The balanced chemical reaction is:
Na2SO4 + Ba(OH)2 = 2NaOH +BaSO4
We are given the amount of the reactants to be used. These values will be the starting point of our calculations.
0.0820 mol/L Ba(OH)2 (2.27 L solution) = 0.18614 mol Ba(OH)2
0.0664 mol/L Na2SO4 (3.06 L solution) = 0.20318 mol Na2SO4
The limiting reactant is the Ba(OH)2. The amount for this compound will be used.
0.18614 mol Ba(OH)2 (1 mol BaSO4 / 1 mol Ba(OH)2 ) (233.43 g BaSO4 / 1 mol BaSO4)= 43.4507 g BaSO4
Answer:
The reaction H2O(g)+C(s) -> CO(g)+ H2(g) is NOT spontaneous because its ΔG = 91 kJ/moles
Explanation:
ΔG is calculated by ΔH - TΔS
ΔG = ΔH - TΔS
ΔG = 131.3 kJ/mole - 298K . 0,134kJ/mole K
ΔG = 91.068 kJ/moles
Be careful with the ΔS, because you have J, and in ΔH, you have kJ
D=m/V
1.027g/mL=m/15.0L
1.027g/mL(1000mL/L)=1027g/L=m/15.0L
m=1027g/L15.0L
m=15405g
