¿recuerdas cuales son los principales sistemas que conforman nuestro cuerpo y sus funciones generales? ​
mixer [17]

Answer:

Los principales sistemas del cuerpo humano son: nervioso, endocrino, circulatorio, digestivo, excretor, respiratorio,  reproductor, muscular, esquelético, linfático, integumentario e inmunológico

Explanation:

En el cuerpo humano, las células se organizan en tejidos, los cuales a su vez forman órganos y finalmente dichos órganos forman sistemas de órganos que llevan a cabo funciones de forma conjunta.

Los principlales sistemas de órganos y sus funciones son los siguientes:

- nervioso: controla los impulsos nerviosos, controlando tanto los movimientos voluntarios del cuerpo como también las funciones cognitivas.

-endócrino: regula diferente funciones del organismo (como por ejemplo, el crecimiento) a partir de la secreción de sustancias químicas denominadas hormonas

-circulatorio: encargado de llevar nutrientes y eliminar desechos de los tejidos a través de la sangre  

-digestivo: encargado de la obtención de nutrientes a través del proceso de digestión de alimentos

-respiratorio: intercambia gases con el medio exterior, obteniendo oxígeno y eliminando dióxido de carbono

-excretor: elimina los desechos del organismo

-reproductor: encargado de perpetuar la especies mediante el mecanismo sexual de reproducción

-muscular: responsable de los movimientos voluntarios e involuntarios  

-esquelético: provee un sostén físico a las diferentes partes del cuerpo  

-inmunológico: encargado de eliminar microorganismos patógenos

-linfático: también implicado en la defensa del organismo contra microorganismos patógenos  

-integumentario: provee una capa que protege al organismo de agentes externos como, por ejemplo, los rayos solares

A sample of a compound contains 32.0 g C and 8.0 g H. Its molar mass is 30.0 g/mol. What is the compound’s molecular formula?
Alja [10]

Answer:  C2H6

Explanation:

g g/mol AVG   0.375         g/mol  

C 32   12        2.667 1 12    2   24

H   8     1             8         3       3    6      6

                     15           30

Obtain the weighted average of C and H by multiplying the grams of substance times its repective molar mass.  The AVG column is this result.  The number for C is 2.667, but we know we need a whole number for both C and H, so divide both averages by (1/2.667) 0.375 to convert C to a whole number.  H also converts to a whole number with this ratio, which is further evidence we now have the correct ratio of C and H:  they are 1:3 C:H, so the empirical formula is CH3.  The actual formula could be a multiple of this, such as C2H6, C3H9, C4H12, etc.  But we are given the molar mass if this compound, 30 g/mole,  ! mole of CH3 would only be 15 g/mole.  One mole of C2H6, however, is exactly 30 g/mole.  That matches the value we were given, so the formula is C2H6.

17.The column that an element is located in tells us
krok68 [10]

Answer:

A. the total number of valence electrons an atom has.

Explanation:

The columns on the periodic table are called groups or families because of their similar chemical behavior. All the members of a family of elements have the same number of valence electrons and similar chemical properties.
