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.

What is the name given to an ion that has lost electrons? someone help me please D:
marin [14]

The name given to an ion that has lost electrons is cation. Details about cations can be found below.

<h3>What is a cation?</h3>

A cation is a positively charged ion i.e. the one that would be attracted to the cathode in an electrolytic procedure.

Generally, an ion is an electrically charged atom. An ion can either be positively charged or negatively charged. The latter is called an anion while the former is called a cation.

A cation is formed when an atom loses electrons to become positively charged while an anion is formed when an atom accepts electrons to become negatively charged.

Therefore, it can be said that the name given to an ion that has lost electrons is cation.

The balanced equation below represents the decomposition of potassium chlorate.
dezoksy [38]
The oxidation number of chlorine in the reactant can be determined by K ion and O ion. K ion is +1 and O ion is -2. And the Cl is +5. The gas has the greatest entropy and the solid has the least. In the production, there are solid and gas. So it has more entropy than the reactants with solid only.

Which element below is the most reactive?
const2013 [10]

Answer: Chlorine

Explanation: Chlorine has an atomic number of 17 and a configuration of 2, 8, 7. In the outermost shell, it has 7 seven electrons which means that it needs just one more electron to attain an octet configuration in that shell. Therefore it's can react quickly with any nearby nucleophile. Chlorine is more stable as a molecule (Cl2) because that way, it's in a covalent bond with itself and each chlorine atom in the molecule attains an octet. It's is also more stable as a Chloride ion (Cl-). Yes, Hydrogen (H) has a single electron in it's single shell and requires just one electron to attain a stable duplet configuration but it's not as reactive as the Cl because that single electron is closer to the nucleus and it's held firmly by the nuclear charge preventing it from being highly reactive. Unlike hydrogen, chlorine atom has 2 more shells shielding the outermost shell from the effect of the nuclear charge, hence, it's willing to accept electron from a donor. Oxygen need 2 more electrons to attain an octet in it's outermost shell considering it's configuration of 2,6. But in the presence of electrons, Cl would pick up electron faster than Oxygen since it requires just one. Neon on the other hand is a noble gas. It's shells are completely filled. considering it's configuration of 2,8, it has no space to accept electrons and cannot donate either. Hence, no room for reactivity.
