Answer:
65.21 percent
Explanation:
We are to find the percentage yield
We have this equation,
2no+o2 -->2no2
Such that 1500 kilograms/30grams
= Mno2/46
=1500/30 = mno2/46
We cross multiply from here
1500x46 = 30xMnO2
69000 = 30Mno2
69000/30 = MnO2
2300 = Mno2
The percentage yield would be
1500/2300 *100
= 0.6521 x 100
= 65.21%
This answers the question
Answer:
Moles of BCl₃ needed = 0.089 mol
Explanation:
Given data:
Moles of BCl₃ needed = ?
Mass of HCl produced = 10.0 g
Solution:
Chemical equation:
BCl₃ + 3H₂O → 3HCl + B(OH)₃
Number of moles of HCl:
Number of moles = mass/molar mass
Number of moles = 10.0 g/ 36.46 g/mol
Number of moles = 0.27 mol
Now we will compare the moles of HCl with BCl₃.
HCl : BCl₃
3 : 1
0.27 : 1/3×0.27 = 0.089 mol

Answer:
P(total) = 6.2 atm
Explanation:
Given data:
Pressure of nitrogen = 2.5 atm
Pressure of argon = 3.7 atm
Final pressure = ?
Solution;
According to Dalton law of partial pressure,
The total pressure exerted by mixture of gas is equal to the sum of individual pressure of each gas present in mixture.
Mathematical expression:
P(total) = P₁ + P₂+.... Pₙ
Now we will put the values in formula:
P(total) = P₁ + P₂
P(total) = 2.5 atm + 3.7 atm
P(total) = 6.2 atm
