  1. Composing Net Ionic Equations for Chemical Reactions
    A concoction condition is a brief way of passing on data with respect to the cooperating reagents in a substance response. The ordinary arrangement is to compose the reactants on the left-hand side of a right-pointing bolt, and the items on the right-hand side. Conditions of issue (stages like strong, gas, fluid) are incorporated, and all particles are adjusted, similar to the charges.
    Presently, a portion of the reactants separate into particles in arrangement. Henceforth, an ionic condition can be worked out for any response. Particles that don’t separate are left all things considered.
    At the point when the observer particles (those that seem unaltered on either side of the bolt) are counteracted from the ionic condition, at that point we are left with what is named the ‘net’ ionic condition.
    Answer and Explanation:
    How about we open out the reactants into their constituent particles, noticing that one of them, PbS isn’t solvent and henceforth doesn’t ionize.
    Pb2+(aq) +2NO−3(aq)+2K+(aq) +S2−(aq) →PbS(s)+2K+(aq) +2NO−3(aq)

    The observer particles (those that show up on the two sides of the bolt) are K+ and NO−3. When we offset these, we are left with the accompanying net ionic condition:
    Pb2+(aq) +S2−(aq)→PbS(s)
