Explanation: It includes the nose, mouth, throat, voice box, windpipe, and lungs. Air enters the respiratory system through the nose or the mouth.
Answer:
I would say you would check for temperature change. A chemical reaction is shown by a change in color, a change in temperature, solids forming, odor, or smoke. So check temperature.
edit: while odor is an option in the answer. i think temp is a better choice.
The balanced chemical reaction is:
C3H8 + 5O2 = 3CO2 + 4H2O
We are given the amount of C3H8 to be used for the reaction. This will be the starting point for the calculations.
73.7 g C3H8 (1 mol C3H8 / 44.11 g C3H8) ( 5 mol O2 / 1 mol C3H8 ) ( 32 g O2 / 1 mol O2 ) = 267.3 g O2
1 mole of CH4 results to 2 moles of H2O.
If 8.5 liters are to be produced, then (1CH4/2H20)*(8.5L h2o) = 4.25L CH4
It will be Solvent the term that would describe the alcohol will be solvent.
