Answer:
74.4 ml
Explanation:
C₆H₈O₇(aq) + 3NaHCO₃(s) => Na₃C₆H₅O₃(aq + 3CO₂(g) + 3H₂O(l)
Given 15g = 15g/84g/mol = 0.1786mole Sodium Bicarbonate
From equation stoichiometry 3moles NaHCO₃ is needed for each mole citric acid or, moles of citric acid needed is 1/3 of moles sodium bicarbonate used.
Therefore, for complete reaction of 0.1786 mole NaHCO₃ one would need 1/3 of 0.1786 mole citric acid or 0.0595 mole H-citrate.
The question is now what volume of 0.8M H-citrate solution would contain 0.0595mole of the H-citrate? This can be determined from the equation defining molarity. That is => Molarity = moles solute / Liters of solution
=> Volume (Liters) = moles citric acid / Molarity of citric acid solution
=> Volume needed in liters = 0.0.0595 mole/0.80M = 0.0744 Liters or 74.4 ml
This reaction is known as esterification, esterification is done by reacting carboxylic acid with alcohol in the presence of acid. Below reactions depicts the formation of ester (right reaction) and a formation of salt (left) this salt formed is insoluble in ethanol, hence, white precipitates are observed.
Answer:
Looks like a mitrochondria
Explanation:
I think it is the third one because it just makes more sense to me
Answer:
A
Explanation:
Because total energy is always constant, it only changes form but energy is never destroyed nor created. This is 1st law of thermodynamics which is basically principle of conservation of energy.
Hope this helps!
