Here is a question about this article: Consequently, steam reforming typically employs an excess of H
2O. Additional hydrogen can be recovered from the steam by use of carbon monoxide through the water gas shift reaction, especially with an iron oxide catalyst. This reaction is also a common industrial source of carbon dioxide:
What is the answer to this question: How can it be recovered through steam?
****
So... use of carbon monoxide through the water gas shift reaction

Here is a question about this article: As one of the most successful shows on U.S. television history, American Idol has a strong impact not just on television, but also in the wider world of entertainment. It helped create a number of highly successful recording artists, such as Kelly Clarkson, Daughtry and Carrie Underwood, as well as others of varying notability.
What is the answer to this question: What show helped launched the career of Daughtry?
****
So... American Idol

Here is a question about this article: There exist two different spin isomers of hydrogen diatomic molecules that differ by the relative spin of their nuclei. In the orthohydrogen form, the spins of the two protons are parallel and form a triplet state with a molecular spin quantum number of 1 (12+12); in the parahydrogen form the spins are antiparallel and form a singlet with a molecular spin quantum number of 0 (1212). At standard temperature and pressure, hydrogen gas contains about 25% of the para form and 75% of the ortho form, also known as the "normal form". The equilibrium ratio of orthohydrogen to parahydrogen depends on temperature, but because the ortho form is an excited state and has a higher energy than the para form, it is unstable and cannot be purified. At very low temperatures, the equilibrium state is composed almost exclusively of the para form. The liquid and gas phase thermal properties of pure parahydrogen differ significantly from those of the normal form because of differences in rotational heat capacities, as discussed more fully in spin isomers of hydrogen. The ortho/para distinction also occurs in other hydrogen-containing molecules or functional groups, such as water and methylene, but is of little significance for their thermal properties.
What is the answer to this question: What state are the protons in when in the orthohydrogen form?
****
So...
triplet state
