The freezing point of a 1 m solution of FeCl is expected to be lower than that of a 1 m solution of glucose and this is because FeCL contains mole particles which means more solute particles than glucose.
Why is 1M Fecl3 have lower freezing point than 1M glucose solution?Dissolving something in water lowers its freezing point. This freezing point depression depends on the number of solute particles or solute ions or solute molecules present in the solution.This is because FeCL₃ can dissociate into cations and anions in aqueous solution. Therefore, aqueous solutions of 1 M FeCL₃ contain more dissolved particles compared to 1 M glucose solutions. Note that glucose cannot dissociate into ions in water. Therefore, their freezing points are higher.What is freezing point?Freezing is the phase change of a substance from liquid to solid.This is a phase change phenomenon, meaning that a substance changes from one cohesive state to another. The freezing point is the temperature at which a liquid changes physical state from liquid to solid at atmospheric pressure.These two phases are at the freezing point.

what is the molar mass of a substance if a total charge of 4934.5 c deposited 5.47 g of the substance on an electrode through a reaction involving 2 electrons?
To find the molar mass of a substance from the given information, you need to first determine the number of moles of the substance that was deposited on the electrode.
The charge on an electron is about -1.60 x 10^-19 coulombs, so the total charge of 4934.5 c deposited on the electrode corresponds to about 3092.19 moles of electrons. Since the reaction involves two electrons per mole of the substance, the number of moles of the substance deposited on the electrode is about 1546.1.
The molar mass of a substance is the mass of one mole of the substance, so to find the molar mass of the substance in this case, you need to divide the mass of the substance deposited on the electrode (5.47 g) by the number of moles of the substance (1546.1):
Molar mass = (5.47 g) / (1546.1 mol) = about 0.00356 g/mol
The unit for molar mass is usually grams per mole (g/mol), so the molar mass of the substance in this case is about 0.00356 g/mol.

The nuclear equation of the beta decay of 39/17 Cl is as follows:
39/17 Cl → 39/18 Cl + 0/-1 e
What is nuclear reaction?A nuclear reaction is a process such as the fission of an atomic nucleus, or the fusion of one or more atomic nuclei and/or subatomic particles in which the number of protons and/or neutrons in a nucleus changes.
The reaction products may contain a different element or a different isotope of the same element due to this change.
A beta decay is a nuclear reaction in which a beta particle (electron or positron) is emitted. A beta particle is an energetic electron or positron produced as the result of a nuclear reaction or nuclear decay. A beta decay occurs as depicted below;
A/Z X → A/(Z + 1) X‘ + e
Where;
A and Z are the mass number and atomic number of the decaying nucleusX and X′ are the initial and final elements, respectivelyTherefore, if a 39/17 Cl undergoes beta decay, the nuclear reaction can be given as follows:
39/17 Cl → 39/18 Cl + 0/-1 e

Thirty grams of lead oxide and fifteen grams of ammonia react completely to produce solid lead, nitrogen gas, and liquid water. What will be approximate mass of all three products?.
The stated assertion is that the combined mass of the three goods is about 45 g.
What is the purpose of nitrogen?The chemical industry depends on nitrogen. It is used to create explosives, nylon, nitric acid, fertilizers, and colors. Nitrogen must initially be combined with hydrogen to create ammonia in order to create these products. The Haber process is used for this.
Is nitrogen bad for people?People lose their lives every year by inhaling "air" with insufficient oxygen. Many people believe nitrogen gas is safe since it makes up 78 percent of something like the air we breathe. Only when nitrogen is combined with the right amount of oxygen is it safe to breathe, though.
