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!!!

How do I do these? Please help
ICE Princess25 [194]

Explanation:

4a)the displacement is the distance moved in a direction but since no direction is given, the displacement is equal to the distance

b) the distance moved is 400m because that's the length of the track

**URGENT** Now lets look at a skydiver who jumps out of a plane that has a forward velocity of 40 m/s. ignore air resistance. Af
Dennis_Churaev [7]
If there's no air resistance, then the diver keeps moving horizontally at 40 m/s, even after s/he jumps out of a perfectly good airplane.

Also, gravity ADDS 9.8 m/s of downward speed for every second the diver falls.

One second after leaving the airplane, the diver is moving horizontally at 40 m/s, and moving vertically downward at 9.8 m/s .

The question asks for the "downward velocity".  That's 9.8 m/s .


The diver's TOTAL velocity is

                       √ (40² + 9.8²)

                   =  √ (1,600 m²/s² + 96.04 m²/s²)

                   =  √ (1,696.04 m²/s²)

                   =        41.2 m/s  in some direction between
                                           straight forward and straight down.

can the suns gravitational pull on the earth affect the temperature as the gravitational pull could suck us in like a black hole
Harlamova29_29 [7]
A black hole doesn't suck things in any harder than any other object does, unless you're closer to it. The Earth hasn't gotten any closer to the sun in many years. This is not the reason for climate change.
