Answer:
0.01M = [H⁺]; 1x10⁻¹²M = [OH⁻]; Ratio is: 1x10¹⁰
Explanation:
pH is defined as -log [H⁺]
For a pH of 2 we can solve [H⁺] as follows:
pH = -log [H⁺]
2 = -log [H⁺]
10^-2 = [H⁺]
<h3>0.01M = [H⁺]</h3>
Using Keq of water:
Keq = 1x10⁻¹⁴ = [H⁺] [OH⁻]
1x10⁻¹⁴ / 0.01M = [OH⁻]
<h3>1x10⁻¹²M = [OH⁻]</h3><h3 />
The ratio is:
[H⁺] / [OH⁻] = 0.01 / 1x10⁻¹² =
<h3>1x10¹⁰</h3>
Evaporation is when hot water turns to steam.
MC₂H₄O₂ = 2 * 12 g/mol + 4 * 1 g/mol + 2 * 16 g/mol = 60 g/mol
c = 0.5 mol/L
V = 1 L
n = c * V
n = 0.5 mol/L * 1 L = 0.5 mol
m = n * M
m = 0.5 mol * 60 g/mol = 30 g/mol

A decomposer is not a disturbance of the ecosystem because it decomposes dead animal bodies and recycles it into the soil which helps the food chain work
Are u sure this is the right option? Well, antimony can be decomposed. Including octane.
