Hey there!
Na + H₂O → NaOH + H₂
First, balance O.
One on the left, one on the right. Already balanced.
Next, balance H.
Two on the left, three on the right. Let's add a coefficient of 2 in front of NaOH and a coefficient of 2 in front of H₂O, so we have 4 on each side.
Na + 2H₂O → 2NaOH + H₂
Lastly, balance Na.
One on the left, two on the right. Add a coefficient of 2 in front of Na.
2Na + 2H₂O → 2NaOH + H₂
This is our final balanced equation.
Hope this helps!

Answer:
126g
Explanation:
Data obtained from the question include:
Mole of Fe = 2.5moles
Molar Mass of Fe = 56g/mol
Mass of Fe =?
Number of mole = Mass/Molar Mass
Mass = number of mole x molar Mass
Mass of Fe = 2.25 x 56
Mass of Fe = 126g
Therefore, the mass in 2.25mol of Fe is 126g

Answer:
A molecule consists in a group of atoms that are electrically neutral and remain stable in a specific configuration through strong chemical bonds. In a substance it is the smallest particle and represents all the physical and chemical properties of it.
On the other hand, an ion consists in a particle that is electrically charged, that is, it is not electrically neutral, and is constituted by a group of atoms or molecules with a positive or negative net charge.
Atoms combine with each other in several ways to form different substances such as elements and compounds. To form this compounds it is necessary to have a pattern which are the molecules and ions. In some cases, with some external energy, an atom can lose or gain one or more electrons, thereby ionizing and forming electrically charged ions, instead in the molecules the atoms join together in groups that share electrons to generate greater stability.
