2.CaF2 has a Ksp = 3.8*10^-11 at 25°C. What is the [F-] in a saturated solution of CaF2 at 25°C?
3.E° = 0.93 V for the reaction Fe(s) + 2M+(aq) >> Fe2+(aq) + 2M(s). The standard reduction potential is -0.41 V for the reaction Fe2+(aq) + 2M(s) >> Fe(s). What is the standard potential for M+ + e- >> M?
4. CuCNS+KIO3+HCl --> HCN+CuSO4+ICl+H2O+KCl . Balance this equation
there 16 more questions but i got them. i dont understand these four.
I hate my science teacher. Help me. Thank you.
8th grade sucks.
