N(CuSO₄)=135/{63.5+32.1+4*16.0}=0.846 mol
n(CuSO₄*5H₂O)=135/{63.5+32.1+4*16.0+5*(2*1.0*+16.0)}=0.541 mol
n(H₃PO₄)=135/{3*1.0+31.0+4*16.0}=1.378 mol
n(BaCl₂)=135/{137.3+2*35.5}=0.648 mol

<h3>
Answer:</h3>
4.945 atm
<h3>
Explanation:</h3>
- Based on Dalton's law of Partial pressure, the total pressure of a mixture of gases is equivalent to the sum of individual partial pressures of the gases in the mixture.

In this case;
Partial pressure of Oxygen, P(O) = 0.255 atm
Partial pressure of N, P(N) = 3.24 atm
Partial pressure of Ar, P(Ar) = 1.45 atm
Therefore;
P(total) = P(O) + P(N) + P(Ar)
= 0.255 atm + 3.24 atm + 1.45 atm
= 4.945 atm
Therefore, the total pressure of the mixture is 4.945 atm
Answer: from the lies this is synthesis reaction
Explanation:
It's also oxidation-reduction reaction. Li is oxidised and
H is reduced
