Algunas drogas bloquean los químicos secretados por los axones. ¿Cómo podrían afectar estas drogas al impulso nervioso? ¿Qué pod
olya-2409 [2.1K]

Answer:

Algunas drogas intervienen en el impulso nervioso inhibiendo la liberacion de  neurotransmisores, por ende estas neuronas no generaran efectos postsinapticos.

Podria pasar que algunos procesos internos estaran inhibidos o fomentando indirectamente la aparicion de otros, un ejemplo claro de esto es la xerestomia generada por las drogas betabloqueantes.

Explanation:

Es asi que los procesos internos se veran desregularizados, las drogas que inhiben la liberacion de los neurotransmisores son reguladores por lo general de la tension arterial o antiarritmicos cardiacos, es por eso que su consumo es fundamental y vale el riesgo beneficio a la hora de evaluar la inhibicion de las respuestas postsinapticas.

Los neurotransmisores mas conocidos son la noradrenalina y adrenalia, le membrana presinaptica es la nerviosa y la postsinaptica puede ser muscularo o nerviosa.

How many moles would be equal to 22.4 g of CO2?
Rzqust [24]

Answer:

Number of moles = 0.51 mol

Explanation:

Given data:

Mass of CO₂ = 22.4 g

Number of moles = ?

Solution:

Number of moles of CO₂:

Number of moles = mass/molar mass

Molar mass of CO₂ = 44 g/mol

by putting values,

Number of moles = 22.4 g/ 44 g/mol

Number of moles = 0.51 mol

Express the concentration of a 0.0320 M aqueous solution of fluoride, F−, in mass percentage and in parts per million (ppm). Ass
denis23 [38]

Answer:

607 ppm

Explanation:

In this case we can start with the <u>ppm formula</u>:

ppm=\frac{mg~of~solute}{Litters~of~solution}

If we have a solution of <u>0.0320 M</u>, we can say that in 1 L we have 0.032 mol of F^-, because the molarity formula is:

M=\frac{mol}{L}

In other words:

0.0320~M=\frac{mol}{1~L}

mol=0.032~M*1~L=0.032~mol

1~L~of~Solution=0.0320~mol~of~solute

If we use the <u>atomic mass</u> of F  (19 g/mol) we can convert from mol to g:

0.0320~mol~F^-\frac{19~g~F^-}{1~mol~F^-}~=~0.607~g

Now we can <u>convert from g to mg</u> (1 g= 1000 mg), so:

0.607~g\frac{1000~mg}{1~g}=607~mg

Finally we can <u>divide by 1 L</u> to find the ppm:

ppm=\frac{607~mg}{1~L}=~607~ppm

<u>We will have a concentration of 607 ppm.</u>

I hope it helps!
