Interpretation :
The sources of energy which is the United States most dependent today are to be explained as well as their comparison to 100 years ago needs to be done.
Concept Introduction :
Fossil fuels are the primary energy sources such as, petroleum, coal, natural gas etc. and these sources are the renewable energy sources. Second energy source is the electricity energy source which is generated with the help of primary sources.
Answer to Problem 21A
The various types and sources of energy is used and produced by the United states which are classified into general categories such as, primary and secondary energy sources, renewable and non-renewable and fossil fuels and the US makes great records in the field of production such as, nuclear energy production, crude oil production, renewable energy sources consumption and production etc. since last 100 years.
Explanation of Solution
The various types and sources of energy is used and produced by the United states which are classified into general categories such as, primary and secondary energy sources, renewable and non-renewable and fossil fuels etc. and these sources of energy is measured in different physical units. The nuclear energy production starts in 1957 in the US and grew year by year. Similarly, the renewable energy production and consumption both reached the high record of their high production from solar and wind energy since last 100 years. The annual crude oil production is also making the highest record for its crude oil production.
Hence, the US makes great records in the field of production such as, nuclear energy production, coal production, crude oil production, renewable energy sources consumption and production etc. since last 100 years.

For each of the following statements, indicate whether they are true of false. ⚫ the terms primary, secondary and tertiary have different meanings when applied to amines than they do when applied to alcohols. • a tertiary amine is one that is bonded to a tertiary carbon atom (one with three C atoms bonded to it). • simple five-membered heteroaromatic compounds (e.g. pyrrole) are typically more electron rich than benzene. ⚫ simple six-membered heteroaromatic compounds (e.g. pyridine) are typically more electron rich than benzene. • pyrrole is very weakly basic because protonation anywhere on the ring disrupts the aromaticity. • thiophene is more reactive than benzene toward electrophilic aromatic substitution. • pyridine is more reactive than nitrobenzene toward electrophilic aromatic substitution. • the lone pair on the nitrogen atom of pyridine is part of the pi system.arrow_forward
