What conclusions can you draw about the factors that affect the rate of solution formation?
konstantin123 [22]

The factors that affect the rate of solution formation are capable of either increasing the rate of solution formation or decreasing it.

<h3>Factors that affect the rate of solution formation</h3>

The rate of solution formation from a chemical reaction depends on the following factors:

  • Quantity of solute and solvent: The solute should be in less quantity and solvent should be more in quantity to dissolve the solute. This will enhance the formation of solution

  • The size of the solute particles: When the solute particles are in smaller sizes, they react faster with the solvent to form solutions.

  • The temperature of solvent: In increased temperature, the solute reacts faster with the solvent.

Therefore, the factors that affect the rate of solution formation are capable of either increasing the rate of solution formation or decreasing it.

Why are the coefficients before a chemical symbol important?​F. ​ They show the number of elements in each molecule.​G. ​ They i
Valentin [98]

Answer:They indicate the number of molecules of each substance

Explanation:

When we write chemical reaction equations, we usually put a number before the symbol of each reactant.

These coefficient shows the number of molecules of that specie that is involved in the balanced reaction equation for the reaction.

These coefficients are important because they are used in carrying out stoichiometric calculations.

What are the benefits of a model to demonstrate the atomic theory?
Norma-Jean [14]

Answer:

Atomic models are important because, they help us visualize the interior of atoms and molecules, and thereby predicting properties of matter.

Explanation:

We study the various atomic models in our course of study because, it is important for us to know, how did people come to the present concept of an atom. How did physics evolve from classical to quantum physics.

All these are important for us to know and thus, knowledge about various atomic models, their discoveries and drawbacks and finally improvements based on scientific evidence present at that time is important for us to understand the underlying theory very well.
