Water is 22.4
Final for both us 27.1
Explanation:
I just finished this part of the lab
Answer: 4.74 moles
Explanation:

Moles of Ba=
Moles of Ba=
According to given balanced equation,
1 mole of Barium gives 2 moles of Li
Thus 2.37 moles of Barium gives=
Thus 4.74 moles of lithium will be produced by 135 g of barium.
25.0 g.....................................................
<span>C = 4.18
delta T = 24.25 - 23.16 = 1.09
mol = 0.070L * 0.185M = 0.01295
m = d*v = 1.00*(0.070+0.070) = 0.14g
So, delta H = q/mol HCl = [mC(deltaT)]/mol HCl = (0.14*4.18*1.09)/(0.01295) = 49.3 kJ</span>
