How many grams of KBr are present in 250.0mL of a 1.20M solution
castortr0y [4]
Molar mass KBr = 119 g/mol

Volume in liters: 250.0mL / 1000 => 0.25 L

n = M x V

n = 1.20 x 0,25 => 0.3 moles of KBr

Therefore:

1 mole KBr ----------- 119 g
0.3 moles KBr -------- ??

0.3 x 119 / 1 => 35.7 g of KBr

Question 19 Write a balanced half-reaction for the oxidation of gaseous nitrogen dioxide to nitrate ion in acidic aqueous soluti
Alexxx [7]

Answer:

This will be the balanced half reaction:

NO₂(g)  + H₂O (l) →  NO₃⁻(aq)  + 1 e⁻  + 2H⁺ (aq)

Explanation:

In acidic medium, the redox balance has to be done as this way.

As it is an oxidation, we know that oxidation state has increased.

NO₂(g)   →  NO₃⁻(aq)  + 1 e⁻

Nitrogen in NO₂ acts with +4; in the nitrate, N acts with +5

The nitrogen has released 1 electron.

As we are in acidic medium, we must complete with water, in the same side, as we have less oxygens and in the opposite side, with protons to balance the H. This will be the balanced half reaction:

NO₂(g)  + H₂O (l) →  NO₃⁻(aq)  + 1 e⁻  + 2H⁺ (aq)
