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

What factor is most responsible for the fact that water is a liquid rather than a gas at room temperature?
ivann1987 [24]
The factor that is most responsible for the fact that water is a liquid rather than gas at room temperature is the hydrogen bonding. The hydrogen bonding keeps the water molecules bonded together, otherwise it would have been in a gaseous state. I hope the answer helps you.

A gaseous hydrogen and carbon containing compound is decomposed and formed to contain 82.66% carbon and 17.34% hydrogen by mass.
Romashka [77]

Explanation:

Mole percentage of carbon = \frac{percentage given}{molar mass of carbon}

                                              = \frac{82.66}{12}

                                              = 6.89

Mole percentage of hydrogen = \frac{percentage given}{molar mass of hydrogen}

                                               = \frac{17.34}{1}

                                               = 17.34

Now, dividing mole percentage of both the atoms by 6.89.

Then,     C = 1 and H = \frac{17.34}{6.89} = 2.5

Hence, empirical formula is C_{2}H_{5}.

As, it is given that P = 556 mm Hg. Convert mm Hg into atm as follows.

                        \frac{556 mm Hg \times atm}{760 mm Hg}

                             = 0.7316 atm

Volume is given as 158 mL. So, in liter volume is \frac{158}{1000} equals 0.158 L.

According to ideal gas equation, PV = nRT

                      0.7316 atm \times 0.158 L = \frac{mass}{molar mass} \times 0.082 atm L/mol K \times 298 K          

                       0.7316 atm \times 0.158 L = \frac{0.275 g}{molar mass} \times 0.082 atm L/mol K \times 298 K        

                   molar mass = 58.2 g

Hence, molecular weight of C_{2}H_{5} is 12 \times 2 + 5 = 29.

Therefore, (C_{2}H_{5})_{n} = 58

                               29 × n = 58

                                   n = 2

Thus, molecular formula of the compound is C_{4}H_{10}.
