Question: Binary compounds of zinc are known for most of the metalloids and all the nonmetals except the noble gases. The oxide ZnO is a white powder that is nearly insoluble in neutral aqueous solutions, but is amphoteric, dissolving in both strong basic and acidic solutions. The other chalcogenides (ZnS, ZnSe, and ZnTe) have varied applications in electronics and optics. Pnictogenides (Zn
3N
2, Zn
3P
2, Zn
3As
2 and Zn
3Sb
2), the peroxide (ZnO
2), the hydride (ZnH
2), and the carbide (ZnC
2) are also known. Of the four halides, ZnF
2 has the most ionic character, whereas the others (ZnCl
2, ZnBr
2, and ZnI
2) have relatively low melting points and are considered to have more covalent character.
Is there an answer to this question: What applications do chalcogenides have?

Answer: electronics and optics.

Question: Presbyterianism is historically a confessional tradition. This has two implications. The obvious one is that confessional churches express their faith in the form of "confessions of faith," which have some level of authoritative status. However this is based on a more subtle point: In confessional churches, theology is not solely an individual matter. While individuals are encouraged to understand Scripture, and may challenge the current institutional understanding, theology is carried out by the community as a whole. It is this community understanding of theology that is expressed in confessions.
Is there an answer to this question: What is not a sole matter individually in a confessional church?

Answer: theology

Question: Between 1832 and 2002 the currency of Greece was the drachma. After signing the Maastricht Treaty, Greece applied to join the eurozone. The two main convergence criteria were a maximum budget deficit of 3% of GDP and a declining public debt if it stood above 60% of GDP. Greece met the criteria as shown in its 1999 annual public account. On 1 January 2001, Greece joined the eurozone, with the adoption of the euro at the fixed exchange rate 340.75 to 1. However, in 2001 the euro only existed electronically, so the physical exchange from drachma to euro only took place on 1 January 2002. This was followed by a ten-year period for eligible exchange of drachma to euro, which ended on 1 March 2012.
Is there an answer to this question: When did the twenty-year period for eligible exchange of the drachma to euro end?

Answer:
