Answer: The solution will deviate positively to Raoult's law. The correct option is A.
Explanation:
Raoult's law states that the partial pressure of components of a liquid mixture is equal to the vapour pressure of the individual components multipled by it's mole fraction. Since the solutions of the two liquids interacts less favourably than they do in the individual liquids, there will be less attraction. This will lead to a slightly high vapour pressure as the molecules easily escapes from the surface. Increased vapour pressure deviates Raoult's law positively.
0.284 liter is the answer
Answer:
The chemist needs to react 40 g of sulfur with 60 g of oxygen to make 100 g of sulfur trioxide.
Explanation:
2S (s) + 3O₂ (g) → 2SO₃ (g)
64g + 96g → 160 g
32g + 48g → 80 g
x + y → 100 g
1 mol SO₃ ___ 80g
n _______ 100g
n = 1.25 mol SO₃
1 mol S ___ 32 g
1,25 mol S __ 40 g
1 mol O₂ ___ 32 g
1,875 mol O₂ ___ 60 g
Answer:
Use E = h*c / lambda, where h is Planck's constant, c is the speed of light, and lambda is the wavelength.
E = (6.626 * 10^-34 J*s x 3.00 * 10^8 m/s) / (1*10^-6 m) = 1.99 * 10^-19 J
