Given
1 M of Aluminium sulphate
Required
The mole fraction of cation
Solution
Ionization of the Aluminum sulfate solution( assume 1 L solution ) :
mol Al₂(SO₄)₃ = M x V = 1 M x 1 L = 1 mol
Al₂(SO₄)₃⇒2Al³⁺ + 3SO₄²⁻
1 mol 2 mol 3 mol
From this equation, total mol in solution = 2+3 = 5 moles
Mol fraction Al(as a cation) :
= 2/5=0.4
Answer:
Mass = 1.84 g
Explanation:
Given data:
Total pressure = 3.44 atm
Volume of flask = 9.62 L
Temperature = 63°C = 63+273.15K = 336.15 K
Mass of CO₂ = 12.5 g
Mass of hydrogen = ?
Solution:
Number of moles of CO₂:
Number of moles = mass/molar mass
Number of moles = 12.5 g/ 44 g/mol
Number of moles = 0.28 mol
Pressure of CO₂:
PV = nRT
R = general gas constant = 0.0821 atm.L/mol.K
P = 0.28 mol × 0.0821 atm.L/mol.K × 336.15 K / 9.62 L
P = 7.73 atm.L/ 9.62 L
P = 0.8 atm
Total pressure = Partial pressure of CO₂ + Partial pressure of H₂
3.44 atm = 0.8 atm + P(H₂)
P(H₂) = 3.44 atm - 0.8 atm
P(H₂) = 2.64 atm
Number of moles of hydrogen:
PV = nRT
2.64 atm × 9.62 L = n × 0.0821 atm.L/mol.K × 336.15 K
25.39 atm.L = n × 27.59atm.L/mol
n = 25.39 atm.L / 27.59atm.L/mol
n = 0.92 mol
Mass of hydrogen:
Mass = number of moles × molar mass
Mass = 0.92 mol × 2 g/mol
Mass = 1.84 g
Answer:
I do not agree with using pesticides as it is a chemical and can inflict poison in the system. A better alternative would be using smoke to keep the pests away or some natural pesticide. The effect would most likely be lower quantities of crops and higher food prices however.
Explanation:
this is the possible answer on edg.
Answer:
The answer to be filled in the respective blanks in question is
3 and 1
Explanation:
So, we know that the formation of cabon-dioxide mole and that of Adenosin-Tri-Phosphate (ATP) moles will be in the ratio of 3:1 i.e., three carbon-di-oxide moles and 1 ATP mole.
Therefore, we can say that one pyruvate mole when passed through citric acid cycle and pyruvate dehydrogenase yields carbon-di-oxide and ATP moles in the ratio 3:1
