Answer:

Carbon, nitrogen and water are recycled trough ecosystems many times. Of all these nitrogen is eventually broken down completely.

Final Answer: Nitrogen

Explanation:

All carbon, nitrogen and water are recycled by the biosphere.

But all of these nitrogen is eventually broken down because there are three bonds are present in nitrogen and these bonds are stronger so cannot be easily broken down.

I don’t get this pls help
igor_vitrenko [27]

Answer:

light

According to Newtonian gravity, light is not affected by gravity, as light is massless. Einstein's law E = mc 2, immediately suggests that light is affected by gravity. This is indeed the case and has experimentally be observed via gravitational lensing and other effects.

Explanation:

I thought I'd just answer here as well so I can get a couple extra points :)

I'm super glad I helped <3

1. A light bulb is filled with 3.54 g of argon at 25 C and 725 mmHg. What is
Ugo [173]

Answer: The volume of given gas is 2.27 L.

Explanation:

Given: Mass = 3.54 g

Temperature = 25^{o}C = (25 + 273) K = 298 K

Pressure = 725 mm Hg (1 mm Hg = 0.00131579) = 0.95 atm

As moles is the mass of substance divided by its molar mass.

So, moles of argon (molar mass = 40 g/mol) is as follows.

Moles = \frac{mass}{molar mass}\\= \frac{3.54 g}{40 g/mol}\\= 0.0885 mol

Formula used to calculate the volume of given gas is as follows.

PV = nRT

where,

P = pressure

V = volume

n = no. of moles

R = gas constant = 0.0821 L atm/mol K

T = temperature

Substitute the values into above formula as follows.

PV = nRT\\0.95 atm \times V = 0.0885 mol \times 0.0821 L atm/mol K \times 298 K\\V = 2.27 L

Thus, we can conclude that the volume of given gas is 2.27 L.

How do everyday activities like driving a car and using electricity lead to global warming ?
Sati [7]
Both driving a car and using electricity produce several greenhouse gases which can lead to global warming.Greenhouse gases are gases that, when released into the atmosphere, trap the heat from the sun's energy. Every day the energy from the sun reaches the earth. Some of the energy is reflected back into space and some of the energy is trapped by the earth's atmosphere. Most of the time the energy being trapped by the atmosphere serves to warm up the earth, so that the temperature does not fluctuate dramatically. In this way the atmosphere acts like a greenhouse - trapping the warmth in. One of the ways that electricity is made is by burning fossil fuels, like coal or fuel. When a fuel is burnt, some of the products are: carbon dioxide, carbon monoxide, and water - all of these gases are greenhouse gases. In a similar way driving a car also burns fossil fuels, and this will produce the same gases.<span>Before lots of fossil fuels were burnt the greenhouse gases in the atmosphere would have been moderated by the carbon cycle. However, if we burn excess fossil fuels we are producing excess greenhouse gases. This can cause more heat to be trapped by the atmosphere and therefore the global temperature will start to rise - global warming. hope i helped </span>
