Answer:
Some of the various things that humans do to the environment is pump CO2 into the air with Fossil Fuels and using Power Plants, Cutting down trees make more CO2 which can make the Earth hotter and cause Global Warming. Some natural things that can tend to affect climate can be changes in Volcanic activity, Solar activity with the sun, and Earth's orbit around the sun.
Explanation:
It may seem crazy how Earth's orbit around the sun make climate change, but how else would 4 seasons exist. The orbit tends to be in an oval shape. The top parts of the oval, would represent winter and fall because of the distance between the sun decreases. The closer sides of the oval however, would represent Summer and spring because those are the warmer months and show that Earth is closer to the sun.
Because as u go across groups the more reactive it is due to the ability of electrons to be given or taken away
<u>Answer:</u> The wavelength of the flame is 462 nm and color of cesium flame is blue.
<u>Explanation:</u>
To calculate the wavelength, we use Planck's equation, which is:
where,
E = Energy of 1 photon = 
h = Planck's constant = 
c = speed of light = 
= wavelength = ?
Putting values in above equation, we get:
The range of wavelength of blue light lies in range of 500 nm - 435 nm
The calculated wavelength lies in the above range. So, the color of the cesium flame is 462 nm
Hence, the wavelength of the flame is 462 nm and color of cesium flame is blue.
Answer:
Caustic soda
Explanation:
The fractional distillation of air is carried out on liquid air. Before air is liquified, the carbon dioxide content of air is removed using caustic soda. The air is then compressed to a pressure of about 200 atm, sudden expansion of the gas leads to cooling. The process continues until air becomes liquid at -200°C.
Fractional distillation of liquid air usually produces nitrogen and oxygen as major products. nitrogen in obtained first since it has a lower boiling point than oxygen. The gases are then dried, compressed and stored in cylinders.
