The process of adding hydrogen to the double bonds in unsaturated fatty acids to extend the shelf-life of food products is calle
Viktor [21]

Hydrogenation is a process that involves adding hydrogen to the double bonds in unsaturated fatty acids to extend the shelf-life of food products.

<h3>What is hydrogenation?</h3>

Hydrogenation can be defined as a chemical process that involves an addition of hydrogen to the double bonds in unsaturated fatty acids to extend the shelf-life of food products.

<h3>The purpose of hydrogenation.</h3>

In Science, some of the purpose of hydrogenation include the following:

  • Conversion of liquid oil into solid fat.
  • To alter a fat's consistency level.
  • To stabilize a fat or an oil.

Use Hess law and the following equations to calculate H for the reactio below
aleksandr82 [10.1K]

Answer: B2H6 (g) + 3O2 (g) → B2O3 (s) + 3H2O (g) (ΔH = -2035 kJ/mol) 3H2O (g) → 3H2O (l) (ΔH = -132 kJ/mol) 3H2O (l) → 3H2 (g) + (3/2) O2 (g) (ΔH = 858 kJ/mol)

If a solution containing 51.429 g of mercury(ii) perchlorate is allowed to react completely with a solution containing 16.642 g
OLga [1]
Hg(No3)2  +NaSO4   --->2NaNO3  +  HgSO4(s)
calculate  the moles  of   each  reactant
moles=mass/molar  mass

moles of  Hg(NO3)2=  51.429g/  324.6  g/mol(molar  mass  of  Hg(NO3)2)=0.158  moles

moles Na2SO4  16.642g/142g/mol=  0.117  moles  of  Na2SO4

Na2SO4  is  the  limiting  reagent in  the   equation   and  by  use  mole  ratio  Na2So4  to  HgSO4  is  1:1   therefore  the  moles  of  HgSO4  =0.117  moles

mass  of  HgSO4=moles  x  molar   mass  of  HgSo4=  0.117 g x  303.6g/mol=  35.5212  grams
