what is solubility, in mol/L, of MgCO3 in a 0.65 mol/L solution of MgCL2 if the ksp of MgCO3 is 2.5*10^-5
a raido show host asked people to call in and wheater they support new legislation to promote cleaner sources of energy. based on this sample, she constructed a confidence interval to estimate the proportion of all listners to her show who support the legislation. is the confi...

THANK YOU :)
if the [H] of a solution at 25degrees is 1.7*10^-4 mol/L, calculate the [OH] in mol/L, the PH, and the pOH?
show why ka(kb)=kw for this pair of conjugate acid-base: H2C6H6O6 and HC6H66 ^-1
the equilibrium system shown below was analyzed and the concentrations of HI(g, and I2(g) were found, in mol/L, to be 4.4, 3.2, 1.5 respectively. the equilibrium constant must be which f the following? H2(g) + I2(g)<> 2HI(g) + 65KJ
why did u chose 05 mol instead of the given which is 1.5 mol
YES IT IS :) THANK YOU VERY MUCH !!
