First you must write a balanced chemical equation.
C3H8 + 5O2 --> 3CO2 + 4H2O
From there, we can set up the stoichiometry equation to solve.
g O2= 70.2 g C3H8 X (1 mol C3H8/44.0962g C3H8) X (5 mol O2/1 mol C3H8) X (31.998g O2/1 mol O2)
Now solve, and you should get 254.7 g O2. Hope this helped!
Answer:The electromagnetic spectrum includes, from longest wavelength to shortest: radio waves, microwaves, infrared, optical, ultraviolet, X-rays, and gamma-rays.
Explanation:
Lithium is a metal and Fluorine is a non-metal, which means they will form an ionic bond. An ionic bond is when a metal atom donates its electron complete to a non-metal atom.
A physical change. chemical changes require the molecule itself to change. If you put NaCl into solution, the NaCl is still there which is evident by the fact that if you lower the amount of water, NaCl precipitates out.
