Answer:

2 Answers. The column is filled with the carrier (liquid or gas) before the sample is injected. Thus if there is no interaction between the sample and the column, then the fastest that the sample can get to the detector is the dead time denoted by tM in the diagram.

Bismuth (V) nitrate + strontium hydroxide
mamaluj [8]

Answer: 2Bi(NO_3)_5(aq)+5Sr(OH)_2(aq)\rightarrow 2Bi(OH)_5(s)+5Sr(NO_3)_2(aq)

Explanation:

A double displacement reaction is one in which exchange of ions take place. The salts which are soluble in water are designated by symbol (aq) and those which are insoluble in water and remain in solid form are represented by (s) after their chemical formulas.  

A double displacement reaction in which one of the product is formed as a solid is called as precipitation reaction.  

The balanced chemical equation is:

2Bi(NO_3)_5(aq)+5Sr(OH)_2(aq)\rightarrow 2Bi(OH)_5(s)+5Sr(NO_3)_2(aq)
