We will get Plagioclase as phenocryst in a porphyritic basalt using Bowmen's reaction series.
Porphyritic basalt is mafic i.e. it has low silica content and have higher melting pointthanfelsic which have higher silica content .Porphyritic basalt'smineral composition is Calcium Plagioclase . Phenocrystis large crystal , early forming igneous rock.
Thus , on coolingplagioclase will be seen as phenocryst which is clear from Bowmen's reaction series because it is present on right side of series at higher temperature range in continuous branch in mafic region.
The correct answer is A. Analgesic are used to treat all forms of pain and because of their wide availability people buy them without proscription. This leads to a lot of undesirable side effects.
a single-replacement reaction replaces one element for another in a compound. A double-replacement reaction exchanges the cations, or the anions, of two ionic compounds.
