Answer:
About 0.53 g of carbon dioxide needs to be added.
Explanation:
Recall the ideal gas law:
To determine the amount of carbon dioxide we need, we need to solve for <em>n: </em>
<em /><em />
<em />
Recall that <em>P</em>, <em>V</em>, and <em>T</em> are in atm, L, and K, respectively. <em>R</em> is the universal gas constant.
Convert all values into the correct units:
Volume:
Temperature:
And pressure:
Substitute and evaluate:
Convert moles to grams:
In conclusion, about 0.53 g of carbon dioxide needs to be added.
Answer:
1.5 atm is the pressure of dinitrogen tetroxide after equilibrium is reached the second time.
Explanation:
initially
4.9 atm 0
At equilbrium:
(4.9-2p) p
Pressure of nitrogen dioxide gas at equilibrium = 2.7 atm
So, (4.9-2p) = 2.7 atm
p = 1.1 atm
The value of equilibrium constant :
After addition of 1.2 atm of nitrogen dioxide gas more to the flask,will the reestablish an equilibrium in flask.
(2.7+1.2) atm 1.1 atm
At second equilibrium
(2.7+1.2-2x) atm (1.1+x) atm
The expression of :
Solving for x:
x = 0.3827 atm
The pressure of dinitrogen tetroxide after equilibrium is reached the second time:
(1.1+x) atm = (1.1+0.3827) atm =1.4827 atm ≈ 1.5 atm
1.5 atm is the pressure of dinitrogen tetroxide after equilibrium is reached the second time.
Answer:
.574
Explanation:
smallest number of digits in the expression was 3, so the final answer should have 3 sig figs
Answer:directly proportional to the pressure of the gas above the liquid
