Answer:
525°C is the maximum safe operating temperature the engineer should recommend for this reaction.
Explanation:
Volume of the cylindrical container = V = 
Height of the vessel = h =60.0 cm
Diameter of the vessel = d = 50.0 cm
Radius of the vessel = r = 0.5d = 25.0 cm


1 mL = 0.001 L
117,809.72 mL = 117,80972 L ≈ 118 L
Pressure of the gas in vessel = P = 7.40 MPa = 

1 atm = 101325 Pa

Mass sulfur hexafluoride gas = 19.2 kg = 19200 g
1 kg = 1000 g
Moles of sulfur hexafluoirde = 
Temperature of the gas in vessel = T
Using an ideal gas equation :


T = 797.8 ≈ K 798 K
T = 798 - 273°C = 525°C
525°C is the maximum safe operating temperature the engineer should recommend for this reaction.
answer this is so hard its impossible butt I'll ask my dad
Ionic compounds are made up of cations and anions.
So, C would be the correct answer
Answer:
Felsic, intermediate, mafic, ultramafic
Explanation:
Ferromagnesian igneous rocks are those that contains ferromagnesian silicate minerals with magnesium and iron in their structure. Some of these minerals are olivine, pyroxene, amphibole, calcic palgioclase e.tc. Ultramafic rocks have these silicate minerals in them. They impart a dark coloration on their outlook.
Felsic minerals on the other extreme are rich in non-ferromagesian minerals such as quartz, feldspars which lacks magnesium and iron in their structures. The intermediate and the mafic igneous rocks are a mix between the two extremes. So in terms of ferromagnesian silicates component:
felsic < intermediate < mafic < ultramafic
