How have humans contributed to an increase in carbon dioxide levels in the past 100 years?

Chemistry
1 answer:
deff fn [24]3 years ago
8 0

Answer:

Carbon dioxide (CO₂) is an important green house gas. A small increase in the concentration of this gas can lead to the global rise in the surface temperature. Over the last 100 years, this gas has increased significantly. One of the main cause behind this the anthropogenic activities.

After the setup of the industrial revolution, there has been a large increase in this CO₂ concentration, as there are numerous large factories and indutries that releases this harmful gases. In addition to this, the burning up of fossil fuel also is responsible for the emission of large amount of carbon into the atmosphere.

Deforestation also is another cause, because trees are no longer there in vast quantities which takes up a large number of atmospheric carbon and in return liberates plenty of oxygen.

Thus, the activities done by man over the last century has led to the increase in the concentration of CO₂ into the atmosphere.

A hypothetical covalent molecule, X–Y, has a dipole moment of 1.93 1.93 D and a bond length of 109 pm. 109 pm. Calculate the par
Gnesinka [82]

Answer:

q= 110.5 ke

Explanation:

Dipole moment is the product of the separation of the ends of a dipole and the magnitude of the charges.

μ = q * d

μ= Dipole moment (1.93 D)

q= partial charge on each pole

d= separation between the poles(109 pm).

e= electronic charge ( 1.60217662 × 10⁻¹⁹ coulombs)

So,

q= \frac{1.93}{109 * 10^{-12} } coulombs

q = \frac{1.93}{109 * 10^{-12} *  1.60217662 * 10^{-19} } e

q = 1.105 * 10⁵ e

q= 110.5 ke

vampirchik [111]

The best description of bond angles around the carbon atoms of 1-butene is double bonded unsaturated carbon atoms and sp2 hybridized

<h3>What are organic compounds?</h3>

Organic compounds are those organics substances containing carbon and hydrogen only.

Some classes of organic compounds are:

  • Alkanes
  • Alkenes
  • Alkenes

So therefore, the best description of bond angles around the carbon atoms of 1-butene is double bonded unsaturated carbon atoms and sp2 hybridized

Convert 6.42 moles of H2O to molecules
Ivahew [28]

Answer:

3.87 x 10^24

Explanation:

Simply multiply the moles by avogadros number

6.42 moles of H2O x 6.022 x 10^23 molecules/1 mole of H2O = 3.87 x 10^24 molecules of H2O
