Answer:
0.313 mole of NH3
Explanation:
We'll begin by writing the balanced equation for the reaction. This is given below:
2NH3(g) + 3CuO(s) → 3Cu(s) + N2(g) + 3H2O(g)
The number of mole of ammonia (NH3) required to react with 0.470 mole of copper(ll) oxide (CuO) can be obtained as follow:
From the balanced equation above,
2 moles of NH3 reacted with 3 moles of CuO.
Therefore, Xmol of NH3 will react with 0.470 mole of CuO i.e
Xmol of NH3 = (2 x 0.470) /3
Xmol of NH3 = 0.313 mole.
Therefore, 0.313 mole of NH3 is needed for the reaction
Hey there!:
Molar mass urea = 60 g/mol
Number of moles of solute:
moles solute = mass solute / molar mass
moles solute = 16 / 60
moles solute => 0.2666 moles of urea
Volume in liters:
42.3 mL / 1000 => 0.0423 L
Therefore:
Molarity = moles of solute / volume of solution
Molarity = 0.2666 / 0.0423
= 6.302 M
Hope that helps!
C₆H₆ + 3H₂ → C₆H₁₂
Benzene + 3 molecules of hydrogen = cyclohexane
So essentially what happens is that benzene contains three double bonds and when reacted with hydrogen then these three double bonds can be broken and the hydrogen bond to the tetravalent carbon to restore its for bonds forming cyclohexane
Answer:
b
Explanation:
because it is the balanced one
