Answer and explanation;
Coal has aromatic hydrocarbons with high molar mass and has a high ratio of carbon to hydrogen. Burning coal produces more soot than burning other fossil fuels does because of it.
Fossil fuel mixtures of hydrocarbons that formed from the remains of plants or animals. Burning fossil fuels increases the amount of carbon dioxide in the atmosphere. This increase may affect temperatures, amounts of rain and sea levels worldwide. Some sulfur and nitrogen are in fossil fuels, and air contains nitrogen.
Coal produces more soot than other fossil fuels as it is a carbon-rich fossil fuel, where some carbon atoms form soot particles during burning. The combustion of coal is less efficient, producing more particulates and carbon dioxide per unit energy output, thus contributing to air pollution and global warming.
Coal typically produces more soot than other fossil fuels when burned due to its composition. Unlike natural gas or oil, coal is a carbon-rich fossil fuel. When this carbon burns, it reacts with oxygen to form carbon dioxide, but not all carbon atoms complete this reaction. Some form tiny carbon particles or soot instead. These soot particles consist of amorphous carbon, which has a disorganized and complex structure, leading to the dark, dust-like quality of soot.
Historically, the burning of coal was ubiquitous in the Industrial Age, leading to severe air pollution with coal soot covering surfaces in industrial cities. This is because the combustion of coal is less efficient than other fossil fuels, producing more particulates and carbon dioxide per unit energy output. Consequently, the combustion of fossil fuels, and coal in particular, contributes to the greenhouse effect and global warming. In fact, coal-fired power plants produce the greatest amount of CO₂ per unit energy output compared to natural gas or oil, making it the least efficient fossil fuel in terms of greenhouse gas emissions.

Mutation can be defined as the change in the genetic sequence that is hereditary. The example of beneficial mutation can be the change of rabbit color to help him hide from the predators.
The mutation can be caused by the exposure of the gene sequence to the mutagen that cause the hereditary change.
The mutagens can be UV radiation, high energy, radiation, chemicals, or environmental factors.
The beneficial mutation can be given as the mutation in which the organism has been benefitted. The change in the color pf rabbit benefit him in hiding from the predators. Thus, option A has been the example of the beneficial mutation.

Answer:
A
Explanation:
Answer : The mass of nitrogen needed are, 267.68 grams
Explanation :
Mass of = 325 g
Molar mass of = 17 g/mole
Molar mass of = 28 g/mole
First we have to calculate the moles of .
Now we have to calculate the moles of .
The balanced chemical reaction is,
From the balanced reaction we conclude that
As, 2 moles of obtained from 1 mole of
So, 19.12 moles of obtained from moles of
Now we have to calculate the mass of .
Therefore, the mass of nitrogen needed are, 267.68 grams
