A I think that a bar graph would best represent this information.
Hmm...since soap is alkaline and tomato juice is acidic (the internet says the pH is 4.smth so yea) so the mixture would be neutral. Thus, the litmus paper would be purple
Answer:
Volume O₂ at STP = 50.4 Liters
Explanation:
4Al(s) + 3O₂(g) => 2Al₂O₃(s) at STP conditions
81g Al(s) = 81g/27g/mole = 3mole Al
moles O₂ consumed = 4/3(3)moles O₂ = 2.25 moles O₂ consumed
Volume O₂ at STP = 2.25moles x 22.4L/mole = 50.4 Liters O₂
