There would be no net movement of glucose

The given statement is wrong. Glucose solutions are not electrolytes and therefore do not conduct electricity.

Is sodium chloride a good conductor of electricity? Simply by dissolving or dissolving it in water, it cannot conduct electricity as a solid.

Saline contains Na+ and Cl- ions. If ions are present in the solution, these ions can move through the solution and carry an electric current. Pure water and sugar solutions do not contain significant ions. Sugar molecules do not break down into ions when dissolved.

When glucose is added to water, it dissolves readily but does not dissociate into ions. Therefore, a glucose solution is not an electrolyte and is not a conductor of electricity.

Substances that dissolve in water to form a conductive solution are called electrolytes. Substances that dissolve in non-conductive solutions are called non-electrolytes. All soluble ionic compounds are electrolytes.

Determine the oxidation number of each element in these compounds or ions. (a) au2(seo4)3 (gold(iii) selenate) au = se = o = (b)
Stels [109]
<span>                                                    Au</span>₂(SeO₄)₃

                                         O = -2 × 4 = -8
                                             Se  =  + 6
So,
                                            (+6 - 8) = -2

Means (SeO₄) contains -2 charge, Now multiply -2 by 3
                                             
                                             -2 ₓ 3 = -6
Means,
                             Au₂ + (-6) = 0
               
                            Au₂  = +6
Or,
                            Au  =  6 / 2

                            Au  = +3
Result:
                            Au  =  +3
                            Se  =  +6
                            O   =  -2

                                                      Ni(CN)₂


Cyanide (CN⁻) contains -1 charge,
So,
                              N  =  -3
                              C  =  +2
Then,
                                         Ni + (-1)₂  =  0

                                               Ni - 2  =  0
Or,
                                                     Ni =  +2
Result:
                            N  =  -3
                            C  =  +2
                           Ni  =  +2

Which of the following types of electromagnetic radiation have higher frequencies than visible light and which have shorter freq
natta225 [31]

Answer:

Higher frequency than visible light -  <em>Ultraviolet light, X-rays, and Gamma rays</em>

Lower frequency than visible light - <em>Infrared radiation, microwaves, and Radio waves</em>

Explanation:

The frequencies of electromagnetic radiations vary according to their wavelengths. The relationship between the frequency and wavelength of the waves is expressed such that:

      λ = c/f, where λ = wavelength, c = speed of light, and f = frequency.

Thus, there is an inverse relationship between the wavelength and the frequency of electromagnetic waves.

The order of the electromagnetic waves based on their frequency from the lowest to the highest is <em>radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma-rays</em>

<u>Hence, electromagnetic waves with higher frequencies than visible light include ul</u><u><em>traviolet light, X-rays, and Gamma rays </em></u><u>while those with lower frequencies include </u><u><em>Infrared radiation, microwaves, and Radio waves. </em></u>
