Because there are limits on how much oil and natural gas is available, and it's best not to waste them, but to use them economically
You could use spectroscopy as a definite method, or you could use an oxidizing agent that reacts with O2 (Oxygen), such as Iron, Nitric Acid, or halogen compounds.
I think it is helium, I could be wrong.
A gas stove or electricity
Because neither one is economically viable. First, the cost of converting thousands of processes built over 200 years is greater than any gains made in using the metric system. As to universal health care, we have a free market that sets the rates based on customer/patient need. That free market just took a serious hit today with ObamaCare. We previously believed that each person was responsible for themselves and their family. Now we have been told it will be the government. Both have, of course, proved economically viable and hugely successful in the rest of the world. Americans stand alone in rejecting the metric system and not caring for their neighbours.
After conducting market research, we identified several viable solutions to increase our company's profits.
It was an economically viable option to use slaves.
Whilst a high pressure would favour the products in equilibrium it is not economically viable to produce and maintain such a high pressure. By use of a Vanadium (V) Oxide cataylst this process is able to be carried out at normal pressure and be economically viable.
Not really at this time. Solar energy would be viable once fossil fuel energy source become possibly double (the cost) of what they are today. This sector is taking a gamble on new environmentally friendly philosophy that the world has recently embraced. Thus, would solar energy ever be economically viable? no doubts it will be just not at this time.
There are none. It will never be prevented.You can prohibit it but always there will be someone some where that will use child labour.There are also countries that refuse to prohibit it because it is economically viable.
Hard drives should be destroyed when they are defective or cannot be economically repaired or sanitized for reuse. Functioning operable hard drives no longer deemed economically viable should be overwritten or degaussed prior to destruction.

In business, we could say feasible, possible -- e.g. That's not a viable/feasible/possible solution. A modern but very informal alternative is doable -- meaning something which we can do.
It doesn't, but as it is a water-plant in early life, it can only be grown where flooding the fields is an economically viable proposition - and the cheapest way is to use rain or surface water.
Rockets don't use nuclear fusion so far. The only "practical" use of fusion energy so far is the hydrogen bomb. A controlled reaction has not been possible - at least, not in a way that is economically viable.

Salesman told me I could use unleaded gas verses premium. Is this true?
