Water companies measure the volume of water used by households in cubic metres (mº).
25 cm of a different water sample contained 0.016 g of dissolved solids,
Calculate the mass of dissolved solid in 1 m' of this water sample.
1 m3 = 1000 dm
Give your answer in standard form.

Only one reactant yields 2 or more products. meaning you will only have 1 product and it will break down into 2 or more products. eg. h2o -> h2 + o2

Are there any options that could alot..

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 -
