How many moles of nitrogen gas are there in 6.8 liters at room temperature and pressure (293 K and 100 kPa)?

Chemistry

7 0
To solve this question, we will simply use the gas law which is as follows:

PV = nRT where:
P is the pressure = 100 kPa = 0.986923 atm
V is the volume = 6.8 liters
n is the required number of moles
R is the gas constant = 0.08206
T is the temperature = 25 degree celcius (room temp) = <span>298 kelvin

Substitute in the above equation to get the number of moles as follows:
</span> 0.986923 x 6.8 = n x 0.08206 x 298
n = 0.2744 moles

A product of homolytic fission can never be
algol13

Answer:

both

Explanation:

A homolytic fission is said to have occurred when the breakage of a bond between two atoms leaves each of the bonding atoms with equal number of electrons. Homolytic fission often results in the creation of radicals.

Since homolytic fission yields two species with equal number of electrons(usually odd number of electrons), the products of such process can not be charged. They can not be nucleophiles because nucleophiles need to possess two electrons which can be shared with another chemical specie.

The chemical equation below shows the formation of aluminum oxide (Al2O3) from aluminum (Al) and oxygen (O2).
Rufina [12.5K]

Answer:

Mass = 182.4 g

Explanation:

Given data:

Number of moles of Al₂O₃ = 3.80 mol

Mass of oxygen required = ?

Solution:

Chemical equation:

4Al + 3O₂    →       2Al₂O₃

Now we will compare the moles of aluminum oxide and oxygen.

                Al₂O₃           :           O₂

                   2               :            3

                 3.80            :         3/2×3.80 = 5.7

Mass of oxygen:

Mass = number of moles × molar mass

Mass = 5.7 mol × 32 g/mol

Mass = 182.4 g
