223.4 g of iron can be formed from 6 moles of hydrogen gas.
Explanation:
Fe₂O₃(s) + 3 H₂(g) → 2 Fe(s) + 3 H₂O(l)
Since the given equation is the balanced one, we need 3 moles of hydrogen gas to make 2 moles of iron, so the molar ratio is 3:2. So, from 6 moles of hydrogen gas, we can make few moles of iron as,
Molar mass of iron = 55.85 g
So amount of iron produced = 4 moles × 55.85 g/mol = 223.4 g of iron
beta emission
alpha emission
fission
Answer: A: fusion
Ex:
K.E = mgh at bottom
K.E = 0.18*10*45
K.E = 81J
K.E at the bottom will be equal to P.E at hight.
Answer:
Formally stated, Newton's third law is: For every action, there is an equal and opposite reaction. The statement means that in every interaction, there is a pair of forces acting on the two interacting objects. The size of the forces on the first object equals the size of the force on the second object.
