Which of the following is the test for oxygen has? a. a glowing wooden splint is placed in the gas b. a lit wooden splint is placed in the gas c. the gas is bubbles into limewater d. damp blue litmus is placed in the gas

A or B depends on what you mean by lit or glowing but when you place a wooden split in the sample the gas must reignite but there can be some confusion between hydrogen and oxygen mainly because a splint can cause a slight popping sound while it reignites but hydrogen pops are more violent and can most time extinguish the splint.
