docker41 [41]

Answer:

Considere uma molécula de glicose (C6H12O6) e indique: a-) O número de átomos de carbono = 6 b-) O número de átomos de hidrogênio = 12 c-) O número de átomos de oxigênio = 6d-) Quantos átomos teremos quando descubro se temos 8 moléculas dessa substância?

  48 oxigênio, 48 carbono e 96 hidrogênio e-) Quantos átomos de cada elemento teremos com 20 moléculas de glicose?

160 de oxigênio e carbono e 240 de hidrogênio.

Explanation:

A glicose é uma das moléculas mais usadas no organismo humano, pois é uma molécula em que sua decomposição é muito mais fácil que os aminoácidos, portanto, eles produzem como produto a moeda de energia que é ATP mais facilmente do que outros alimentos .

A glicose não é encontrada apenas em alimentos açucarados, isso é um mito, na verdade é a unidade de carboidratos (de assados ​​a doces)

An ideal gas in a cylindrical container of radius r and height h is kept at constant pressure p. The bottom of the container is
Juli2301 [7.4K]

Answer:

m =\frac{p*(pi)*r^{2}*h*mw}{R*\frac{T_{1} + T_{O}}{2}}  

Explanation:

The gas ideal law is  

PV= nRT (equation 1)

Where:

P = pressure  

R = gas constant  

T = temperature  

n= moles of substance  

V = volume  

Working with equation 1 we can get  

n =\frac{PV}{RT}

The number of moles is mass (m) / molecular weight (mw). Replacing this value in the equation we get.

\frac{m}{mw} =\frac{PV}{RT}  or  

m =\frac{P*V*mw}{R*T}   (equation 2)

The cylindrical container has a constant pressure p  

The volume is the volume of a cylinder this is

V =(pi)*r^{2}*h

Where:

r = radius  

h = height  

(pi) = number pi (3.1415)

This cylinder has a radius, r and height, h so the volume is  V =(pi)*r^{2}*h

Since the temperatures has linear distribution, we can say that the temperature in the cylinder is the average between the temperature in the top and in the bottom of the cylinder. This is:  

T =\frac{T_{1} + T_{O}}{2}  

Replacing these values in the equation 2 we get:

m =\frac{P*V*mw}{R*T}   (equation 2)

m =\frac{p*(pi)*r^{2}*h*mw}{R*\frac{T_{1} + T_{O}}{2}}
