What are the major advantages of using hydrogen as an energy source?



- High quality, and can be used like fossil fuels, and fuel cells (similar to batteries in that electrons flow between negative and positive poles, but fuel cell generates electricity rather than just storing it as in a battery) use hydrogen to produce electricity.

- The advantages are that when it is burned, it produces water and no SOX or CO2 is released. It can also be transported in pipelines and stored in tanks; and it can be produced using solar and other renewable resources. Also, since it can store energy, it can be used with other types of alternative energies, and on days when there is no sun or wind, hydrogen can be used to produce electricity.

- The disadvantage is that hydrogen gas must be produced. It is not widely used because it is an unstable form of energy. Also one way to produce hydrogen is to use an electrical current to separate hydrogen from water through electrolysis. This way to produce hydrogen is to use a thermal process in which steam is combined with natural gas, removing the carbon and leaving hydrogen. This process depends on a fossil fuel and produces some carbon dioxide. Hydrogen can also be produced from gasification of biomass.

- Lightest, most abundant element in the universe. High-quality fuel that can be easily used in any of the ways in which we normally use fossil fuels, such as to power car engines and to heat water and buildings

- It is a clean fuel; the combustion product of burning hydrogen is water, so it does not contribute to global warming, air pollution or acid rain. Can be stored easily in fuel cells and flammable as oil.

Discuss the seven characteristics of useful information.

Discuss the seven characteristics of useful information. Answer: The seven characteristics of useful information are: relevant, reliable, complete, timely, understandable, verifiable and accessible. These characteristics are qualities that information should possess to be useful in a business environment. Briefly stated, in order for information to be useful it must be: 1) relevant, meaning that it reduces uncertainty and adds to the decision-making process; 2) reliable information is information that is free from error, and is accurate in its nature; 3) complete information is information that does not omit any important data, facts, or aspects about events or activities; 4) information is timely when it is fully available to enable the decision-making process to proceed; 5) understandable information must be both in an intelligible and useful format; 6) information is considered verifiable if two people, acting independently of each other, produce the same inform

Why have accounting software packages been designed with separate transaction modules?

Why have accounting software packages been designed with separate transaction modules? Answer: : Since every organization does not necessarily use all of the transaction cycles in its operations, it is to the advantage of the organization to be able to "pick and choose" from among various software modules that track and record different transaction cycles. For example, a law firm would have no need to implement a production cycle module. Also, the nature of a transaction cycle varies across the broad spectrum of business organizations. Again, a law firm would have a revenue cycle, but it would not involve the purchase, receipt, and payment for products or merchandise; likewise a retail store chain may not sell any consulting services to its customers.

A laboratory assistant prepared solution of 0.8 M, 0.6 M, 0.4 M, and 0.2 M sucrose, but forgot to label them. After realizing the error, the assistant randomly labeled the flasks containing these four unknown solutions as flask A, flask B, flask C, and flask D.

A laboratory assistant prepared solution of 0.8 M, 0.6 M, 0.4 M, and 0.2 M sucrose, but forgot to label them. After realizing the error, the assistant randomly labeled the flasks containing these four unknown solutions as flask A, flask B, flask C, and flask D. Design an experiment, based on the principles of diffusion and osmosis, that the assistant could use to determine which of the flasks contains each of the four unknown solutions. Include in your answer (a) a description of how you would set up and perform the experiment: (b) the results you would expect from your experiments: and (c) an explanation of those results based on the principles involved. (Be sure to clearly state the principles addressed in your discussion.)
