1. on the basis of your results, what is the relationship between the temperature of the solvent and the rate of solution formation?

As the temperature increases, the rate of formation of solution increases.

Explanation:

Solvent is defined as a substance which is present in larger proportion in a solution. Solute is dissolved in the solvent to form a solution.

As, the temperature of the solvent increases, the kinetic energy of the particles of solvent increases and the intermolecular spacing between the solvent particles increases and therefore, this results in the more dissolution of the solute particles in the solvent and hence, the formation of solution increases.

Therefore, there is a direct relationship between the temperature of the solvent and the formation of the solution.

- "the choice that is not an indicator of a chemical change is "state of matter changes". more common than not, chemical reactions produce energy in the form of light or heat. along with energy, they also produce a new substance called the product that could be in any state of matter (solid, gas, or liquid)."

"among the transition metal elements, manganese and zinc have a slight lowering of electronegativities. the reason behind this is that the nuclear charges of these elements are slightly weaker than the other transition metal elements due to the way their valence electrons are filled up. both manganese and zinc have their valence electrons filled up to the 4th shell with 1 pair of electrons (4s2) completely occupying it. although the electrons in the 3rd shell (3d) are yet to be paired since the outer most shell is filled up, the ability of the nucleus to attract electrons is lessened. hence,   the electronegativity (or the ability to attract electrons) is lessened."
