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)3

Moreover, 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

The compound dioxane, which is used as a solvent in various industrial processes is composed of C,H, and O atoms. Combustion of

Lady_Fox [76]

Answer:

The correct formula of dioxane is C₄H₈O₂.

Explanation:

Given data:

mass of dioxane= 2.23 g

mass of water = 1.802 g

mass of carbon dioxide = 4.401 g

molar mass of dioxane = 88.1 g / mol

Molecular formula of dioxane = ?

Solution:

percentage of carbon = (4.401 g/2.23 g ) × (12 /44) × 100

= (1.98 × 0.273) × 100 = 54.1

percentage of hydrogen = (1.802 g/ 2.23 g) × (2.016 /18.016) × 100

= (0.81 × 0.112) × 100 = 9.072

percentage of oxygen = 100 - (54.1 + 9.072)

= 100 - 63.172 = 36.828

Now we will determine the number of grams atoms of carbon, hydrogen and oxygen.

No. of gram atoms of carbon = 54.1 /12 = 4.51

No. of gram atoms of hydrogen = 9.072 / 1.008 = 9

No. of gram atoms of oxygen = 36.828 / 16 = 2.302

Atomic ratio:

C :H :O 4.51/ 2.302 : 9 / 2.302 : 2.302 /2.302

C :H :O 2 : 4 : 1

Molecular formula:

Molecular formula = n × (empirical formula)

n = molar mass of compound / empirical formula mass

empirical formula mass= 2 × 12 + 4 × 1.008 + 1 × 16

empirical formula mass= 24+ 4.032 +16 = 44.032

n = 88.1 / 44.032 = 2

Molecular formula = n × (empirical formula)

Molecular formula = 2 × (C₂H₄O)

Molecular formula = C₄H₈O₂

Why do substances with weak intermolecular forces form solids at low melting points?

Advocard [28]

To make any substance solid, molecules must come very close to each other. Substances with weak intermolecular forces have weak bonding. Hence to make their molecules come close to each other, we must provide low temperature.

What is 25 m rounded to one significant figure

den301095 [7]

Rounded to 1 significant figure, 25 m would go to 30. This is because 0 isn't significant, so the 3 is the only significant figure.
