Rill erosion can eventually evolve into gully erosion. Gully erosion<span> happens when runoff concentrates are flowing in a very strong manner causing it to move some of the soil particles. Advanced </span>rill erosion can<span> become a </span>gully erosion<span>. </span>
The pH of the resulting solution is 2.82.
<h3>What is pH ?</h3>
pH is the measure of acidity and alkalinity of a solution , It has a range of 1 to 14.
HCl + NaOH → NaCl + H₂O
0.0040 .0025 0 0
0.0040 -0.0025 0 0.0025 0.0025
Moles of HCl = 0.0015
As 0.0025 moles of NaOH reacts with 0.0025 moles of HCl leaving behind 0.0015 moles of HCl
Concentration of HCl = 0.0015/ 1 = 0.0015 M
[ H⁺] = 0.0015 M
pH = -log [ H⁺]
pH = -log [ 0.0015]
pH = 2.82
Therefore the pH of the resulting solution is 2.82.

Answer: 2.78 L
Explanation:
Given that,
Original volume V1 = 1.2 L
Original pressure P1 = 5.1 kPa
New pressure P2 = 2.2 kPa
New volume V2 = ?
Since pressure and volume are given while temperature is constant, apply the formula for Boyle's law
P1V1 = P2V2
5.1 kPa x 1.2L = 2.2 kPa x V2
6.12 kPa L = 2.2 kPa x V2
V2 = 6.12 kPa L / 2.2L
V2 = 2.78 L
Thus, the new volume of the gas would be 2.78 Liters
Answer:
<h3>The answer is 19230.8 kg/m³</h3>
Explanation:
The density of a substance can be found by using the formula
From the question
mass = 500 kg
volume = 0.026 m³
We have
We have the final answer as
<h3>19230.8 kg/m³</h3>
