This is due today and I’m so confused, if you know any of the answers, please help me out. Thank you!

1ai) Members have the same general formula and Members have the almost same chemical properties due to same functional group

1aii) unsaturated -having a double or triple bond and capable of taking on elements or groups by direct chemical combination

1bi ) bromine start water = red/brown/ orange colour finishing colour = colourless

1bii) name of product is C2H4Br2

The reactors are C2H4+ Br2–> C2H4Br2

*All the numbers are meant to be small *

Can I have please ?

Answer is: the equilibrium  shifts toward the reactants, to the left side of chemical reaction.it is because lead(ii) nitrate dissociates in water: pb(no₃)₂ → pb²⁺(aq) + 2no₃⁻(aq).according to lechatelier's principle, the position of equilibrium moves to counteract thechange (more lead cations, common ion), the position of equilibrium will move so that the concentration ofproducts decrease and concentration of reactants of chemical reaction increase.read more on -
