Answer:
It can be removed by acidic chemicals
Explanation:
The absorption spectrum is the result of absorption of light radiation by a material (solid or liquid) as a function of wavelength or frequency. The figure is shown below:
to the proper number of significant figures) to the following? (12.67+19.2)(3.99)/(1.36+ 11.366).
Answer:
In 1000 ml there is 0.10 moles of Fe 2+
Therefore, in 10 ml there is (0.1/1000)*10= 0.001 mol of Fe2+
mole ratio for rxn Fe2+ : MnO4- is
1 : 2
therefore if 0.001 moles of Fe2+ react then 0.001*2 =0.002 moles of MnO4- react with Fe2+
hence, molarity of MnO4- = (mol*vol)/1000
= 0.002*10.75/1000= 2.15*10-5M

Answer: 
Explanation:- Volume percentage is the ratio of volume of solute to the volume of solution defined in terms of percentage.

Given: volume of solute = 29.4 ml
Volume of solution= 359 ml
