Answer:
red and 4.6×10^-40
Explanation:
The energy of a foton is calculated by thefollowing formula: Efoton=h×(c/lapda). Fill in 7.0×10^-7 gives us Efoton=6.626×10^-34 (planck constant) × 7.0×10^-7=4.6×10^-40.
Answer:
A. 20 Hz
Explanation:
24 divided by 1.2 = 20 Hz
Answer:
3.65 g of cyclohexene
Explanation:
Cyclohexanol + phosphoric acid ----> cyclohexene
The reaction is 1:1 hence the limiting reactant is phosphoric acid.
Hence,
1 mole of phosphoric acid yields 1 mole of cyclohexene
0.0444 moles of phosphoric acid yields 0.0444 moles of cyclohexene
Theoretical yield = number of moles of cyclohexene × molar mass of cyclohexene
Theoretical yield = 0.0444 moles of cyclohexene × 82.143 g/mol
Theoretical yield = 3.65 g of cyclohexene
Answer: 680ml
Explanation: (450grams)*(0.665g/ml) = 677 ml
