Question

TF 29 0. 12. 150 pm Cotton Ball with Cotton Ball with Volatile Base Aqueous HX The experimental apparatus represented above is used to demonstrate the rates at which gases diffuse. When the cotton balls are placed in the ends of a tube at the same time, the gases diffuse from each end and meet somewhere in between. where they react to form a white solid. Which of the following combinations will produce a solid closest to the center of the tube? The fig luori H ato best a HCI ICH 3 Nttd → (A) HCI and CH,NH2 (B) HCI and NH (C (HBr and CH3NH2 (D) HBr and NH3 HH 13. 2N205(g) → 4 NO2(g) + O2(g) . A sample of N205 was placed in an evacuated container, and the reaction represented above occurred. The value of P,0s, the partial pressure of N20,(g), was measured during the reaction and

Can you please answer question 10 and explain why the answer is correct?

Thank you! :)

Answer 1

Out of the 4 options provided, only Ammonia (NH3) and hydrochloric acid (HCl) or hydrobromic acid (HBr) react to form a white colored solid product, Ammonium chloride (NH4Cl) or Ammonium bromide (NH4Br) respectively. Hence, option B and D are correct.
