Answer:
H_2O + 2CrO_4^2- + 3SO_3^2- -> 3SO_3^2- + 2CrO_2^- + 2OH^-
Explanation:
Reduction half reaction
2H_2O + CrO_4^2- + 3e -> CrO_2^- + 4OH^-
Oxidation half reaction
2OH^- + SO_3^2- -> SO_4^2- + H_2O + 2e
Balanced overall equation
H_2O + 2CrO_4^2- + 3SO_3^2- -> 3SO_3^2- + 2CrO_2^- + 2OH^-
Formula of Molarity =
Molarity = no. of moles /volume of solution in L
Given, 0.45M= no. of moles/0.750L
Therefore, no. of moles = 0.45M x 0.750L= 0.3375

Answer:
a list of characteristics that can be used to identify a substance include color, odor, taste, density, melting point, boiling point, conductivity, and hardness.
<h3><u>Answer;</u></h3>
10 ft
<h3><u>Explanation;</u></h3>
The wave base of a wave is the depth at which there is no more perturbation of the medium caused by the wave. The wave base of a wave is determined to be half the wavelength of the wave itself.
Therefore;
Wave base = wavelength/2
= 20 ft/2
<u> = 10 ft</u>
