Answer: Yes we agree with the student's claim.
Explanation:
When the molecules are present in smaller size, more reactants can react as decreasing the size increases the surface area of the reactants which will enhance the contact of molecules.Hence, more products will form leading to increased rate of reaction.
On increasing the temperature will make more reactant molecules will have sufficient energies to cross the energy barrier and thus the number of effective collisions increases, thus leading to more products and increased rate of reaction.
When the solution is stirred , the molecule's kinetic energy and thus the rate of reaction increases.
Thus smaller size, stirring and increase of temperature will make the solution quickly.
Law of Definite Proportions states that a compound is composed of the same ratio of elements present. The formation of water has a reaction:
H2 + 1/2 O2 = H2O
The limiting reactant would be the element with the least ratio of molar mass to stoichiometric coefficient, and that would be H2, not O2.
Weight has to do with how hard gravity is pulling on it. While mass is do to with the atoms in the matter.
