A wave with a smaller wavelength has more energy than one with a larger wavelength.
Answer:
Incomplete question: 9.9 mL of 0.01 M EDTA, and 10 mL of buffer with a pH of 4.
The concentration of [HY³⁻] is 1.8x10⁻²⁸mol/L
Explanation:
Given information:
10 mL of 0.01 M VOSO₄ = 0.01 L
9.9 mL of 0.01 M EDTA = 0.0099 L
10 mL of buffer = 0.01 L
pH of 4
Question: Calculate HY³⁻, [HY³⁻] = ?
Moles of EDTA:
The concentration of Y⁴⁺:
At pH = 4 Y⁴⁻ = 3.8x10⁻⁹
mol/L
The concentration of [H₂Y²⁻]:
The reaction:
H₂Y²⁻ → H⁺ + HY³⁻
The concentration of HY³⁻
Solving for HY³⁻
[HY³⁻] = 1.8x10⁻²⁸mol/L
Copper(II) oxide or cupric oxide is the inorganic compound with the formula CuO. A black solid, it is one of the two stable oxides of copper, the other being Cu2O or cuprous oxide. As a mineral, it is known as tenorite. It is a product of copper mining and the precursor to many other copper-containing products and chemical compounds
B. concentrated
A. is incorrect because it COULD be saturated. C. is incorrect because a large amount of salt is concentrated into a small amount of water, so it can't be diluted, relatively. D. is incorrect because it does not describe a solution's molality or molarity.
1.1943571. The molar mass of K3PO4 is 212.27. After using stochieometry, you get your answer.
