Answer:
no it is dry_____________
Answer:
e. 4.847 x 10-19 J
Explanation:
From the given information:
The equation connecting the photon energy and the wavelength is:

where;
= 6.626 * 10 ^{-34} J.s
= 3.00 * 10^8 m/s
wavelength 

To determine the photon energy of violet light

= 4.847 × 10⁻¹⁹ J
If drinking coffee makes you shorter, than you should try to limit your coffee intake.
Answer: The amount of heat needed is = 4.3kJ
Explanation:
Amount of heat H = M × C × ΔT
M= mass of benzene = 64.7g
C= specific heat capacity = 1.74J/gK
ΔT = T2-T1
Where T1 is initai temperature = 41.9C
T2 is the final temperature( boiling point of benzene) = 80.1C
H= 64.7×1.74×80.7
H= 4300J
H=4.3kJ
Therefore, the amount of heat needed is 4.3kJ
