Here we have to get the moles of water generated by the combustion of vitamin C.
4 moles of water (H₂O) will generate from the combustion of vitamin C.
The vitamin C is the ascorbic acid having the molecular formula C₆H₈O₆. On decomposition it produces water (H₂O) and carbon di oxide (CO₂).
The molecular weight of ascorbic acid is 176.12 g/mole.
In this analysis 0.163g of H₂O produces from 0.400g of vitamin C.
Thus from 176.12 g of vitamin C ×176.12 = 71.768 g of H₂O will produce.
The molecular weight of H₂O is 18 g/mole. Thus 71.768 g is equivalent to = 3.98 ≅ 4
Thus 1 mole of vitamin C (ascorbic acid) produces 4 moles of water on combustion.
The balanced combustion [in presence of excess oxygen (O₂)] reaction can be written as- C₆H₈O₆ + 5O₂ = 4H₂O + 6CO₂.
Thus the moles of water generated from combustion of vitamin C is determined.
Yes this is true as in cold conditions our body doesn't feel the urge of water therefore we may become dehydrated not even knowing about it and of course in hot coditions we sweat therefore we loose water.
Hope this helps :).
Ammonium sulfate precipitation is used to separate proteins by function
However, it is one of the most commonly used methods for laboratory scale protein purification and fractionation. This method is also used to separate proteins by altering their solubility.
<h3>What is separation techniques?</h3>
Separation technique is a process or method used to the components of mixtures.
There are different types of separation technique which includes sublimation, precipitation, sieving, evaporation and many more.
