compound is a typical chemical change.
  • Other forms of changes are just physical changes.
