equation Fe3O4=Fe+CO2 is an impossible reaction
Answer:
The pistil, B.
Explanation:
The seeds are formed from the ovule which is contained in the ovary; all in the base, the pistil.
1 mole of N2 produces 2 moles of NH3
OR...
14 x 2 grams of N2 produces 2(14 +3) grams of NH3
1 gram of N2 produces 34/28 grams of NH3
therefore, 56 grams produce (34/28 )x 56 =68 grams of NH3
the answer thus would be 68 grams of NH3
Answer: 
Explanation:
Elevation in boiling point is given by:

= Elevation in boiling point
i= vant hoff factor = 3 (number of ions an electrolyte produce on complete dissociation)

= freezing point constant = 
m= molality

Weight of solvent (water)= 1.000 kg
Molar mass of solute
= 142 g/mol
Mass of solute
= 175.0 g


Thus the boiling point of water when 175.0 g of
, a strong electrolyte is dissolved in 1.000 Kg of water is
