1.Compare and contrast the rate of solution formation between the three physical forms of salt that were placed in the vial and not agitated with the three forms of salt that were placed in the vial and were agitated.2. On the basis of your results, what is the relationship between the temperature of the solvent and the rate of solution formation?
3. Use your knowledge of collision theory to explain the results of your experiments in this laboratory.
Answers
Thestable form of salt at standard temperature and pressure is solid. If you addwater to salt, it will dissolve. However, there are certain factors that affectthe rate of solution formation of salt. The rate of formation of salt solutionis faster when the vial is agitated than when it is not agitated. By agitatingthe solution, you are increasing the surface area of the salt particles incontact with water.
Answer:
answer for number 2
Explanation:
By increasing the temperature of the solvent, the movement of molecules sped up resulting in the more movement of particles and they bump into each other more vigorously. As a result of that, the particles of the solute break faster and dissolve in the solvent faster .

1) The Universal gravitaional law, stated by Sir. Isaac Newton, states that the force of gravitational attraction between two objects is directly proportional to the product of their masses and inverse to the square of the distance that separates their centers.
2) Mathematically, it was expressed in this form:
F = G × m₁ × m₂ / d².
where G is the proportinality constant, m₁ and m₂ and the masses of the objects, and d is the distance that separates the centers of the two objects.
3) Then, the answer is that the greatest for of gravitaional attraction is:
- that of the two objects for which the product of the masses is the greates (assumin same distance between them), or
- that of the two objects that are closer (assuming the product of the masses is the same).
Those requirements are met perfectly by a black hole.

Answer : The moles ratio between the nitrogen gas and hydrogen gas are, 1 : 3 respectively.
Explanation :
The balanced chemical reaction will be,
Mole ratio : It is defined as the ratio of the number of moles of the substances whose ratio is to be calculated.
In a chemical reaction, the stoichiometric coefficients represents the number of moles.
By stoichiometry of the reaction we can say that,
1 mole of nitrogen gas reacts with 3 moles of hydrogen gas to produce 2 moles of ammonia gas.
Hence, the mole ratio of between the nitrogen gas and hydrogen gas are, 1 : 3 respectively.
For instance you have a chemical reaction of N2 + 3H2 -> 2NH3. The number of moles of N2 is 1, H2 is 3 and NH3 is 2. The mole to mole ratio between nitrogen gas and hydrogen gas is 1/3 or 1 is to 3.
