How is dinitrogen (1) oxide distinguished shed from oxygen​
grigory [225]

Answer:

See Explanation

Explanation:

Both oxygen and dinitrogen (1) oxide are known to rekindle a glowing splint. However, oxygen is an odorless gas while dinitrogen (1) oxide has a faint smell and has an effect on the central nervous system.

Also, the combustion of dinitrogen (1) oxide produces brown fumes of nitrogen IV oxide.

Finally, when dinitrogen (1) oxide and oxgen are both heated with copper, residual nitrogen gas is left with dinitrogen (1) oxide while no residual gas is left with oxygen.

Thank you for posting your question here at brainly. 

E = mc^2 
<span>where E is the energy in joules, </span>
<span>m is the mass in kilograms, </span>
<span>and c is the speed of light. </span>

<span>E = mc^2 </span>
<span>E = (5.63 x 10^-7 kg)(3 x 10^8 m/s)^2 </span>

cluponka [151]

Answer:

5s

Explanation:

The atomic sublevel with the next highest energy after the 4p is 5s.

Based on Aufbau's principle; the sublevels with lower energies are filled up before those with higher energies.

Sublevels do not fill up based on numerical order. The pattern of filling is shown as:

          1s 2s 2p 3s 3p 4s 3d 4p 5s 4d 5p 6s 4f 5d 6p
