Which equilibrium reaction will experience a shift towards the products in equilibrium position when the concentration of ni2+ i
juin [17]

Answer is <span>
      Ni²</span>⁺(aq) + 6NH₃(aq) ⇌ [Ni(NH₃)₆]²⁺<span>

</span>

<span>When the concentration of Ni²⁺</span><span>(aq) increases, according to the Le Chatelier’s principle system tries to become equilibrium by reducing the increased factor. To do that, the concentration of Ni²⁺</span><span>(aq) should be reduced. Hence, the forward reacted should be promoted to reduce the Ni²⁺</span><span>(aq) concentration</span>.

Explain the effects that different frequencies of electromagnetic radiation have when absorbed by matter.
Neko [114]
In order to answer this question we might first want to think about what is electromagnetic radiation. In essence it’s light, just some of the wavelengths are too long or too short for us to see.

We can think about it as two oscillating sinusoidal (goes up and down) waves, one is electric, the other is magnetic.

Because we’re dealing in waves, that means we can calculate their frequency, wavelength, amplitude (brightness) and period.

To calculate it we can use E=hc/lambda
Where E = jewels of energy
h = Planck’s constant
c = speed of light
Lambda = wavelength

It doesn’t really matter for this question what those things mean, just note that it takes more energy to have a shorter wavelength, or less energy to have a longer wavelength.

So now we can answer the question. Light of a longer wavelength has less energy than that of a shorter wavelength. So, when long wavelengths are absorbed by matter (atoms) they will give those atoms less energy. So, either it will pass through the object entirely or it will make the atoms vibrate a little bit more than they already are and we call that thermal energy, or heat.

If high energy wavelengths are passing through matter then they will be giving those atoms a lot of energy, sometimes even ionizing the atoms.
Which, if you’re a living thing can be very bad for your cells.

I hope that helps.
