La solucionde glucosa, un azucar simple, en agua (suero glucosado) se utiliza para alimentar a los enfermos cuando no pueden comer por algun motivo. en la etiqueta de una botella de suero de 750cm3 se lee: disolucion de glucosa en agua, concentracion: 5,5% m/v A)¿cual es el solvente y cual es el soluto en la solucion?
B)¿Cuantos gramos de glucosa hay en un litro de solucion?
C)Si toman con una cuchara de volumen de 30cm3 y dejan que se evapore el agua, ¿cuantos gramos de glucosa quedaran en la cuchara?
D) si un enfermo necesita tomar 50g de glucosa por hora, ¿que volumen de suero de botella se le debe inyectar en una hora?

plasma is the state of matter where the substance is ionized and has no definite shape or volume. the fact of being ionized makes the substance a good electrical conductor.

assuming that your periodic table has eighteen columns, you should highlight   the four elements in the third column from the left of the table.

neutral atoms of elements after calcium contain d electrons. the energy of d orbitals of a particular main shell lies between the energy of the s and p orbitals of the next main shell. for example, electrons in the have energy higher than those in the orbital while lower than those of the orbital.

by the aufbau principle, electrons fill orbitals one at a time, starting from those of the lowest energy. the orbital is therefore filled right after orbitals and before orbitals.  

potassium has electron configuration and calcium . the s orbital of a main shell holds a maximum of two electrons. the next element would thus have the electron configuration and satisfy the requirements.

a neutral atom of the element contains three electrons on top of the most recent noble gas element. it should thus be placed in the third column of the periodic table. both scandium and yttrium would satisfy the conditions. an aufbau diagram indicates that the 4f orbital is filled before the 5d. however, it appears that exceptions exists for both lanthanum and actinium. neutral atoms of the two d-block elements also demonstrate the and should be highlighted as well.

b.

the accuracy of the data.

because of all the things that happen around the us, many people get into arguments which sadly could get physical, but we should actually make a change for that.
