Eta Carinae could be as large as 180 times the radius of the Sun, and its surface temperature is 36,000-40,000 Kelvin. Just for comparison, 40,000 Kelvin is about 72,000 degrees F. So it's the blue hypergiants, like Eta Carinae, which are probably the hottest stars in the Universe.
C is the answer because that is an actual chemical change where the sulfur and iron are not separate from each other anymore
Answer: 107 grams
Explanation: got it right on the test
Answer:
41.2 lb/gal
Explanation:
Step 1: Given data
Density of iodine: 4.94 g/mL
Step 2: Convert the mass to grams
We will use the conversion factor 1 lb = 454 g.
4.94 g/mL × (1 lb / 454 g) = 0.0109 lb/mL
Step 3: Convert the volume to gal
We will use the conversion factors 1 gal= 3.785 L and 1 L = 1,000 mL.
0.0109 lb/mL × (1,000 mL/1 L) × (3.785 L/1 gal) = 41.2 lb/gal
