Explanation:
Potassium cyanide. Almost like salt, looks like sugar.
The picture of Au₃N is attached below.
The first part of the picture shows the formation of Au and N ions.
Formation of Au⁺¹ :
As Gold has one valence electron in 6s¹ therefore, it will loose it to form Au⁺¹. In case of Au₃N three atoms of Au looses three electrons to form three Au⁺¹ ions.
Formation of N⁻³ :
As Nitrogen has 5 valence elctrions therefore, it will gain three electrons that lost by Au to form Nitrite (i.e. N⁻³)
Formation of Au₃N:
Three cations of Au⁺ combines with one anion of N⁻³ to form a neutral ionic compound i.e. Au₃N as shown in second part of the picture.
Your answer would be C. Potential energy is when your withholding the action and are about to carry through with the action
<span>4 NH</span>₃<span> + 5 O2 = 4NO + 6 H</span>₂O
4 moles NH₃ ---------> 5 moles O₂
3.75 mols NH₃ -------> ?
Moles O₂ = 3.75 x 5 / 4
Moles O₂ = 18.75 / 4
= 4.6875 moles of O₂
hope this helps!
