Answer:
The second one is the answer
<u>Answer:</u> The correct answer is Option A.
<u>Explanation:</u>
Mole ratio is defined as the ratio between the stoichiometric coefficients of the molecules present in the chemical reaction.
For the given balanced chemical equation:
![3Fe+4H_2O\rightarrow Fe_3O_4+4H_2](https://tex.z-dn.net/?f=3Fe%2B4H_2O%5Crightarrow%20Fe_3O_4%2B4H_2)
By Stoichiometry of the reaction:
3 moles of iron metal reacts with 4 moles of water to produce 1 mole of iron oxide and 4 moles of hydrogen gas.
The mole ratio of ![Fe_3O_4:Fe=1:3](https://tex.z-dn.net/?f=Fe_3O_4%3AFe%3D1%3A3)
Hence, the correct answer is Option A.
Nuclear fusion in the sun involves hydrogen (H) atoms
combining to form helium (He). A student claims that since the atmosphere
contains hydrogen, any fusion reaction on Earth would result in an uncontrolled
chain reaction. What is wrong in the student’s reasoning is that the uncontrolled
chain reactions can only happen during nuclear fission.
