7nadin3 [17]
Light Spectrum:

Gamma Rays; X- Rays; Ultraviolet Rays; Infrared; Micro; Radio

I'm guessing green means the color wave 
So it should be: Radio-Infrared- Green - UV - Gamma 
This is because frequency decreases when going from left to right on the Light Spectrum!

What is the wavelength (in meters) of an electromagnetic wave whose frequency is 2.63 × 1012 s−1?
aleksklad [387]
To find the wavelength of an  electromagnetic wave for the given frequency can be determined by using the formulaSpeed=Wavelength x FrequencyWavelength=Speed/FrequencyGenerally Speed of the electromagnetic wave is 3x10^8 m/sBy substituting the values Wavelength=3x10^8 m/s / 2.63x10^12 s^-1Wavelength=1.14 x 10^-4 metres

Explain why crystallisation can't be used to prepare calcium carbonate.​
liq [111]

Explanation:

The mechanisms by which amorphous intermediates transform into crystalline materials are poorly understood. Currently, attracting enormous interest is the crystallization of amorphous calcium carbonate, a key intermediary in synthetic, biological, and environmental systems. Here we attempt to unify many contrasting and contradictory studies by investigating this process in detail. We show that amorphous calcium carbonate can dehydrate before crystallizing, both in solution and in air, while thermal analyses and solid-state nuclear magnetic resonance measurements reveal that its water is present in distinct environments. Loss of the final water fraction—comprising less than 15% of the total—then triggers crystallization. The high activation energy of this step suggests that it occurs by partial dissolution/recrystallization, mediated by surface water, and the majority of the particle then crystallizes by a solid-state transformation. Such mechanisms are likely to be widespread in solid-state reactions and their characterization will facilitate greater control over these processes.
