The elements should be label as follows yellow = OH, blue = Fe, green = Ba, red = Cl
The mix between aqueous barium hydroxide and aqueous iron chloride leads to barium chloride and iron hydroxide. This reaction is shown below:
Ba(OH)2 + FeCl3 → BaCl2 + Fe(OH)3Moreover, in these products, the iron hydroxide will form a solid substance that precipitates in the bottom of the container, while the barium chloride is more likely to maintain its liquid state.
According to this, the substance in the bottom is the iron hydroxide or Fe (OH)2, and in this, the yellow dots represent the Hydroxide or OH, while the blue dots are the Iron considering there in iron hydroxide there are two molecules of OH for each molecule of iron.
On the other hand, at the top, there is the barium chloride or BaCl2. This means the green dots are the Barium and the red ones are the Chlorine as there should be more Chlorine particles than Barium ones

Chemical contamination is likely to occur when cleaning products are not stored properly.
Chemical contamination refers to the introduction of harmful chemicals into food, water or the environment. These chemical substances may come in contact with food and water in many ways.
The most common sources of chemical contamination are chemical substances that are not properly stored.
Hence, chemical contamination is likely to occur when cleaning products are not stored properly.

e. Each energy level has a specific energy value
Answers
The model of Neils Bohr postulates that electrons in atoms are found in specific energy levels. Transition from a higher to a lower energy level produces an emission spectrum characteristic of elements.
According to Bohr's model of the atom, an electron in atom exists in distinct energy levels. Electrons can be promoted from lower to higher energy levels when they absorb energy. The electrons are unstable in this higher energy excited state hence they quickly return to the ground state emitting energy. This emission is characteristic of elements.

Explanation:
calculate the boiling point elevation for solution of 25.0 grams of menthol in 130 grams of ethanol. Ethanol boiling point elevation constant is 1.22 oC/m
Answers
Answer:
Explanation:
When a solute is added to a solvent, the vapor pressure of the solvent (above the resulting solution) is less than the vapor pressure above the pure solvent. The boiling point of a solution, then, will be greater than the boiling point of the pure solvent because the solution (which has a lower vapor pressure) will need to be heated to a higher temperature in order for the vapor pressure to become equal to the external pressure (i.e., the boiling point).
The boiling point of the solvent above a solution changes as the concentration of the solute in the solution changes (but it does not depend on the identity of either the solvent or the solute(s) particles (kind, size or charge) in the solution).

¿Qué son las fuerzas intramoleculares?
Answers
Respuesta:
Las fuerzas intermoleculares que actúan entre las moléculas se clasifican en : Dipolos permanentes. Dipolos inducidos. Dipolos dispersos.
Explicación:
Dentro de una molécula, los átomos están unidos mediante fuerzas intramoleculares (enlaces iónicos, metálicos o covalentes, principalmente). Estas son las fuerzas que se deben vencer para que se produzca un cambio químico. Son estas fuerzas, por tanto, las que determinan las propiedades químicas de las sustancias.
Sin embargo existen otras fuerzas intermoleculares que actúan sobre distintas moléculas o iones y que hacen que éstos se atraigan o se repelan. Estas fuerzas son las que determinan las propiedades físicas de las sustancias como, por ejemplo, el estado de agregación, el punto de fusión y de ebullición, la solubilidad, la tensión superficial, la densidad, etc.

Continual eruptions occur along mid-ocean ridges, forming new sea-floor rock. The
rocks closest to a mid-ocean ridge are the youngest | oldest. As you move away from
a mid-ocean ridge, the rocks get younger | older. This implies that crust is being

Answers
The characteristics of the ocean ridges allow finding the results to complete the statements are:
The rocks near the ridge are YOUNGER. While you walk away the rocks are OLDER. This implies that the cortex is PRODUCING in the ridges.
The oceanic ridges are mountain ranges or chains of volcanic mountains at the bottom of the ocean, in these the magma that rises cools and forms young rocks, in they are pushed by the other rocks that emerge, in general they are located on the edges of the tectonic plates .
Therefore, the oceanic ridges are the point where the earth's crust is separating, therefore it has the youngest rocks and in the furthest points it has the oldest.
Let's find the correct words for each phrase to be correct:
The rocks near the ridge are YOUNGER. You walk away the rocks are OLDER. This implies that the cortex is PRODUCING in the ridges.
As a consequence of the characteristics of the ocean ridges, we can find the results to complete the statements are:

If the reaction occurs between Fe₂S₃(s) and HBr(aq) and the equation is properly balanced with the smallest whole-number coefficients, what is the sum of the coefficients for all reactants and products?
Let's consider the unbalanced equation for the reaction between Fe₂S₃(s) and HBr(aq). This is a double displacement reaction.
Fe₂S₃(s) + HBr(aq) ⇒ FeBr₃(aq) + H₂S(g)
We will balance it using the trial and error method.
First, we will balance Fe atoms by multiplying FeBr₃ by 2.
Fe₂S₃(s) + HBr(aq) ⇒ 2 FeBr₃(aq) + H₂S(g)
Then, we will balance S atoms by multiplying H₂S by 3.
Fe₂S₃(s) + HBr(aq) ⇒ 2 FeBr₃(aq) + 3 H₂S(g)
Finally, we will get the balanced equation by multiplying HBr by 6.
Fe₂S₃(s) + 6 HBr(aq) ⇒ 2 FeBr₃(aq) + 3 H₂S(g)
The sum of the coefficients for all reactants and products is:
