Answer:
=2023.04 grams
Explanation:
Magnetite reacts with hydrogen to produce Iron metal and steam. Steam instead of water is produced as the reaction occurs at temperatures above the boiling point of water.
Fe₃O₄ + 4 H₂ → 3 Fe +4 H₂O
From the equation, 1 mole of Fe₃O₄ reacts with 4 moles of H₂.
69.76 grams of H₂ has the following number of moles.
Number of moles= mass/RAM
=69.76/2
=34.88 moles.
The reaction ratio of Fe₃O₄ to H₂ is 1:4
Thus number of moles of magnetite= (1×34.88)/4
=8.72 moles.
Mass= moles × RAM
=8.72 moles × (56×3+16×4)
=2023.04 grams
With the current energy shortage, nuclear energy can be seen as a more practicle option
Answer:
C. its particles move farther apart and the substance becomes a gas.
Explanation:
A. is wrong because moving closer together creates a solid, not a gas.
B. is wrong because moving father apart creates a gas, not solid.
C. is correct because moving farther apart creates a gas.
D. is wrong because when heat is added particles spread apart because they vibrate faster. Although, in a solid the particles are closer together.
- Just know the states of matter and how the particles move and that will help with this problem.
Answer:
That's because Earth is so much larger. If the moon were bigger enough, it might be able to “pull a Charon” and lock us in as well. “It might be that you'd have to take a vacation to the other side of the Earth to ever see the moon,” Siegler said. More than that, becoming tidally locked with the moon would change time.
Explanation:
Methane is CH4
Ethane is. C2H6
Method by ☆cracking alkanes☆
In this case, by cracking methane
Cracking alkanes is the method used to split a long alkane structure into smaller alkanes using high temperature and a catalyst.
e.g. C2H6 -> CH4 + CH2
