Answer:
After 2000 years, the first after will be 4m lower.
After 2000 years, the second area will be 14m higher.
Explanation:
From the given information:
At the first area:
if the wind is eroding at 2 mm/year, then after 2000 years; we have:
2 mm/year × 2000 year = 4000 mm
4000 mm to meters, we have:
= 4 m lower
At the second smaller area:
Given that the wind is depositing it at the rate of 7 mm per year;
Then:
7 mm/year × 2000 year = 14000 mm
=14 m higher
Answer:
0.008945 atm
Explanation:
In the reaction:
2H2S(g) ⇌ 2 H2(g) + S2(g)
Kp is defined as:
<em>Where P is the pressure of each compound in equilibrium.</em>
If initial pressure of H2S is 3.00atm, concentrations in equilibrium are:
H2S = 3.00 atm - 2X
H2 = 2X
S2: = X
Replacing:
0 = 4X³ - 1.28x10⁻⁶X² + 1.92x10⁻⁶X - 2.88x10⁻⁶
Solving for X:
X = 0.008945 atm
As in equilibrium, pressure of S2 is X, <em>pressure is 0.008945 atm</em>
