Answer:
8 liters of the first salt solution and 12 liters of the second salt solution is needed to get 20L of a solution that is 30% salt
Explanation:
Let x represent the liters of the first salt solution
Let y represent the liters of the second salt solution
x + y= 20......equation 1
x= 20-y
The first solution is 20% salt and the second solution is 45% salt
20/100x + 45/100 y= 30/100 × 20
0.2x + 0.45y= 0.3×20
0.2x + 0.45y= 6............equation 2
Substitute 20-y for x in equation 2
0.2(20-y) + 0.45y= 6
4-0.2y+ 0.45y= 6
4 + 0.25y= 6
0.25y= 6-4
0.25y= 2
y= 2/0.25
y= 8
Substitute y for 8 in equation 1
x + y= 20
x + 8=20
x= 20-8
x= 12
Hence 8 liters of the first salt solution and 12 liters of the second salt solution is needed to get 20L of a solution that is 30% salt.
Answer:
0.713atm for CO and 0.287atm for CO₂
Explanation:
Based on the reaction:
FeO(s) + CO(g) ⇋ Fe(s) + CO₂(g)
Kp is defined as:
= 0.403
When 1.00 atm of CO react with an excess of FeO, the pressures in equilibrium are:
PCO = 1.00atm - x
PCO₂ = x
<em>Where x represents the reaction coordinate.</em>
Replacing in Kp expression:
0.403 - 0.403x = x
0.403 = 1.403x
0.287atm = x
Thus, pressures in equilibrium are:
PCO = 1.00atm - x = <em>0.713atm</em>
PCO₂ = x = <em>0.287atm</em>
