Answer:
Tin bromine = Snbr2
aluminum fluorate = AlFe3
iron oxide = Fe2o3
potassium chloride = KCL or 2KCL = K2CL2
All Pairs are correct
Answer:A. Increases
Explanation:
Heating or an increase in temperature increases the kinetic energy of particles thereby increasing their motion and how they relate and react with one another.
Increase in the temperature of the solvent is directly proportional to the rate of dissolution. The rate of dissolution increases due to the increase in kinetic energy. This makes the solvent particles interact faster with the solute particles thereby increasing the dissolution rate.
The prefix "poly-" means "many," and "atomic" refers to atoms, so a polyatomic ion is made of 2+ atoms covalently bonded together. These ions are charged, which is why they can never stand alone.
Answer: -
Solubility of a substance depend on the balance of intermolecular forces between the solvent and solute, and the entropy change that accompanies this process.
Temperature and pressure also plays a role in solubility.
A solution having Group 1 cations like lithium, sodium, potassium etc are always soluble.
A solution having NH₄⁺ is soluble.
All salts with anion as nitrates, acetates, chlorates, and perchlorates are soluble in water.
