A solution is prepared by adding some solid BaF₂ to water and allowing the solid to come to equilibrium with the solution. The equilibrium constant for the reaction below is k = 1.3x10-6. BaF₂(s)= Ba2 (aq) + 2 F (aq) What is the equilibrium concentration of Ba2+ in the solution? Assume that some of the solid remains undissolved. Give your answer in moles per litre, accurate to two significant figures. Do not include units as part of your answer. (Enter 1.23x10-5 as 1.23e-5.) Number

O Hydrocarbons Identifying cis/trans isomerism in a skeletal structure 0/5 Julianna How many cis/trans isomers does this molecule have? Enter the number in the box above the drawing area. Note: be sure you remember to count this structure. That is, an answer of zero is wrong! Also, highlight each bond in this structure that is trans but which could be cis in a different cis/trans isomer. If there are no such bonds, check the No bonds to highlight box under the drawing area. Note: be careful not to highlight a bond just because it's trans in this drawing! It also needs to be a bond that would create a different cis/trans isomer if it were changed to cis. This molecule has cis/trans isomers in all. No bonds to highlight.
