kondaur [170]

Answer:

0.027 moles of carbon dioxide produced by the reaction of 0.085 mol of oxygen.

Explanation:

2C_8H_{18}+50O_2\rightarrow 16CO_2+18H_2O

Moles of oxygen gas = 0.085 mol

According to reaction, 50 moles of oxygen gives 16 moles of carbon dioxide gas, then 0.085 moles of oxygen gas will give:

\frac{16}{50}\times 0.085 mol=0.0272 mol\approx 0.027 mol of carbon dioxide

0.027 moles of carbon dioxide produced by the reaction of 0.085 mol of oxygen.

What volume will 50.2 grams of co2 (g) occupy at stp?
Genrish500 [490]
Number of moles of CO2 =
Mass /Ar
= 50.2 / (12 + 32)
1.14 mols

For every 1 mol of gas, there will be
24000 cm^3 of gas

Vol. = 1.14 x 24 dm^3
= 27.36 dm^3

What is the molar mass of just the O in CO2?
Vlad1618 [11]

Answer:

16 g/mol

Explanation:

In CO2, it means we have 1 mole of carbon and 2 moles of oxygen.

However, we want to find the molar mass of just a single mole of oxygen.

Now, from tables of values of elements in electronic configuration, the molar mass of oxygen is usually approximately 16 g/mol.

In essence the molar mass is simply the atomic mass in g/mol

Which of the following intermolecular forces would affect boiling point the most?
Alekssandra [29.7K]
Hydrogen Bonding will effect the boiling point the most. Let's take an example Butane a four carbon unsaturated organic compound with molecular formula C₄H₁₀ and boiling point -1 °C.

                                                H₃C-CH₂-CH₂-CH₃

Now, replace one hydrogen on terminal carbon with -OH group and convert it into Butanol.

                                                H₃C-CH₂-CH₂-CH₂-OH

The Boiling point of Butanol is 117.7 °C. This increase in boiling point is due to formation of hydrogen bondings between the molecules of Butanol.
