What mass of oxygen forms from 71.89 g CO2?

liubo4ka [24]

Answer:

52.28g

Explanation:

Given:

Mass of CO₂ = 71.89g

Solution:

The equation of the reaction:

CO₂ → C + O₂

We want to determine the mass of O₂ that will form from this reaction.

To do this, find the number of moles of CO₂:

Number of moles of CO₂ = $\frac{mass}{molar mass}$

Molar mass of CO₂ = 12+ 2(16) = 44g/mol

Number of moles of CO₂ = $\frac{71.89}{44}$ = 1.63mole

From the equation of the reaction:

1mole of CO₂ will produce 1 mole of O₂

So 1.63 mole of CO₂ also produces 1.63mole of O₂

The mass of O₂:

Mass of O₂ = number of moles of O₂ x molar mass of O₂

Molar mass of O₂ = 2 x 16 = 32g/mol

Mass of O₂ = 1.63 x 32 = 52.28g

A lower yield of phosphonium salt is obtained in refluxing benzene than in xylene (Experi- ment 43A). Look up the boiling points

77julia77 [94]

Answer:

Benzene has a boiling point of 80.1 ºC, while xylene has a boiling point of 139 ºC, indicating that benzene has a lower temperature than xylene, this means that the reaction will be carried out at a lower temperature.

High temperatures will favor creating products with higher performance since more energy is available. Instead at lower temperatures, the reaction may not continue at the same rate, so the products will form very slowly and will not form completely, resulting in poor yield.
