Potassium standards gave the following emission intensities at 404.3 nm. emission from the unknown was 417. find the [k+] and its uncertainty in the unknown. (use a spreadsheet / graphing program to make a concentration vs. emission signal plot, then find the [k+] and its uncertainty in the unknown.)
sample (µg k/ml) relative emission
blank 0
5.00 124
10.00 243
20.0 486
30.0 712
unknown 417

The answer is bhope this

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 -
