1. Consider coal (-CH-) (- indicates an aromatic carbon-carbon bond and the average aromatic bond energy is 519 kJ/mol) and cellulose or biomass (-CHOH-) as fuel.

Which is more economic (more energy per gram), coal or biomass? Which is environmentally more valuable (less CO₂)?

Expert Solution

Which is more economic (more energy per gram), coal or biomass?

The Coal have more energy then biomass.

The fossil fuels produce great energy and are used in all types of manufacturing as well as everyday life. Things such as gasoline, electricity, natural gas and many others are derived from this source. The fact that they are rapidly becoming depleted and are non-renewable, as well as putting dangerous emissions into the air, has become a concern of governments worldwide.Biomass is also composed of organic matter. However, it has not laid around for millions of years to become part of the earth's structure. It is natural products such as trees, plants, wood waste and other such things. Manure of certain animals is also included in this mix.The chemistry of biomass is not difficult to understand. It receives its energy from the sun that mixes with the plants natural chemistry to form solar energy. The conversion process involves carbon, hydrogen and oxygen within the plant structure. This is stored and can be converted into commercial energy use.With the threat of global warming and studies showing that carbon emission into the air is harmful to the human body, a great deal of interest is being concentrated on biomass as a major energy source. It is clean, only releases natural elements into the air so is not harmful to the atmosphere or humans.

In energy transfer between trophic levels, an average of only about 10% of energy (or carbon) is transferred between trophic levels. What are the factors that affect: A.) Exploitation efficiency (why isn't everything eaten?) B.) Assimilation efficiency (why isn't everything that is ingested assimilated?) C.) Production efficiency (what happens to all that assimilated energy?) Please explain how and why. I need help!!

Consider the markets for fossil fuels (oil, coal, natural gas) and alternative energy sources (solar, wind, geothermal power etc). Due to the current climate change, let's say we desire to have people use less of the fossil fuels (which produce greenhouse gasses that cause global warming) and more of the alternative energy sources. Using the concepts of Supply and Demand, discuss how the government can use policies to shift these curves, and what the results will be on the quantities...

CH 10. 1. The USA Today reports that the average expenditure on Valentine's Day is $100.89. Do male and female consumers differ in the amounts they spend? The average expenditure in a sample survey of 46 male consumers was $135.67, and the average expenditure in a sample survey of 34 female consumers was $68.64. Based on past surveys, the standard deviation for male consumers is assumed to be $38, and the standard deviation for female consumers is assumed to be...
