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.
Answer:
there is no limiting reactant.
Explanation:
Given that:
CaF₂ + Br₂ -----> CaBr₂ + F₂
From the above equation;
We can see that there is an equal number of moles in the reactant side of the equation.
i.e.
one mole of CaF₂ reacts with one mole of Br₂.
Thus, there is no limiting reactant.
Hz is the measurement of a frequency equal to one cycle per second. since this wave shows 9 peaks and valleys or "cycles" your answer would be 3 Hz due to the fact that the length of time is 3 seconds. (3 cycles per second X 3 seconds.)

#2 During chemistry lab, Mrs. Black’s students placed an antacid tablet in a zip lock bag. They recorded the mass of the tablet in the bag. Then they carefully added 50 grams of water and quickly sealed the bag. The tablet began to fizz and soon disappeared. The bag was filled with gas and it felt cold to the touch.
