Answer:
Natural causes are unintentional.
Explanation:
An example would be a wildfire. This natural disaster spreads quickly, especially in forests where wood burns easily. Destroying forests through burning causes nutrients to get depleted, and organisms die.
Kw = 1 x 10⁻¹⁴
<span>Kw = [ H₃O⁺] [ OH⁻]
</span>
1 x 10⁻¹⁴ = [ H₃O⁺] * 4 x 10⁻³
[H₃O⁺] = 1 x 10⁻¹⁴ / 4 x 10⁻³
[H₃O⁺] = 2.5 x 10⁻¹² M
hope this helps!
Answer:
Explanation:
The chemical equation is
For simplicity, let's rewrite this as
1. Initial concentration of NH₃
2. Calculate [OH]⁻
We can use an ICE table to do the calculation.
B + H₂O ⇌ BH⁺ + OH⁻
I/mol·L⁻¹: 0.100 0 0
C/mol·L⁻¹: -x +x +x
E/mol·L⁻¹: 0.100 - x x x
Check for negligibility:
\
3. Solve for x
4. Calculate the pH
Freezing the substance and condensing it will not increase the entropy of a substance. In fact, dissolving the substance into water is the only way to increase the entropy of a certain substance. The entropy increases because it diversify with each other.
