When glucose (C6H12O6) reacts with oxygen, carbon dioxide and water are produced. The reaction produces moles of carbon dioxide and moles of water.
<span> (a) the work done on the gas
From the definition of work in thermodynamics,
W = integral (PdV)
It is said that the process above is done at constant volume. Therefore, the value of dV is zero which would result to
</span>W = integral (PdV) = 0
<span>
(b) the increase in internal energy of the gas
</span> From the first law of thermodynamics,
ΔU = Q + W
where U is the change in internal energy, Q is the heat and W is the work which is zero in this case
ΔU = Q = 209 J<span>
(c) its final temperature
at constant volume,
Q = nCv(T2 - T1)
209 = 1 (3R/2) (T2 - 300)
T = 316.76 K</span>
Answer:
carbohydrates , minerals - lime coal
Answer:
Wc = 7.84 weight of crown
Ww = 7.84 - 6.86 = .98 weight of water displaced
Density = 7.84 / .98 = 8 crown is 8 X that of water
Since gold has a density of 19.3 that of water the crown is certainly not 100 percent (if any) gold
The correct answer to the question above is the third option; ultrasound imaging of the liver. The ultrasound imaging of the liver is definitely not an application of Doppler technology. If the Doppler technology is being used in medical field, it would be for the ultrasound of the heart and blood vessels for examination.
