Answer:
MA = Fr / Fe = 450N/150N= 3.0
Explanation:
One mole of any gas at STP is about 22.4 liters (even for mixtures). This number comes from the ideal gas equation by setting n=1 and STP conditions:
V=nR/P =1 mole x 0.08206Latm/molK x 237K/1atm = 22.4L
so jsut divide: 893L/22.4L/mole = 39.9 moles
Answer:
The correct answer is hydrogen.
Explanation:
Stars in the main sequence will remain in the main sequence as long as their cores contain hydrogen atoms. This is because main sequence stars run on the hydrogen atoms within their core to prevent them from falling to the force of gravity. Once these hydrogen atoms run out, the star is no longer considered a main sequence star, gravity takes hold, and the star collapses.
