Answer:
Petrochemicals are chemical products derived from petroleum, although many of the same chemical compounds are also obtained from other fossil fuels such as coal and natural gas or from renewable sources such as corn, sugar cane, and other types of biomass.
Answer:
Explanation:
The Ideal Gas Law states that PV=nRT.
Rearrange that into P/n=RT/V.
In this case, the cylinder is rigid so the volume, V, does not change.
Temperature does not change either.
Out of 450 grams of gas, 150 grams leak out. So only 450-150 = 300 grams is left.
n is number of moles which is dependent on mass:
n1/n2 = 450/300 = 3/2
P1/n1 = RT/V = P2/n2
P2 = P1/n1*n2
= 7.2/3*2
= 4.8 atmosphere
Answer: Thus the volume of the balloon at this altitude is 419 L
Explanation:
Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.
The combined gas equation is,

where,
= initial pressure of gas = 751 mm Hg
= final pressure of gas = 495 mm Hg
= initial volume of gas = 340 L
= final volume of gas = ?
= initial temperature of gas = 
= final temperature of gas = 
Now put all the given values in the above equation, we get:


Thus the volume of the balloon at this altitude is 419 L
False, in an exothermic reaction, an increase in temperature does not favor the formation of products. Instead, it favors the backward reaction. An exothermic reaction is a reaction where energy is transferred from the system out to the environment.
