Answer:

126.8, Iodine

Explanation:

mass ×abundance/100

(126.9045×80.45/100)+(126.0015×17.23/100)+(128.2230×2.23/100)

102.1+21.7+3=126.8

IODINE has an atomic mass of 126.8 or 126.9

Answer:

Grey precipitate implies the presence of silver ions

Yellow precipitate implies the presence of lead II ions

Explanation:

Qualitative analysis provides us a quick method of identifying ions present in a sample by chemical reactions involving simple reagents. Precipitates having a unique colour is formed. The identity of ions in the sample is deduced from the colour of precipitate obtained when particular reagents are added.

In the question, a precipitate containing silver ions upon standing turn into grey colour. Similarly, lead II ions give a yellow precipitate.
