Me podrían decir la fórmula semidesarrollada de: A) 4-etil-2,3-dimetil decano

B) 3,4-dietil-5-isopropil-2,2-dimetil octano

C) 5-sec-butil-3-etil-4,4,5,6-tetramet il nonano

D) 5-ter-butil-4-etil-3,3,4-trimetil decano

E) 6-etil-4-isopropil-2,3,5,7,8-pentam etil undecano

93.2 ml + 3920 ml = 4013 ml total  

(93.2 ml) * (2.03 m) / (4013 ml) = 0.0471 m

the volume in in l of the diluted solution would be 0.0471 m.

chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. these processes are called chemical reactions and, in general, are not reversible except by further chemical reactions. some reactions produce heat and are called exothermic reactions and others may require heat to enable the reaction to occur, which are called endothermic reactions. understanding chemical changes is a major part of the science of chemistry.
