Uma alíquota de 10,00 ml de uma solução contendo éster acetato de etila é pipetada para um balão de fundo redondo contendo exatamente 50,00 ml de solução de koh 0,2378 mol/l. um condensador de refluxo é adaptado e o frasco é aquecido por 30 minutos para que o éster seja completamente hidrolisado
o hidróxido que não reagiu é então titulado, até a viragem da fenolftaleína,
com 32,75 ml de hcl 0,3172 mol/l. calcular o número de milimol do acetato de etila nos 10,00 ml de amostra.

Imagine that you’re getting ready to move to a new city. when people move, they are influenced by push factors and pull factors, and you have many reasons for your move. which of the following factors is an example of a pull factor? a. wanting to move because you’ve found a great new school somewhere new b. needing to move because there are not enough resources in your old hometown c. being forced to move because your old home is gone d. having to move because there are no jobs in your current hometown

The formation of a solid, also known as a is an indication of a chemical change. precipitate particulate particle powder

According to the valence shell electron pair repulsion (vsepr) theory, a molecule that has four electron groups around the central atom will exhibit what electron geometry? view available hint(s) according to the valence shell electron pair repulsion (vsepr) theory, a molecule that has four electron groups around the central atom will exhibit what electron geometry? trigonal bipyramidal tetrahedral square planar determination of electron geometry requires information on whether the electron groups are lone pairs or bonding groups.
