Even if all burning of fossil fuels was stopped today, why will temperatures continue to increase?.
When the world stops using fossil fuels, some of these toxins will vanish, taking their little masking impact with them.
In the medium run, the researchers believe that global temperatures will rise somewhat when all emissions are stopped.
How does the use of fossil fuels effect global warming?When fossil fuels are burnt, significant volumes of carbon dioxide, a greenhouse gas, are released into the atmosphere. Greenhouse gases trap heat in our atmosphere, which contributes to global warming. Already, the average global temperature has risen by 1 degree Celsius.
With the impacts of anthropogenic climate change become more severe, it is evident that reversing them is preferable to delaying them. If we stopped using fossil fuels today, warming would undoubtedly slow, but greenhouse gas emissions would continue to rise.

What components are necessary for a neutral atom?.
Neutral atom is a state when the atom doesn't possess any negative or positive charge on it.
Atom is made up of electrons, protons and neutrons.
Electrons are negatively charged, protons are positively charged and neutrons are neutral.
For any component: Proton count equals atomic number
Number of protons plus number of electrons equals the atomic number.
The number of neutrons is equal to the atomic number-mass number.
To balance the atom and make it neutral it is necessary that the electrons and protons are equal to neutrons.
For example, if we take Helium, it has 2 electrons, 2 protons and 2 neutrons, thus it is said to be a neutral atom.
Therefore, the necessary components for a neutral atom are electrons, protons and neutrons.

Explain why atoms can have different isotopes. In other words, how is it that helium can exist in three different forms?
Answer:
The number of protons, massive, positively charged nuclear particles defines the identity of the nucleus.
Woah. Vocabulary here.
An isotope is any of two or more forms of a chemical element, having the same number of protons in the nucleus, or the same atomic number, but having different numbers of neutrons in the nucleus, or different atomic weight. There are 275 isotopes of the 81 stable elements, in addition to over 800 radioactive isotopes, and every element has known isotopic forms. Isotopes of a single element possess almost identical properties.
Helium is usually defined as an inert, gaseous element present in the sun's atmosphere and in natural gas, and also occurring as a radioactive decomposition product, used as a substitute for flammable gases in dirigible balloons. Symbol: He; atomic weight: 4.0026; atomic number: 2; density: 0.1785 g/l at 0 °C and 760 mm pressure.
Explanation:
The number of protons, massive, positively charged nuclear particles, gives Z, the atomic number, which defines the identity of the nucleus.
Z=1, "hydrogen",Z=2, "helium",Z=3, "lithium",...........Z=21, "scandium".
The nucleus may contain various numbers of neutrons, massive, neutrally charged nuclear particles, which gives to the existence of isotopes.
For hydrogen, [tex]Z=1[/tex] by defintion. That is there is a proton in all hydrogen nuclei.

For cis‑1,3‑dimethylcyclohexane, which two chair conformations are in equilibrium?.
For the 1,3-cyclohexanes, the most stable conformation of the cis isomer has both methyl groups in equatorial positions. As you know, the geometry of sp³ hybridized carbon is tetrahedral. With cyclohexane, the whole molecule is not as flat as I often sketch in my notebook. Therefore, cyclohexane adopts two conformations. Boat form and chair form. The boat structure is less frequently seen due to its slightly greater steric hindrance, while the chair structure is preferred as it is very stable.
The figure below shows the chair conformation of cis-1 3-dimethylcyclohexane. Also, cis-1,3-dimethylcyclohexane exists in two chair forms. This is because the conformation continuously changes shape and is also called a compound in a dynamic state. The conformation is also temperature dependent.

why are elements in group 1 more willing to give electrons up rather than try to gain electrons to reach a noble gas state of stability
Ionic compounds are created through the gain and loss of electrons. The attraction of the opposing charges causes the two atoms to stick together, forming a strong, long-lasting chemical bond.
What concept is being employed?Elements can either absorb or lose electrons to attain their closest arrangement as a noble gas. When ions come together to complete the octet, they become more stable. In a reaction with nonmetals, metals normally lose electrons to complete their octet while nonmetals typically receive electrons to do the same. Metal atoms lose electrons from their outer shell when they generate ions, which are positive because they have more protons than electrons. The resultant ions are fully enclosed in their shells. The ions' electrical structure resembles that of a noble gas (group zero element), a whole outer covering. Nonmetals have higher ionization energies and electron affinities than metals, which make it simpler for them to accept electrons and more challenging for them to lose them. Nonmetals are further to the right of metals on the periodic table. They almost make up a whole octet of eight electrons and have more valence electrons.

An element with a low ionization energy is more likely to form ______ during reactions, while elements with high ionization energies tend to form _____. Noble gases are excluded from this trend.
An element with a low ionization energy is more likely to form cations during reactions, while elements with high ionization energies tend to form anions. Noble gases are excluded from this trend.
Ionization energy may be defined as the minimum energy needed to remove the electrons which are loosely bounded in the outermost shell of an atom. It is also known as Ionization potential. Whenever an electron is removed it has its own ionization energy and the energy for each electron removed after the first electron is different. The unit of Ionization energy is Joules. Elements having low Ionization energy tend to loose electron quickly and they are highly reactive in nature and when an electron is lost positive charge is acquired on an atom, so cation is formed. Elements with high ionization energy do not loose electrons quickly and they are less reactive in nature, so extra energy is required to remove the electron which forms an anion.

While geothermal energy is energy that comes from heat contained in the bowels of the earth and is generally associated with the presence of volcanoes. Technically, water that comes from, among other things, rain will seep into the rock beneath the ground until it reaches the reservoir rock.
Energy explanationGeothermal electricity generation is done by drilling the ground in areas that have geothermal potential to create hot gas holes which will be used to heat the boiler so that the steam can drive a steam turbine connected to a generator. For geothermal energy that has high pressure, it can directly rotate the generator turbine, after the steam that comes out is cleaned first.
