A hydrogen atom requires a minimum energy of 2.18×10^-18 J atom to remove an electron from its ground state level. Determine whe
frosja888 [35]
Just find the energy of the <span>blueviolet light with a wavelength of 434.0 nm using the formula:

E  = hc / lambda

E = energy
c= speed of light =  3 x 10^8 m/s
h = planck's constant =  6.6 x 10^{-34}  m^2 kg / s
lambda =  434 nm =  434 x 10^{-9} m

Putting these values (with appropriate units) in the above formula :

we get:  Energy, E = 4.5 x 10^{-19} J

E = 0.45 x 10^{-18} J

Now, the </span>minimum energy is 2.18×10^-{18} J but our energy is 0.45 x 10^{-18} J which is less.
<span>Means the electron will not be removed

aksik [14]

An example of an atom that has no charge is one that has a. 2 protons, 2 electrons, and 1 neutron.

To be neutral an atom must have the <em>same number</em> of protons (+) and electrons (-).

Only then will the <em>charges cancel</em> and give a neutral atom.

How many miles of MgCI2 are there in 345 g of the compound?
Valentin [98]
MgCl2
Mg=24
Cl=35.5×2 = 71
rmm= 71+24=95g
1 mole = molar mass
1 mole = 95g
1g = 1/95 moles
345g= 1/95 × 345

Why sunlight is an essential source of life sustenance on Earth ?​
Elenna [48]

Answer:

The sun is important to Earth because it helps regulate the climate, is the main source of energy for producers in the ecosystems and it keeps the oceans from freezing, along with providing light. If just one of these factors changed dramatically, it would impact all life on Earth. Without the sun, the planet’s oceans would freeze, temperatures would drop and all life would die off without light or food.

The sun is important to every single aspect of life on the planet. Human life could not exist without it because it would cause all of the water and food sources to cease to exist. The sun is in no danger of disappearing any time soon. Scientists estimate the sun has at least another 5 billion years before it turns into a red giant and swallows up Mercury and Venus. It will also destroy all life on Earth because it will be close to the planet once that change occurs. The temperature of the sun will also increase tenfold from 18 million to 180 million degrees Fahrenheit. The increase in the sun’s size when it finally begins to change will be due to the heat increase causing expansion.

Without the sun, we would no energy to live, no plants to eat, no trees to give us oxygen or animals to roam. We would not have gravity to keep the earth in orbit. Without the sun, the earth would be dark and cold and life would quickly disappear.
