O gás oxigênio necessário a respiração para a síntese de glicose pode ser em certas condições explicado pelo modelo de gás ideal
Marat540 [252]

Answer:

Em 64 g de gás oxigênio no cilindro de mergulho, existem 2 moles de gás oxigênio e (1,20 × 10²⁴) moléculas de gás oxigênio.

In 64 g of Oxygen gas in the diving cylinder, there are 2 moles of Oxygen gas and (1.20 × 10²⁴) molecules of Oxygen gas.

Explanation:

O número de moles de um elemento é dado como

Número de moles = (Massa / Massa molar) Massa de gás oxigênio no cilindro de mergulho = 64 g

Massa molar de oxigênio gás = 32.0 g / mol

Número de moles de gás oxigênio no cilindro de mergulho = (64/32) = 2 moles

O número de moléculas em 1 mole de qualquer substância = (6,0 × 10²³)

O número de moléculas em 2 moles de oxigênio no cilindro de mergulho = 2 × (6,0 × 10²³) = 12,0 × 10²³ = (1,20 × 10²⁴) moléculas

Espero que isto ajude!!!

English Translation

The number of moles of an element is given as

Number of moles = (Mass/Molar Mass)

Mass of Oxygen gas in the diving cylinder = 64 g

Molar Mass of Oxygen gas = 32.0 g/mol

Number of moles of Oxygen gas in the diving cylinder = (64/32) = 2 moles

The number of molecules in 1 moles of any substance = (6.0 × 10²³)

The number of molecules in 2 moles of Oxygen in the diving cylinder = 2 × (6.0 × 10²³)

= 12.0 × 10²³ = (1.20 × 10²⁴) molecules

Hope this Helps!!!

Why can a device never be 100% efficient? Explain.
sesenic [268]

Answer:

No machine is free from the effects of gravity, and even with wonderful lubrication, friction always exists. The energy a machine produces is always less than the energy put into it (energy input). ... That is why 100% efficiency in machines shall not be possible.

The potential energy of an apple is 19.6 J, and it is 8 m above the ground. The mass of the apple is _____ kg
Crazy boy [7]
We know, U = mgh
Substitute the known values, 
19.6 = m * 9.8 * 8
m = 19.6 / 78.4
m = 1/4

In short, Your Answer would be 1/4 Kg

Hope this helps!
