Answer:
Mole fraction of C₄H₄S = 0.55
Explanation:
Mole fraction is moles of solute / Total moles
Total moles are the sum of moles of solute + moles of solvent.
Let's find out the moles of our solute and our solvent.
Mass of solute: 55g
Mass of solvent: 65g
Mol = Mass / molar mass
55 g / 84.06 g/mol = 0.654 moles of C₄H₄S
65 g /123 g/mol = 0.529 moles of C₂H₃BrO
Total moles = 0.654 + 0.529 = 1.183 moles
Mole fraction of thiophene = Moles of tiophene / Total moles
0.654 / 1.183 = 0.55
Answer:
The answer is "
"
Explanation:
When
is added in the chemical equation it reacts with sodium acetate so, it will give the following chemical equation:
In this, the
is a weak acid so, it not completely dissociated.
were strong electrolytes they are completely dissociated.
The
is a strong acid so, it is completely dissociated So, the net ionic equation is:

Answer:
It depends on whether the setting is hot or cold .-.
