Explain the environmental issues faced by the society due to rapid industrialization and raise in population ? (3m)

1 answer:

8 0

Rapid industrialization and raise in population increases the sources of population and the rate of discharge of wastes. Mass production of products also results in the production of wastes and some industries and countries don't have the technology to treat these wastes before discharging them into the environment.

If a star is able to stabilize after there is no more hydrogen in its core, then it is now fusing helium nuclei together in a re

avanturin [10]

Answer: The correct answer is Option b.

Explanation:

Nuclear fusion reaction is defined as the reaction in which lighter nuclei combine together to form a single heavier nuclei.

Another name for helium nuclei is alpha particle.

For the given options:

Option a: The CNO cycle

This cycle is named as carbon-nitrogen-oxygen cycle. In this cycle, carbon absorbs a proton to form nitrogen which further absorbs a photon to form oxygen. Thus, helium particles are not getting fused in this process.

Option b: The triple alpha process

This process is a set of nuclear reaction in which 3 alpha or helium nuclei combine together to form carbon nucleus.

The equation representing the fusion process follows:

$_2^4\textrm{He}+_2^4\textrm{He}\rightarrow _4^8\textrm{Be}+\gamma\\\\_4^8\textrm{Be}+_2^4\textrm{He}\rightarrow _6^{12}\textrm{C}+\gamma$

Option c: Photo dissociation

This is defined as the process in which a chemical compound is broken down by photons. Thus, helium particles are not getting fused in this process.

Option d: The proton-proton chain

This process is a set of nuclear fusion reactions by which stars convert hydrogen nucleus to helium nucleus. The chemical reactions for this process are:

$_1^1\textrm{H}+_1^1\textrm{H}\rightarrow _1^2\textrm{H}+_{+1}^0\textrm{e}+\text{energy}\\\\_1^2\textrm{H}+_1^1\textrm{H}\rightarrow _2^3\textrm{He}+\text{energy}\\\\_2^3\textrm{He}+_1^1\textrm{H}\rightarrow _2^4\textrm{He}+_{+1}^0\textrm{e}+\text{energy}$

Here, fusion of protons takes place.

Hence, the correct answer is Option b.

They were very nasty back then. The factories that they would make to food had sick animals with boils and other bacteria. They would still cook the food and sell it. The people would get sick. They didn’t wash their areas. Nowadays an inspector comes in the restaurants and check their foods, etc. and people are more sanitary than before
