B. The water and steam contain the same amount of energy.
4 C₃H₅(NO₃)₃(l) = 12 CO₂(g) + 6 N₂<span>(g) + 10 H</span>₂O(g) + O₂<span>(g)
4 x ( 227.0995 ) g ---------------> 10 x ( 18.0158) g
mass of </span><span>nitroglycerin-------------> 120 g
</span>m ( nitroglycerin ) = 120 x 4 x 227.0995 / 10 x <span>18.0158
</span>
m ( <span>nitroglycerin ) = 109007.76 / 180.158
m ( </span>nitroglycerin ) = 605.06 g
hope this helps!
57 degrees celcius is equal to 330 degrees kelvin
67.88 kPa is equal to 67880 Pa
85.3 liters is equal to 0.0853 m^3
Now, the equation we will use to solve this question is:
PV = nRT where:
P is the pressure of gas = 67880 Pa
V is the volume of gas = 0.0853 m^3
n is the number of moles we are looking for
R is the gas constant = 8.31441 J K-1<span> mol</span><span>-1
T is the temperature of gas = 330 degrees kelvin
Substitute with the givens in the above equation to get n as follows:
n = (PV) / (RT)
n = (67880*0.0853) / (8.31441*330)
n = 2.11 moles</span>
Ummm I think it’s either the first one or the third one. Sorry if it’s wrong and good luck!
The body part that sorts food and air is the pharynx, in the pharynx the paths of food and air cross. food travels from the mouth to the esophagus, air travels from the choanae, to the trachea.
