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)
Its a heterogeneous mixture
The parts are not uniformly mixed

Answer:
Skeletal system
Explanation:
The skeletal system is made up of all the bones, cartilage, and ligaments in the body. There are over 200 bones in the human skeleton, connected by joints which allow them to bend and rotate.
It protects the vital organs, gives our body form and structure, and allows us to move (or bust a move!)
To move, the skeletal system works with the muscles and nerves in the body.
