I think B. As an idea is just a way that could be possible
Answer:
The chemistry of iron is dominated by the +2 and +3 oxidation states i.e. iron(II) and iron(III) complexes e.g. Fe2+ and Fe3+ complex ions with selected ligands, usually of an octahedral shape, a few tetrahedral iron(III) complexes are mentioned too. The reactions of the aqueous ions iron(II) and iron(III) with ammonia, sodium hydroxide and sodium carbonate are described and explained as are complexes of iron(III) with the chloride ion and cyanide ion.
principal oxidation states of iron, redox reactions of iron, ligand substitution displacement reactions of iron, balanced equations of iron chemistry, formula of iron complex ions, shapes colours of iron complexes, formula of compoundsExplanation:
Solute is what gets dissovled, in this case the salt, and the solVENT is whatever a material is dissolved into, in this case the water.
Answer:
2.32 m
Explanation:
So, according to definition of mole fraction:

Mole fraction = 0.176
Applying values as:


So,



Also, Molar mass of toluene = 92.14 g/mol
Thus,
The formula for the calculation of moles is shown below:


Also, 1 g = 0.001 kg
So,

Molality is defined as the moles of the solute present in 1 kg of the solvent.
It is represented by 'm'.
Thus,

<u>Molality of benzene = 2.32 m</u>
Answer:
1)Filtration to remove sand
2)Evaporation to obtain sugar
Explanation:
Add water to the mixture and mix,sugar will dissolve.
Filter out the sand.
Evaporate the remaining solution to obtain the sugar.
