Which of the following solution will have the highest freezing point and which will have the lowest freezing point and why ? (i) 0.1 M NaCl solution (ii) 0.1 M glucose solution (iii) 0.1 M `BaCl_(2)` solution
The 0.1 M `BaCl_(2)` solution will have the lowest freezing point, followed by the 0.1 M NaCl and then glucose solutions will have the highest freezing points.
Why is the order of the freezing points?The magnitude of the freezing point is directly proportional to the concentration of solute particles present in a solution. Consequently, the solution with the highest concentration of solute particles will have the greatest depression in its freezing point, and the solution with the lowest concentration of solute particles will have the least depression in its freezing point.
Based on this information, we can determine the relative freezing points of the solutions given as follows:
(i) 0.1 M NaCl solution: The concentration of solute particles in this solution is moderate, so the depression in the freezing point of the solvent (water) will also be moderate.
(ii) 0.1 M glucose solution: The concentration of solute particles in this solution is also moderate, so the depression in the freezing point of the solvent (water) will also be moderate.
(iii) 0.1 M `BaCl_(2)` solution: The concentration of solute particles in this solution is relatively high, so the depression in the freezing point of the solvent (water) will be relatively large.
Therefore, the 0.1 M `BaCl_(2)` solution will have the lowest freezing point, followed by the 0.1 M NaCl and glucose solutions, which will have similar freezing points.

Francium is an alkali metal with atomic number 87 is present in seventh period.
As we go down the group, the number of shells are added and the gap between nucleus and electrons in valence shell increases.
which means the electron in outer most shell, experiences more shielding.
Or we can say that electron in outer most shell experiences less attraction to the nucleus.
This means, the outer most valence electron is easy to remove in case of Francium than any other elements of group 1.
Also, Francium has the lowest electronegativity and with largest atomic radius.
So removal of its valence electron is easy making Francium as the most reactive metal.

why this equation is an example of the Law of Conservation of Mass.
N2 + 3H2 -> 2NH3
Answer:
The equation you provided is an example of a chemical reaction in which nitrogen gas (N2) and hydrogen gas (H2) react to form ammonia (NH3). The Law of Conservation of Mass states that matter cannot be created or destroyed, only transformed from one form to another.
In this reaction, the total number of atoms on the reactant side (left side of the arrow) is equal to the total number of atoms on the product side (right side of the arrow). Specifically, there are 2 nitrogen atoms, 6 hydrogen atoms, and 2 ammonia molecules on the reactant side, and these atoms are rearranged to form 2 nitrogen atoms, 6 hydrogen atoms, and 2 ammonia molecules on the product side.
This demonstrates that the total mass of the reactants is equal to the total mass of the products, which is a key principle of the Law of Conservation of Mass. This law is a fundamental concept in chemistry that helps us understand how chemical reactions take place and how atoms are transformed from one form to another.

The pH of the buffer solution is found to be 0.22.
The balance chemical equation of the reaction is,
HC2H3O2 + NaHCO3 = NaC2H3O2 + CO2 + H2O.
From the above reaction it is clear that one mole of HC2H3O2 is reacting with one mole of NaHCO3 completely.
We know the moles of a solution are given by,
Moles = molariy x volume
Because the volume of HC2H3O2 and NaHCO3 are equal.
We can write,
Final moles = (0.8M-0.2M)V
Final moles = 0.6M.
Now at the end of the reaction 0.6 M concentration HC2H3O2 is remaining.
So the pH of this buffer solution will be given by,

At 46⁰C and 0.880 atm pressure, a gas occupies a volume of 0.600l, It will occupy 1.643 L at 0°C and 0.205 atm.
What is ideal gas equation?PV = nRT is the equation for an ideal gas. P is the ideal gas's pressure, V is the ideal gas's volume, n is the entire amount of ideal gas, expressed in moles, R is the universal gas constant, and T is the temperature.
Given that,
Pressure (P₁) = 0.88 atm
Volume (V₁) = 0.6 L
Temperature (T₁) = 46⁰C = 319 K
Pressure (P₂) = 0.205 atm
Volume (V₂) = ?
Temperature (T₂) = 0⁰C = 273 K
Using ideal gas equation:
P₁V₁/T₁ = P₂V₂/T₂
or, (0.88) × (0.6) / 319 = (0.275 × V₂) /273
or, V₂ = 1.643 L
Thus, it will occupy 1.643 L at 0°C and 0.205 atm.

eugenol acetate + KMnO4-->
eugenol + Br2 -->
eugenol + FeCl3 -->
eugenol acetate --> FeCl3
FeCl3 is produced when eugenol acetate and KMnO4 are combined.
What distinguishes eugenol from eugenol acetate?Eugenol comprises two oxygen atoms, a bulky structure, and can react with an ester to produce eugenyl acetate. In comparison to eugenol, eugenyl acetate has a larger structure and more oxygen, which optimizes the process of fuel combustion.
The usage of eugenol by dentists: why?Eugenol has been used extensively in dentistry to alleviate pulpitis and toothaches (7). Eugenol may be a perfect natural ingredient for use in dental care products, according to a prior study. Eugenol prevents S. from growing and from producing both soluble and insoluble glucans.
