Hope this helps
Answer:
Q = 111.8 kJ;
The reaction is endothermic.
Explanation:
The heat of the mixture can be calculated by the equation:
Q = m*c*ΔT
Where Q is the heat, m is the mass of the solution, c is the specific heat, and ΔT is the variation in the temperature (fina - initial).
The mass of H₂SO₄ is the volume multiplied by its density:
mH₂SO₄ = 2000 mL * 1.030 g/mL = 2060 g
Then the total mass is:
m = 2060 + 200
m = 2260 g
Q = 2260*4.184*(36.820 - 25.000)
Q = 111,468.03 J
Q = 111.8 kJ
The reaction is endothermic because the solution is absorbing heat (Q > 0), which can be noticed by the increase in the temperature. When the reaction loses heat, it is exothermic and the temperature decreases.
Answer:
v2 = 100 Ml OR 0.1 Liters
Explanation:
(400 Ml) (10 atm) = (v2) (40 atm)
4000 = 40v2
100 Ml = v2
Liters = ml / 1000
Liters = 100 / 1000
Liters = 0.1
