Answer: The new pressure of the gas in Pa is 388462
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 at STP =
= final pressure of gas = ?
= initial volume of gas = 700.0 ml
= final volume of gas = 200.0 ml
= initial temperature of gas = 273 K
= final temperature of gas =
Now put all the given values in the above equation, we get:
The new pressure of the gas in Pa is 388462
Answer: 67.2 moles
Explanation:
According to the given balanced equation, 2 moles of acetylene combine with 5 moles of oxygen
to produce 4 moles of carbon dioxide
.
Thus if 2 moles of acetylene combine with = 5 moles of oxygen
35 moles of acetylene combine with=
moles of oxygen
But as only 84 moles of oxygen are available, acetylene is not a limiting reagent.
5 moles of oxygen reacts with = 2 moles of acetylene
84 moles of oxygen reacts with=
moles of acetylene
Thus Oxygen is the limiting reagent as it limits the formation of products. Acetylene is excess reagent as it is present in excess.
2 moles of acetylene produce= 4 moles of carbon dioxide
.
33.6 moles of acetylene produce=
moles of of carbon dioxide
.
