Answer:
The answer is "They have longer lifespans" and "They consume their hydrogen fuel slowly"
Explanation:
A star is a galactic item comprising of luminous spheroid of plasma held together by its own gravity. The closest star to Earth is the Sun. Numerous different stars are obvious to the unaided eye from Earth during the night, showing up as a large number of fixed radiant focuses in the sky because of their gigantic separation from Earth.
For the vast majority of its dynamic life, a star sparkles because of atomic combination of hydrogen into helium in its center, delivering energy that navigates the star's inside and afterward transmits into space. Practically all normally happening components heavier than helium are made by heavenly nucleo-synthesis during the star's lifetime, and for certain stars by supernova nucleo-synthesis when it detonates. Close to the furthest limit of its life, a star can likewise contain degenerate issue
A star's life starts with the gravitational breakdown of a vaporous cloud of material made essentially out of hydrogen, alongside helium and follow measures of heavier components. At the point when the heavenly center is adequately thick, hydrogen turns out to be consistently changed over into helium through nuclear fusion, producing energy all the while.
Answer:
294.2g
Explanation:
C3H8 + 5O2 —> 3CO2 + 4H2O
Molar Mass of C3H8 = (3x12) + (8x1) = 36 + 8 = 44g/mol
Molar Mass of O2 = 16x2 = 32g/mol
Mass of O2 from the balanced equation = 5 x 32 = 160g
From the equation,
44g of C3H8 was completely consumed by 160g of O2.
Therefore, 80.9g of C3H8 will be consume by = (80.9x160)/44 = 294.2g of O2
Therefore, 294.2g of O2 is needed
<span>According to Beer’s Law, A=Ebc, under ideal conditions, a substance’s concentration and its absorbance are directly proportional: a high-concentration solution absorbs more light, and solution of lower concentration absorbs less light. Since concentration and absorbance are proportional, Beer’s Law makes it possible to determine an unknown concentration of phosphate after determining the absorbance.</span>
