Chemistry
1 answer:
trapecia [35]4 years ago

Answer:
Acetylene = 49.9 MJ/kg = 49.9 kJ /g
Benzene = 41.8 MJ/kg = 41.8 kJ /g

Fuel is combusted electrically within a container surrounded by a water jacket. Heat passes to the water and the temperature rise is recorded. Then the amount of heat per gram of substance is determined using this equation:
Q = mC∆T

Where:
Q = heat (Joules)
C = heat capacity of water = 4.18 J/g
∆T = temperature change (ºC)

How many moles of gas sample are 5.0 L container at 373K and 203kPa
Rom4ik [11]
For the purpose we will here use t<span>he ideal gas law:

p</span>×V=n×R×<span>T

V= </span><span>5.0 L

T= </span><span>373K

p= </span><span>203kPa
</span><span>
R is </span> universal gas constant, and its value is 8.314 J/mol×<span>K
</span>
Now when we have all necessary date we can calculate the number of moles:

n=p×V/R×T

n= 203 x 5 / 8.314 x 373 = 0.33 mole
