The answer is D
Because the bread cannot go back to its previous state, and because a new substance was formed. :)
Phosphoric acid or orthophosphoric acid (H₃PO₄) is triprotic acid, which means it lose three protons in chemical reaction (in reaction of esterification with alcohol) and sulfuric acid (H₂SO₄) is diprotic acid, which means it lost two protons in chemical reaction and does not have enough palce to bind alcohol.
Option B.
Current atomic models show the positive charged particles (protons) concentrated in the center (nucleus) of the atom, along with the neutrons, and the negative charged particles (electrons) distributed around (far from) the nucleus.
The molality of a solution : m = 2 mol/kg
<h3>Further explanation</h3>
Given
6 moles of NaOH
3 kg water
Required
The molality
Solution
Molality shows the number of moles dissolved in every 1000 grams of solvent( 1 kg solvent)
m = n. (1000 / p)
m = Molality
n = number of moles of solute
p = Solvent mass (gram)
Input the value :
m = 6 moles : 3 kg
m = 2 mol/kg
