Using the law of the conservation of mass, the reactions can be shown to obey the law.
What is the law of conservation of mass?We need to know what the law of the conservation of mass says so that we can be able to know how we can be able to apply the law in the proper perspective. We have to know that the law says that total mass of the system would remain constant. The implication of this is that the mass before the reaction would be the same as the mass after the reaction. The mass of the substance must be able to add up in the system that is under study as we have one here.
Mass of the iron = 56 g
Mass of the chlorine = 35.5 g
Balanced reaction equation;
[tex]2Fe + 3Cl_{2} ---- > 2FeCl_{3}[/tex]
This is the formation of the iron III chloride
Total mass on the right hand side = 2(56) + 6(35.5) = 325 g
Total mass on the left hand side = 2[56 + 3(35.5)] = 325 g

An investigation analyzed a sample of black ink to determine its components.Which property allows the components to separate
Because of its simplicity, comparatively low cost, great sensitivity, and rapid separation, TLC is an extensively used analytical method.
Using a thin stationary phase supported by an inert backing, thin layer chromatography (TLC) is a chromatographic technique used to separate the components of a mixture. It can be carried out on an analytical scale to track the development of a reaction or on a preparative scale to purify minute quantities of a chemical. Similar to all chromatography, TLC works on the premise that a chemical will have varying affinities for the mobile and stationary phases, which will influence how quickly it migrates. TLC aims to produce well-defined, well-separated spots.

Why do the fourth and fifth periods contain 18 elements rather than 8 as observed in the second and third periods?
The fourth and fifth periods contain 18 elements rather than 8 as observed in the second and third period because of the accommodation of 10 additional electrons in the 3d orbital.
The number of orbitals that can be accommodated by s subshell is one, p subshell is three, d subshell is five and f subshell is seven.
In the second and the third period, the 2s subshell is filled with two electrons, 2p subshell with six electrons .So, the second period contains eight elements. The sequence in third period is similar to that of second period with additional filling of 3s and 3p subshell.
In the fourth period, electrons are first filled in the 4s subshell, only after that they can be filled in the 3d subshell. So, fourth period contains 18 elements , which is due to the additional 10 electrons in 3d subshell. This is similar in the case of fifth period also.

1.53 × 10⁻⁵ moles of aspartame are present in 4.50 mg of aspartame.
Two amino acids, aspartic acid and phenylalanine, make up the low-calorie sweetener known as aspartame. In addition to being present in tabletop sweetener packets, aspartame is a common component used to substitute sugar in low-calorie foods and beverages.
Here there are 4.50 mg of aspartame.
First, the mass is converted from mg to g by:
1 g = 1000 mg
So, 1 mg = 0.001 g
So, 4.5 mg = 4.5 × 10⁻³ g
Molar mass of aspartame = 294.40 g/mol
So, Number of moles of aspartame = [tex]\frac{Given mass}{Molar mass}[/tex]

If the garbage truck and minivan in Part A get into an accident with each other, how can safety restraints in a car can save a life? Explain your response using one of Newton’s laws.
Which of Newton’s laws of motion act upon the vehicles at the point of impact? Explain your answer
Newton's law of motion that act upon the vehicles at the point of impact is the second law of motion.
Newton's second law of motion states that the force applied to an object is directly proportional to the rate of change of momentum that is produced. Mathematically, we have;
F = m·v - m·u/Δt
Where;
m = The mass of the object
v = The final velocity of the object
u = The initial velocity of the object
Δt = The duration of motion of the object during change in velocity
Therefore, given that the mass, 'M', of the truck is larger than the mass, 'm', of the minivan, where the time of change in velocity Δt, and the initial and final velocities of both automobiles are the same such as in a sudden stop, the garbage ruck will exert more force than the minivan, and therefore, the garbage truck has a greater initial momentum before the automobiles are brought to a stop.

The mass of 1 mole of a chemical is indicated by its molar mass. It provides you with the number of grams per mole of a substance, to put it another way.
ΔT = Kc*W*i
Kc = cryoscopy constant of the solute X
W = molality of the solution
i = van't Hoff factor, For organic molecules, such as alanine, i = 1.
n = 45.8/89.09
n = 0.5141 mol
W = 0.5141/1.2 = 0.4284 mol/kg

W = 0.2354 mol/kg
The number of moles of the solute is then:
W = n/1.2
0.2354 = n/1.2
n = 0.2825 mol
