The phenomenon occurring due to an increase in the level of greenhouse gases is known as global warming. This leads to an increase in Earth’s temperature and leading to deleterious changes in the environment. This can be controlled by reducing the use of fossil fuels

Global warming is the phenomenon occurring due to an increase in the level of greenhouse gases. This leads to considerable heating and an increase in temperature of Earth leading to deleterious changes in the environment. This causes odd climatic changes.

The greenhouse gases are those that lead to the heating of Earth’s surface and atmosphere due to the radiation from a planet’s atmosphere and are responsible for the greenhouse effect. According to the given diagram, nitrous oxide contributes a minimum to the greenhouse effect.

The gases that lead to the heating of Earth’s surface and atmosphere due to the radiation from a planet’s atmosphere are known as greenhouse gases. They are responsible for the greenhouse effect. Some gases such as carbon dioxide, methane, nitrous oxide, etc.

The set of quantum number n = 1, l = 2, m = 0, s = 1/2, is not valid because the value of azimuthal quantum number should lie only in between 0 and n-1, where n is principal quantum number. So the above set of quantum numbers is not valid.

Total number of nodes include angular and radial nodes. Angular nodes and radial nodes are given by the formula n – l -1 and l respectively. So the total number of nodes are n – l -1 + l = n – 1. For 3d orbit, “n” is 3, so total number nodes is 3 – 1 = 2.

The magnetic quantum of an orbital range from -( l – 1) to l – 1. Its symbol is given by m. For 2p orbital, there are 3 magnetic quantum numbers namely -1, 0 and 1. For 2pz orbital its 0, taken that z is the internuclear axis.

The sudden increase in current in a Zener diode is due to the rupture of the many covalent bonds present. Therefore, the Zener diode should be connected in reverse bias.

Semiconductor diode can be used as a rectifier. The function of a rectifier is that it converts an alternating current into direct current by allowing the current to pass through in one direction

t_2g is a set of three d orbitals of lower energy in octahedral complexes. The two remaining d orbitals of higher energy form the e_g set.
