Answer:
The correct option is;
A. Corresponding with orange light, is the wavelength that blue solutions absorb the most
Explanation:
The wavelength of 633 nm is the wavelength of red light emitted by the helium-neon laser also known as the He-Ne laser
According to absorption spectroscopy and the color wheel, a solution or drink sample that is efficient at absorbing light having a wavelength of 633 nm will appear blue, because, light at 633 nm is red and very close to orange which is the complementary color blue light.
The best and most correct answer among the choices provided by your question is the third choice or letter C.
Convection is heat transfer by mass motion of a fluid such as air or water when the heated fluid is caused to move away from the source of heat, carrying energy with it. Convection plays a role in the water cycle when "<span> gases cycle up and down based on air pressure."

Answer:
b. AZ BX
Explanation:
A⁺, B⁺, X⁻, Y⁻ and Z⁻
AX(aq)+BY(aq)→no precipitate
AX(aq)+BZ(aq)→precipitate.
AX(aq)+BY(aq)→no precipitate:
A⁺ (aq) + X⁻ (aq) + B⁺ (aq) + Y⁻ (aq) → AY (aq) + BX (aq)
AX(aq)+BZ(aq)→precipitate:
A⁺ (aq) + X⁻ (aq) + B⁺ (aq) + Z⁻ (aq) → AZ (s) + BX (aq)
Considering the reactions above, the insoluble specie is AZ.
Answer:
The initial E° for the second cell is the same as for the first cell.
Explanation:
Because the overall chemical reaction that occurs in the cell does not change.
H₃O ions are when water is protonated
H₂O + H⁺ --> H₃O⁺
HCl is a strong acid therefore complete ionisation takes place.
HCl ---> H⁺ + Cl⁻
1 mol of HCl dissociates to give out 1 mol of H⁺
since H⁺ together with water forms H₃O⁺ ions,
[HCl] = [H₃O⁺]
therefore concentration of [H₃O⁺] is 0.0005 M
