When pbi2 is added to na2co3 a white precipitate is formed. the white precipitate most likely is?

The white precipitate formed is of lead carbonate having formula

Explanation:

When lead iodide reacts with sodium carbonate, it leads to the formation of a white colored precipitate of lead carbonate along with sodium iodide.

This reaction is a type of double displacement reaction in which exchange of ions takes place.

The equation for the above reaction follows:

Hence, the white precipitate is of lead carbonate.

the old alchemists made significant contributions to science even though there starting premises were off a bit. their conclusions after failure would steer them into better directions for investigation. science is no more than close observation and the initial mistakes result in rethinking and retrying experiments.

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.
