Context and question: Roughly one quarter of all zinc output in the United States (2009), is consumed in the form of zinc compounds; a variety of which are used industrially. Zinc oxide is widely used as a white pigment in paints, and as a catalyst in the manufacture of rubber. It is also used as a heat disperser for the rubber and acts to protect its polymers from ultraviolet radiation (the same UV protection is conferred to plastics containing zinc oxide). The semiconductor properties of zinc oxide make it useful in varistors and photocopying products. The zinc zinc-oxide cycle is a two step thermochemical process based on zinc and zinc oxide for hydrogen production.
What kind of process is the zinc zinc-oxide cycle?
Answer: thermochemical
Context and question: The lower (Triassic) boundary is set by the PermianTriassic extinction event, during which approximately 90% to 96% of marine species and 70% of terrestrial vertebrates became extinct. It is also known as the "Great Dying" because it is considered the largest mass extinction in the Earth's history. The upper (Cretaceous) boundary is set at the CretaceousTertiary (KT) extinction event (now more accurately called the CretaceousPaleogene (or KPg) extinction event), which may have been caused by the impactor that created Chicxulub Crater on the Yucatan Peninsula. Towards the Late Cretaceous large volcanic eruptions are also believed to have contributed to the CretaceousPaleogene extinction event. Approximately 50% of all genera became extinct, including all of the non-avian dinosaurs.
How many terrestrial species were created during the PermianTriassic era?
Answer: unanswerable
Context and question: Scholars now believe that the Arian Party was not monolithic, but held drastically different theological views that spanned the early Christian theological spectrum. They supported the tenets of Origenist thought and theology, but had little else in common. Moreover, many labelled "Arian" did not consider themselves followers of Arius. In addition, non-Homoousian bishops disagreed with being labeled as followers of Arius, since Arius was merely a presbyter, while they were fully ordained bishops. However, others point to the Council of Nicaea as proof in and of itself that Arianism was a real theological ideology.[citation needed]
Did Arians have one set of beliefs?
Answer:
not monolithic
