a balloon containing 1,000L of gas at 50. C and 760 mmHg rises to an altitude where the pressure is 380mmHg and the temperature is 10. C, what is the new volume of the balloon (in L)?
PV/T =P'V'/T'
380 XFIRST, ALWAYS ALWAYS, ALWAYS CHANGE TEMP IN C TO TEMP IN K
50C =50+273K =323K
10C= 10+273 =283
now PV/T =P'V'/T')
so
760 X 1/323 = 380 X V'/283
so
V' =760 X1 X283/(323X380)
V' = 1.75 L
L
Density is mass per unit volume
2.4=8.5/v
V=8.5/2.4
V=3.54
<u>Answer:</u> 3 moles of water are formed. The limiting reagent is Oxygen atom and the excess reagent is Hydrogen atom.
<u>Explanation:</u>
From the image provided, there are 8 moles of Hydrogen atom and 3 moles of Oxygen atom.
The equation for the formation of water is given by:
By Stoichiometry,
1 mole of Oxygen atom reacts with 2 moles of Hydrogen atom.
So, 3 moles of Oxygen atom will react with = of Hydrogen atom.
The required amount of Hydrogen atom is less than the given amount of Hydrogen atom, hence, it is considered as an excess reagent.
Therefore, Oxygen atom is the limiting reagent because it limits the formation of product.
By Stoichiometry of the reaction:
1 moles of oxygen atom produces 1 mole of water molecule.
So, 3 moles of oxygen atom will produce = of water molecule.
Thus, 3 moles of water are formed. The limiting reagent is Oxygen atom and the excess reagent is Hydrogen atom.
