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

An ideal diatomic gas at 80 k is slowly compressed adiabatically and reversibly to half its volume. The final temperature is 104.8k
<h3>Calculation of final temperature </h3>
The formula used for compression is:-
TV^(γ-1)=C
where;
T= temperature=80k
V=volume(given volume is half of its original volume i.e v/2)
γ=CP/CV= ( 7.R/2)/(5R/2)=7/5
C= constant
using the given values in the formula;
80 x V^[(7/5)-1]=T(final) (V/2)^[(7/5)-1]
80=T(final) x (V/V2)^(2/5)
80=T(final) x (1/2)^(2/5)
T(final)= 80 x (2)^2/5
T(final)= 80 x 1.31
final temperature =104.8k
