Use the data table below. What are the two gases present in the test tube If the glowing splint ignites and the burning splint creates a small explosion? How do you know?

oxygen and hydrogen

Explanation:

oxygen gas ignites a glowing splint because it supports burning. hydrogen gas extinguishes the burning splint with a pop sound hence the small explosion

b) mutualism

hope this : )

answer: the value of enthalpy change will be -152.80 kj.

solution:

pressure = 1atm , temperature = = 298 k

given that pressure and temperature are same in both gases , the number of moles of both gases can be determined by the ideal gas equation.

according to reaction 3 moles no are reacting with 1 mol of ,then 0.49 mol of no will react with moles of ozone that is 0.16 moles of ozone. since, no is limiting reagent and is an excessive reagent.

enthalpy change for the reaction between the given volumes of the gases is :
