Answer:
Cl₂(g) + 2 KBr(aq) ⇒ Br₂(l) + 2 KCl(aq)
Explanation:
Let's consider the unbalanced single displacement reaction between chlorine and potassium bromide.
Cl₂(g) + KBr(aq) ⇒ Br₂(l) + KCl(aq)
We will start balancing Cl atoms by multiplying KCl by 2.
Cl₂(g) + KBr(aq) ⇒ Br₂(l) + 2 KCl(aq)
Finally, to get the balanced equation, we have to multiply KBr by 2.
Cl₂(g) + 2 KBr(aq) ⇒ Br₂(l) + 2 KCl(aq)
Answer:
6
Explanation:
FCC is face centered cubic lattice. In FCC structure, there are eight atoms at the eight corner of the cubic unit cell and one atom centered in each of the faces. FCC unit cells consist of four atoms, (8/8) at the corners and (6/2) in the faces.
Given that, Cu has FCC structure and it contains a vacancy at origin (0, 0, 0). And there is no other vacancy directly adjacent to the vacancy at the origin. So, all the adjacent positions contain Cu atoms. Hence, the total number of adjacent atoms of the vacancy at origin can jump into this vacancy.
the above FCC unit cell clearly indicates that there are six adjacent atoms adjacent to the vacancy at origin
So, the total number of adjacent atoms of the vacancy at origin can jump into this vacancy is 6.

I don't know what model you're referring to so I can't answer the question. However, upon researching, I found a similar problem. I posted it as an attached picture. Looking at the model, the amount of grams a herbivore eat each day corresponds to the arrow pointing inwards. Since the label says 4.0 g,
<em>the answer is 4 g per day</em>.
