Some seawater is evaporated. The sea salt obtained is found to be 86% sodium chloride. How much sodium chloride could be contained from 200g of this salt?

Calculate the expected ph values of the buffer systems from the experiments (a, b,c, d), using the henderson- hasselbalch equation, ph-pka+log[a-]/[ha]. use for pka values carbonic acid= 6.37, and acetic acid= 4.75.

The conventional equilibrium constant expression (kc) for the system below is: 2icl(s) ⇄ i2(s) + cl2(g) [cl2] ([i2] + [cl2])/2[icl] [i2][cl2]/[icl]2 none of the listed answers are correct [i2][cl2]/2[icl]

If 90.0 grams of ethane reacted with excess chlorine, how many grams of dicarbon hexachloride would form
