Answer: Option B

Explanation:

Earth is a unique planet with all the conditions that favors living conditions.There are many factors present on earth that favors life on earth but it is not necessary that the other planet will also have such factors affecting life.

Earth has moderate temperature that favors water to be present in liquid state. Else the other plants have no water or have snow.

So, Earth has water and Venus has no water because of temperature.

This reason would mainly be because the "earth would have moderate temperature" as more Venus does not. When having the correct answer moderate temperature, this would allow for the water to be supplied. But, as for it not to have the correct and moderate temperature, this would then allow for it not to have to supply of water.

What is the nuclear binding energy in joules for an atom of helium–4? Assume the following: Mass defect = 5.0531 × 10-29 kilogra

almond37 [142]

The mass defect refers to the amount of mass that has been converted to energy to hold the nucleus together. That means the mass defect is what you're using in your equation to calculate E. E=mc2E=(5.0531×10−29)(3×108)2E=4.55×10−12 The binding energy is 4.55 x 10^(-12) J. Let me know if you have any questions!

Can we move only one electron from its orbit to another orbit of lower energy without moving other electrons of the atom? well i

Mrac [35]

Yes, it can happen.

If all the lower energy orbits are already filled with electrons, then it cannot happen since the lower orbitals will already be full, hence another electron will have to move.

However, if the lower energy orbits are not full (for instance if one excited electron goes back to its normal state), then it can happen.

Air is comprised predominantly of nitrogen (N2) and oxygen gas. The ambient air in this room contains about 0.28g of oxygen (O2)

viktelen [127]

Answer:

190 g

Explanation:

Knowing that:

O₂ gas in air: 0.28 g O₂ / L of air
Air inhaled at rest: 19.3 fl.oz. air / breath
Human takes 20 breaths / min

The grams of oxygen gas (O₂) that a human at rest inhales in 1 hour (60 minutes) will be calculated as:

grams of O₂ = breaths in 1 hour * air inhaled per breath * amount of O₂ in air

$grams O_{2} = 60 min* 20 \frac{breath}{min} * 19.3 \frac{fl.oz. air}{breath} * \frac{1 L}{33.814 fl.oz.} * 0.28 \frac{g O_{2} }{L}$

grams of O₂ = 191.78 g

190 g of O₂ are inhaled in 1 hour (written in correct number of significant figures)

*In the calculation the amount of air inhaled per breath was converted from fl.oz. to Liters knowing that 1 L = 33.814 fl.oz.
