Answer:
B. The [H1+] >[OH1-] and the solution is acidic
system will shift the equilibrium to the right, towards the side of the products
Answer:
Explanation:
mass of the solution = volume x density = 200 x 1 = 200 gm
heat absorbed = m x s x Δ t , s is specific heat , Δt is rise in temperature
= 200 x 4.18 x ( 31.3 - 24.6 )
= 5601 J .
This is the enthalpy change required.
