If I’m right this should be the answer
Metals on the left side, metalloids on the staircase, nonmetals on right side
Evaporation of the solution
I can't see the picture, but in general, I believe it is in dropping from the first energy level above the ground state, to the ground state.
Answer:
2.13g
Explanation:
Atomic mass of CO2 = 12 + 32 = 44g/Mol
Atomic mass of C3H8 = 36 + 8 = 44g/Mol
Reaction
C3H8 + 5O2 --> 3CO2 + 4H2O
3CO2 = 6.39g
Required C3H8 = (6.39/(44 x 3)) x 44 = 2.13g
