N yogurt de 125 g muestra en su etiqueta el contenido de algunas de sus sustancias nutricionales:¿Cuál es la composición en tant

poizon [28]

Answer:

Sustancia Masa (g) Composición (% m/m)

Proteínas 5,5 4,4

Azúcares 5,0 4,0

Sodio 0,06 0,048

Potasio 0,15 0,12

Explanation:

Para calcular la composición porcentual en masa de las sustancias debemos usar la siguiente ecuación:

$\%_{m/m} = \frac{m_{s}}{m_{sol}} \times 100$

En donde:

$m_{s}$ es la masa de la sustancia

$m_{sol}$ es la masa del yogurt = 125 g

Para las proteínas:

$\%_{m/m} = \frac{m_{s}}{m_{sol}} \times 100 = \frac{5,5 g}{125 g} \times 100 = 4,4 \%$

Para los azúcares:

$\%_{m/m} = \frac{5,0 g}{125 g} \times 100 = 4,0 \%$

Para el sodio:

$\%_{m/m} = \frac{0,06 g}{125 g} \times 100 = 0,048 \%$

Para el potasio:

$\%_{m/m} = \frac{0,15 g}{125 g} \times 100 = 0,12 \%$

How the proton H gradient is used to make ATP

sladkih [1.3K]

Answer:

The proton gradient produced by proton pumping during the electron transport chain is used to synthesize ATP. Protons flow down their concentration gradient into the matrix through the membrane protein ATP synthase, causing it to spin (like a water wheel) and catalyze conversion of ADP to ATP.

Which property of water makes it helpful to use in car radiators?

Nezavi [6.7K]

The correct answer is C) Water takes long to heat and cool down than other liquids.

It doesn't climb up the sides of a tube any more than other solutions do, and being a universal solvent has nothing to do with radiators. It does however take a long time to heat and cool down since you don't have a 100+ celsius burner to heat it up in an instant.

When Na forms an ion it loses its outer electron to become Na+. Write the electron configuration for Na and Na+. What element do

Otrada [13]

Answer:

Na: 1s2 2s2 2p6 3s1

Na+: 1s2 2s2 2p6

Na+ electronic configuration resemble that of Neon( 1s2 2s2 2p6)

In general, the electronic configuration of alkali metals ions resemble that of the group zero (noble gas)
