Write a molecular equation for the precipitation reaction (if any) that occurs when the following solutions are mixed. If no reaction occurs, write noreaction .
Part A
potassium chloride and lead(II) acetate
Part B
lithium sulfate and strontium chloride
art C
potassium bromide and calcium sulfide
Express your answer as a chemical equation. Enter noreaction if no precipitate is formed. Identify all of the phases in your answer.

What are the genotypic and phenotypic ratios

Chlorine and water react to form hydrogen chloride and oxygen, like this: 2cl2 (g) + 2h2o (g) → 4hcl (g) + o2 (g) also, a chemist finds that at a certain temperature the equilibrium mixture of chlorine, water, hydrogen chloride, and oxygen has the following composition: compound concentration at equilibrium cl2 0.55m h2o 0.57m hcl 0.53m o2 0.34m calculate the value of the equilibrium constant kc for this reaction. round your answer to 2 significant digits.
