When PbSO₄ is added it dissociates as follows
PbSO₄ --> Pb²⁺ + SO₄²⁻
molar solubility is the number of moles of solute that can be dissolved in 1 L of solution
if molar solubility of PbSO₄ is X, then molar solubility of Pb²⁺ is X and SO₄²⁻ is X
the formula for ksp is as follows
ksp - solubility product constant
ksp = [Pb²⁺][SO₄²⁻]
ksp = X * X
ksp = X²
ksp = 1.82 x 10⁻⁸
X² = 1.82 x 10⁻⁸
X = 1.35 x 10⁻⁴ M
molar solubility of PbSO₄ is 1.35 x 10⁻⁴ M
answer is b.
Place a 2 in front of the HCl.
This is because the product is yielded to be both H2 and Cl2, diatomic elements. In the reactants side, HCl has no coefficient, but by adding 2, the equation will become balanced.
Hope this helps!
Answer
Establishing laws
Explanations
The steps involved when performing a scientific research are;
• Making observations
• Forming a question after making an interesting observation, a scientist should find more about the concept identified.
• Forming a hypothesis
• Conducting the experiment
• Analyzing the data
• Drawing a conclusion
Answer:
the answer would be C: point source
Explanation:
because it specified the source of the pollution (manufacturing plant)
