What is the mass of kcl that can be added to1.0 l of a 0.010 m pb2+ solution to start precipitation of pbcl2? assume that addition of kcl does not affect the solution volume. given: ksp for pbcl2= 1.6 × 10–5. molar mass kcl = 74.55 g/mol a) 3.0 g b) 1.5 g c) 0.8 g d) 1.0 g e) 0.2 g

answer:

  is is answer

explanation:

the mantle

explanation:

earth is divided into three layers: the crust or the outermost layer on which we live; the underlying, middle layer - the mantle - and the core (the innermost layer of earth).

answer: -

reaction:

na + cl ⇌ nacl

balanced chemical equation:

na + 2cl ⇌ nacl2

sodium + clorine goes to form sodium chloride (table salt).

the product is nacl2.

and the reactants are na and cl.

(note: if you don’t know what ⇌ means, read below: -

⇌(double head arrow) means reversible reaction).
