Lecithin is an emulsifier agent that's composed of 5 smaller molecules: phosphoric acid, choline, glycerol( is the backbone), and two fatty acids.
The fatty acids, which are hydrophobic (afraid of water), makes this substance more similiar to fats and represent the non-polar part of the lecithin.
The phosphate group is the polar portion of the molecule and it's the negatively charged. The choline is positively charged, which readily dissolve in water<span>.
</span><span>Lecithin is a good emulsifier because of these structural features. the hydrophobic contacts with the oil, while the hydrophilic end contacts with the water.</span>
Answer:
35.29%
Explanation:
no. of questions in test = 34
no. of questions answered correctly = 22
therefore, no. of questions answered incorrectly = 34 - 22
= 12
error percentage = 12/34 * 100
= 35.29%
the law that the product of the pressure and the volume of one gram molecule of an ideal gas is equal to the product of the absolute temperature of the gas and the universal gas constant.
Answer: a)
b) 33749996 grams
Explanation:
a) The balanced chemical reactions will be :
Overall equation :
Overall balanced equation :
b) Amount of iron = 45 metric ton = 45000 kg = 45000000g
To calculate the moles :
According to stoichiometry :
2 moles of are produced from= 3 moles of
Thus 803571 moles of are produced from= of
Mass of
Thus 33749996 g of carbon monoxide are required to form 45.0 metric tons of iron from ferric oxide
