Answer:

a. Hydrogen

Explanation:

Emission spectrum of hydrogen produces four main visible wavelengths out of which one is violet light at 412 nm.

Mercury has visible prominent lines of blue, green and yellow-orange.

Sodium has two prominent very close yellow wavelengths in its emission spectrum.

Neon spectra also consists of green to red lines but not violet light.

Thus, correct option is a.

A 24.00 mL sample of a solution of Pb(ClO3)2 was diluted with water to 52.00 mL. A 17.00 mL sample of the dilute solution was fo
lara [203]

Answer:

0.238 M

Explanation:

A 17.00 mL sample of the dilute solution was found to contain 0.220 M ClO₃⁻(aq). The concentration is an intensive property, so the concentration in the 52.00 mL is also 0.220 M ClO₃⁻(aq). We can find the initial concentration of ClO₃⁻ using the dilution rule.

C₁.V₁ = C₂.V₂

C₁ × 24.00 mL = 0.220 M × 52.00 mL

C₁ = 0.477 M

The concentration of Pb(ClO₃)₂ is:

\frac{0.477molClO_{3}^{-} }{L} \times \frac{1molPb(ClO_{3})_{2}}{2molClO_{3}^{-}} =0.238M

Question 5 why does grinding solid crystals increase the rate of dissolving for a solid solute in water? smaller crystals are mo
My name is Ann [436]
Grinding solid crystals increase the rate of dissolving for a solid solute in water because smaller crystals have more surface area. The solubility of a substance depends on the physical and chemical properties of the solute and solvent as well as the temperature, pressure and the pH of the solution. For example increase in temperature increases the rate at which a solute dissolves in a solvent.
