What are " of the following"?
Answer:
47.8 moles of H₂O.
Explanation:
We'll begin by writing the balanced equation for the reaction. This is illustrated below:
2H₂ + O₂ —> 2H₂O
From the balanced equation above,
1 mole of O₂ reacted to produce 2 moles of H₂O
Finally, we shall determine the number of mole of water, H₂O, produced by the reaction of 23.9 moles of O₂. This can be obtained as follow:
From the balanced equation above,
1 mole of O₂ reacted to produce 2 moles of H₂O.
Therefore, 23.9 moles of O₂ will react to produce = 23.9 × 2 = 47.8 moles of H₂O.
Thus, 47.8 moles of H₂O were obtained from the reaction.
I think it’s B
Sorry if I’m wrong
Writing the name for Fe2o3 is a bit more challenging since Fe is a transition metal. this means you need to used parenthesis and Roman Numeral to show the charge on the Fe atoms. in these case each Fe atoms has a charge of +3 so we write Fe2o3 as an iron(III) oxide
Answer is: c. impulse acting on the object.
Momentum is the product of the mass and velocity of an object. It is a vector quantity, possessing a magnitude and a direction in three-dimensional space.
The impulse-momentum change equation: F· t = m · Δ v.
The impulse experienced by the object equals the change in momentum of the object.
