Each mole of C₂H₄ requires 3 moles of O₂ to react.
5.75 moles of C₂H₄ will require:
3 x 5.75 = 17.25 moles
Each mole of gas occupies 22.4 L at STP.
Liters of gas = 17.25 x 22.4
= 3.86 x 10² L
The answer is C.
Answer:
c
Explanation:
you don't think of particles as dense and less dense
dust particles containvenergy but won't release it unless acted upon a force
gas molecules move freely and collide with dust particles which is correct
