Answer:
Heating the mixture to a temperature above the boiling point of acetic acid, but below 100°C (the boiling point of water). The vapours from the acetic acid rise, and go into a tube. They are then condensed within the tube, and run off into a separate storage area. Because water can exist as a gas at pretty much any temperature above 0°C, it will result in an impure mixture, but repeatedly doing this will get the acetic acid to the desired purity.
Using the Avogadro's number (6.022*10^23)
9.11* (6.022*10^23)= 5.49*10^24 atoms of V
Answer:
Explanation:
Hello.
In this case, given the volume (1cm³=1mL) and density of the bromine we are to firstly compute the mass since it will allow us to compute the representative particles:
Next, since the mass of one mole of diatomic bromine is 159.82 g (one bromine weights 78.91), we can next compute the moles in that sample:
Finally, via the Avogadro's number we can compute the representative particles of bromine as follows:
Best regards.
Answer:
2 AL + Fe3N2 = 2 ALN + 3 Fe
The scientific question is “what is the growth rate of the fingerlings in 5% and 10% saline solutions?”
