Answer:
[H₂] = 1.61x10⁻³ M
Explanation:
2H₂S(g) ⇋ 2H₂(g) + S₂(g)
Kc = 9.30x10⁻⁸ =
First we <u>calculate the initial concentration</u>:
0.45 molH₂S / 3.0L = 0.15 M
The concentrations at equilibrium would be:
[H₂S] = 0.15 - 2x
[H₂] = 2x
[S₂] = x
We <u>put the data in the Kc expression and solve for x</u>:
We make a simplification because x<<< 0.0225:
x = 8.058x10⁻⁴
[H₂] = 2*x = 1.61x10⁻³ M
Answer:
The law of constant composition says that the composition of a homogeneous mixture is always the same
Explanation:
The law of constant composition that is also known as Proust's Law says that when two substances react with each other, to form a compound they will always do in a constant weight ratio, that is, the ratio of the masses between two substances that form a compound, must be proportional.
1)Mid Ocean Ridge
2) Sea Floor Spreading; New crust is formed
3) It gets subducted and melts back into the mantle
4) 1. Molten Material (funny looking rocks)
2. Drilling Samples (age of rocks)
3. Magnetic stripes
5) Subduction: Old oceanic crust is more dense and sinks
6) Sonar
7) Trench
8) Sea floor spreading
9) Subduction
10) Mid ocean ridge
Saturated fats have single bond between the carbon atoms, this makes them a solid at room temperature. Unsaturated fats have at least one double bond between the carbon atoms, which makes them liquid in room temperature.
