Você aprendeu na aula de Ciências que as células vegetais apresentam estruturas exclusivas se comparadas com as células animais. Por exemplo os cloroplastos, que são responsáveis pelo processo de fotossíntese. Analise as alternativas a seguir e marque a única estrutura que não pode ser utilizada para diferenciar uma célula vegetal da célula animal. * 1 ponto

a) cloroplastos.

b) vacúolo de suco celular.

c) mitocôndria.

d) parede celular.​

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.

What mass of natural gas (ch4) must you burn to emit 276 kj of heat?

The two naturally occurring isotopes of chlorine are 35cl (34.969 amu, 75.77%) and 37cl (36.966 amu, 24.23%). the two naturally occurring isotopes of bromine are 79br (78.918 rm amu, 50.69%) and 81br (80.916 amu, 49.31%). chlorine and bromine combine to form bromine monochloride, brcl. 1. how many peaks will be present in a mass spectrum for brcl? the four combinations of molecule possible given these four isotopes are: 81br37cl, 81br35cl, 79br37cl, and 79br35cl. 2. what are the masses of the four different brcl molecules? express the masses using six significant figures, in decreasing numeric order (highest to lowest), separated by commas.
