The reaction between the lead iodide, PbI2 and sodium carbonate, Na2CO3, will form the chemical compounds, sodium iodide and lead carbonate as shown below.
PbI2 + Na2CO3 --> NaI + PbCO3
The white precipitate formed in the reaction is PbCO3.
Answer:
lithium oxide is soluble in water
Gas -- move very independently as compared to a liquid, for instance.
Plasma -- related to a gas although it has positively charged ions and negatively charged electrons.
