Questions and Answers

What is a characteristic property of nitrogen gas?

  • Extinguishes a glowing splint (correct)
  • Affects lime water and hydrogencarbonate indicator
  • Reignites a glowing splint
  • Supports combustion

    • How is nitrogen's presence often inferred?

  • By its effects on lime water and hydrogencarbonate indicator
  • By the absence of other gases (correct)
  • By its ability to support combustion
  • By its inability to reignite a glowing splint

    • What effect does air have on a burning splint?

  • Produces a small explosion
  • Extinguishes the flame
  • Sustains the flame due to oxygen (correct)
  • Causes the splint to reignite
