Thank you

what is sulphun?

A sample of pure sodium has a mass of 47.0g. How many moles of sodium does this sample contain

0.0859g of compound X which contains a group II metal dissolves in water to produce colourless solution. Excess acidified silver nitrate was the added and 0.308g of a white precipitate (Y) was formed.
A) identify y
B) write an ionic equation for the formation of y
C) use the data provided to identify the group 2 metal present in compound X
