Question

Combination: K(s)+Br2(l)⟶Express your answer as a chemical equation

Answer 1

Step-by-step explanation:

The reaction between potassium (K) and bromine (Br2) produces potassium bromide (KBr).

K + Br2 --> KBr

Now we need to balance the equation. For this, we need to equate the atoms of each element on both sides of the equation.

So in the reactants side:

K - 1

Br - 2

Products side:

K - 1

Br - 1

Let's multiply KBr by 2:

K(s) + Br2 → 2KBr(s)

Now we need to balance K:

2K(s) + Br2 → 2KBr(s)

Let's count again:

Reactants side:

K - 2

Br - 2

Product side:

K - 2

Br - 2

2K(S) + Br2 → 2KBr(S)

Answer: 2K(s) + Br2 → 2KBr(s)
