Consider bowen's reaction series. which mineral would you expect to see as a phenocryst in a porphyritic basalt?

Chemistry

Maru [420]2 years ago

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 point than felsic which have higher silica content . Porphyritic basalt's mineral composition is Calcium Plagioclase . Phenocryst is large crystal , early forming igneous rock.

Thus , on cooling plagioclase 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.

According to the following position vs. Time graph the bicyclist was
julia-pushkina [17]

Answer:

According to the following position vs. Time graph the bicyclist was : D

D. Not moving for the first two seconds, then begin moving at the constant speed.​

Explanation:

Speed = \frac{Distance}{time}

Along Y-axis = Distance in meters

Along X-axis = Time taken in second

  • For first 2 seconds the The object has not changed its position.There is Zero distance covered.So , Speed = 0
  • After 2 second,The Object changed the distance by equal amount in equal interval of time.(Uniform Speed).Hence at each point after 2 second, there is same value speed

Suppose a gas starts with a volume of 4.52L, temperature of 23 C, and pressure of 102,00 Pa. If the volume changes to 4.83L and
ivanzaharov [21]

Answer:

The answer to your question is     P2 = 84.16 kPa

Explanation:

Data

Volume 1 = V1 = 4.52 L            Volume 2 = V2 = 4.83 l

Pressure 1 = P1 = 102 kPa        Pressure 2 = P2 = ?

Temperature 1 = T1 = 23°C      Temperature 2 = T2 = -12°C

Process

1.- Convert the temperature to °K

Temperature 1 = 23 + 273 = 296°K

Temperature 2 = -12 + 273 = 261°K

2.- Use the Combined Gas law to solve this problem

                  P1V1/T1 = P2V2/T2

-Solve for P2

                  P2 = P1V1T2 / T1V2

-Substitution

                  P2 = (102)(4.52)(261) / (296)(4.83)

-Simplification

                  P2 = 120331.44 / 1429.68

-Result

                  P2 = 84.16 kPa
