sladkih [1.3K]
 <span>Use the sequence E (NaCl, Na2SO4, then Na2S). Silver is insoluble as a chloride, so it would be removed first, the others (Pb and Ni) are soluble as chlorides(Note; lead chloride is soluble as a hot solution but will ppt when cold), next, PbSO4 is insoluble but NiSO4 is soluble so use Na2SO4 to separate lead from nickel. Lastly, nickel sulfide is insoluble and can be separated and collected.

Hope I helped :)</span>

How many g of CO2 can be produced from 256 g Fe2O3?
kotykmax [81]

Answer:

if i consider this reaction

Fe2O3+ 3CO---》2Fe+ 3CO2

so let's calculate first moles of Fe2O3 i.e. = 256/159.69= 1.6 moles

So the one moles of Fe2O3 is forming three moles of CO2

hence 1.6 moles will form 4.8 moles of CO2

one mole of CO2 is 44 g so 4.8 moles of Co2 is 44×4.8= 211.2 g

so the conclusion is 211.2 g of CO2 can be produced from 256 g Fe2O3!!

i d k it's right or wrong but i tried my best :)

Long-wavelength infrared cameras detect infrared radiation with a wavelength of 1.0 x 10-5 meters. How much energy is in these w
alexdok [17]

Answer: The energy of the infrared radiation is 19.8\times 10^{-21}J

Explanation:

The relationship between wavelength and energy of the wave follows the equation:

E=\frac{hc}{\lambda}

E= energy

\lambda = wavelength of the wave  =1.0\times 10^{-5}m

h = Planck's constant  = 6.626\times 10^{-34}Js

c = speed of light = 3\times 10^8m/s

E=\frac{6.626\times 10^{-34}Js\times 3\times 10^8m/s}{1.0\times 10^{-5}m}

E=19.8\times 10^{-21}J

Thus energy of the infrared radiation is 19.8\times 10^{-21}J
